Good afternoon,

You described the issue very clearly — your Mitsubishi Attrage/Mirage 2013 producing smoke and shutting off in traffic usually points to a combination of compression loss and idle system failure, both of which need proper diagnosis before considering an engine replacement.

⸻

🔧 Technical Breakdown (Ryan Automotive Diagnostic Insight)

1️⃣ Smoking Issue
• Often caused by worn piston rings, valve seals, or a clogged PCV valve.
• 🔹 Blue smoke → oil burning inside the combustion chamber.
• 🔹 White smoke → coolant leakage or head gasket failure.
• 🔹 Black smoke → rich fuel mixture (injector or MAF sensor fault).

2️⃣ Engine Shutting Off in Traffic
• Common causes include a dirty throttle body, failing idle control valve, or weak fuel pump.
• In some cases, a crankshaft position sensor or ECU calibration issue may also trigger intermittent engine cut-off at low speed.

3️⃣ Recommended Fix Steps
✅ Perform a computerized diagnostic scan — read all stored fault codes and live data.
✅ Run a compression test to confirm piston and ring condition.
✅ Clean the throttle body and inspect the idle control motor.
✅ Check fuel pressure, injector balance, and air intake sensors.
✅ Only consider engine replacement if compression is very low and oil consumption is severe.

⸻

Does anyone here know where I can get these honda transmission pressure switches from?
28600-RAY-003 - 4th pressure switch
28610-RAY-003 - 3rd pressure switch

Good morning.

Please my honda accord eod v6 2003 jerks while changing gear. Most especially from gear 1 to 2 and sometimes 3. This usually happen when i accelerate slowly but when i drive fast, i hardly notice. And i sometimes notice the 'green' D symbol on the dash board blinking.
Any solution to this?

Greetings house,
Please help my Toyota venza alarm keeps going off even when all doors are locked.what could be the problem

Thank you for reaching out, and excellent description of your Honda Accord EOD (V6, 2003) issue — that helps narrow down the diagnosis precisely.

⸻

🔧 Technical Breakdown — Gear Jerking & Blinking “D” Indicator

1️⃣ Likely Causes:
From our experience diagnosing the V6 EOD transmission (typically the BAYA or BYBA unit), jerking between 1st–2nd and 2nd–3rd gear combined with a blinking “D” light indicates the transmission control system has detected a fault. The top causes include:
• Worn or slipping pressure control solenoids (A/B/C) inside the transmission valve body.
• Dirty or degraded ATF (Automatic Transmission Fluid) — Honda transmissions are sensitive to fluid condition; wrong or old ATF causes delayed shifts and jerking.
• Faulty transmission speed sensors (input or output sensor) causing the TCM to misread shift timing.
• Torque converter clutch (TCC) malfunction — often responsible for jerking during low-speed acceleration.
• Internal clutch wear or hydraulic pressure drop, especially if maintenance intervals were skipped.

⸻

2️⃣ Symptoms Breakdown (What You’re Experiencing):
• Jerks during light acceleration: usually means hydraulic pressure fluctuation due to clogged valve or weak solenoid.
• Smooth at higher speeds: fluid pressure stabilizes at higher RPM, masking the fault.
• Blinking green “D” light: this is not a random light — it’s the TCM warning indicator, same as a check-engine light but specifically for the transmission.

⸻

3️⃣ Recommended Fix Steps:
To avoid unnecessary part replacement, here’s the proper diagnostic flow:
✅ Step 1: Perform OBD-II scan focusing on transmission-related codes (P07xx range). The blinking D guarantees there’s a stored code.
✅ Step 2: Inspect ATF condition — color should be bright red and clean. If it’s brown or burnt, a fluid change (not flush) using Honda ATF-Z1 or DW1 is mandatory.
✅ Step 3: Check pressure control solenoids and shift solenoids — resistance and response test required. Replace any faulty ones as a set if possible.
✅ Step 4: Inspect speed sensors (input/output) — they’re inexpensive and common failure points on the EOD.
✅ Step 5: After fixing, clear the fault codes, perform adaptive shift relearn, and test-drive with a diagnostic tool monitoring live data.

⸻

🧠 Professional Summary

Your EOD’s transmission is not “gone,” but the jerking and blinking D light are early warning signs. Ignoring them can lead to full clutch burn or total transmission failure. The right move is a proper scan, ATF inspection, and solenoid/sensor evaluation — not random fluid flushes or electrical guesswork.

Greetings house,
Please help my Toyota venza alarm keeps going off even when all doors are locked.what could be the problem

Good day. Thank you for your question regarding your Toyota Venza alarm system. You’re right — we’ll need a bit more detail such as the model year and engine type, because electrical configurations differ slightly between early models (2009–2012) and later ones (2013–2015). However, let’s go through the most likely causes and solutions based on the Venza system design.

⸻

🔧 Technical Breakdown — Alarm Triggering Randomly

1️⃣ Likely Causes:
The Venza’s factory alarm is linked to the Body Control Module (BCM) and relies on door, hood, and trunk sensors to confirm everything is properly closed. When the alarm goes off by itself, it’s usually due to:
• Faulty or weak door-ajar sensor (commonly the driver or tailgate switch).
• Weak 12V battery or unstable voltage — low battery voltage can confuse the alarm circuit and trigger false signals.
• Hood latch switch malfunction — this tiny sensor is often overlooked; corrosion or loose contact can trigger the alarm even when the hood is closed.
• Aftermarket alarm or remote starter interference — if the car was fitted with a secondary alarm or remote system, both signals may conflict.
• Moisture or water entry into a door switch connector or the BCM (especially during rainy season).

⸻

2️⃣ Symptoms Breakdown:
• Alarm sounds randomly when parked: classic sign of intermittent sensor contact or battery voltage drop.
• Alarm triggers right after locking: often points to a faulty door latch switch not reporting “closed” to the BCM.
• Occurs mostly at night: this may be due to temperature or humidity changes affecting a weak switch or low battery.

⸻

3️⃣ Recommended Fix Steps:
✅ Step 1: Start with battery voltage test — ensure it reads between 12.4V–12.7V with ignition off. Replace if weak.
✅ Step 2: Inspect door and hood switches — manually press each latch switch and listen for the click or watch the dashboard “door open” indicator. The faulty one will usually flicker.
✅ Step 3: If the vehicle has an aftermarket alarm, temporarily disable or disconnect it to confirm if it’s the source.
✅ Step 4: Use a scan tool (BCM scan) to check for “alarm trigger history.” It will log which sensor caused the last trigger — saves you time guessing.
✅ Step 5: Clean connectors and apply dielectric grease to the hood latch sensor if corrosion is found.

⸻

🧠 Professional Summary

False alarm triggers in the Toyota Venza are almost always sensor or voltage related, not a system failure. The right approach is to perform a battery health check, door/hood switch test, and BCM scan before replacing any parts.

If possible, please share your Venza’s model year and engine type (e.g. 2.7L or 3.5L) — we’ll guide you with exact wiring layout and alarm circuit locations for your version.

hontimmy:
Hello House,
I recently notice my Lexus RX350 013 check engine light always blinking when driving like 15 minutes up, esp when on top speed on the road.

Currently, the car works perfectly for some moment and later experiencing acceleration hesitation.

Did a scan today, I replace two coil and 3 spark plug, it was good for some moments, after driving around for awhile, engine check started blinking again.

Nuzzle was check, injector was cleaned and coil and spark plug was also switch, still no solution yet.

I can't rev and and speed higher with my car currently.

AC works fine, everything else also working, I can't accelerate and go on long journey with the blinking check engine to avoid serious issues.

Someone suggested the head gasket should be replaced from the original.

please, Kindly share any option for me

Good day. Thank you for your detailed explanation — that’s exactly the kind of report that helps isolate issues properly. The blinking check engine light on your Lexus RX350 (2013) means the ECU has detected a severe cylinder misfire under load, not a random fault.

⸻

🔧 Technical Breakdown — RX350 Misfire & Blinking Check Light

1️⃣ What’s Happening:
A steady check light means minor faults, but when it starts blinking during acceleration or top speed, it means unburnt fuel is entering the exhaust, risking damage to the catalytic converter.
Since you’ve replaced some coils and plugs already, it’s likely the root cause is either fuel delivery or air metering related, not just ignition.

⸻

2️⃣ Common Root Causes (2GR-FE Engine):
• Weak or dirty fuel injectors — they flow unevenly at high RPM, causing lean misfire.
• Mass Air Flow (MAF) sensor contamination — gives wrong readings at high airflow, confusing the ECU.
• Vacuum leaks or bad intake gasket — more noticeable after engine warms up.
• Weak fuel pump or low fuel pressure — causes hesitation on acceleration.
• Low compression or valve leak — less common, but should be tested before assuming head gasket issues.

⸻

3️⃣ Proper Diagnostic Flow (Recommended at Ryan Automotive Workshop):
✅ Step 1: Conduct a full live-data scan using a professional OBD-II tool (not just basic code reader).
✅ Step 2: Monitor misfire counts, fuel trims, and MAF voltage to pinpoint the affected cylinder.
✅ Step 3: Perform a fuel pressure test under load to confirm delivery.
✅ Step 4: Clean the MAF sensor and throttle body with approved cleaner.
✅ Step 5: If misfire persists, do a compression test before touching the head gasket.

⸻

⚠️ Important Clarification

Please do not replace the head gasket unless a compression or coolant test confirms leakage. On the RX350, gasket failure is rare unless the engine overheated. Most blinking check-light cases come from fuel/air imbalance or weak injectors, not a blown gasket.

⸻

🧠 Professional Summary

Your RX350’s issue is still within repairable range — no need for random part changes.
Bring the vehicle in for a precision live-data diagnosis to confirm the exact fault and avoid further converter or engine damage.

For a proper and transparent inspection, we recommend taking the vehicle to:

haykay2005:
Pls,

I recently bought a 2006 Honda Civic, and one of the first things I noticed is that the fan is connected directly. My scan result also shows two codes — P2413 and P2185. I usually scan my car and tell my mechanic what to fix based on the codes generated, and that approach has been working for me.

Now, he agrees with me on the first code, which relates to the EGR, but he doesn’t want to return the fan to its factory setting. I’d rather have that done elsewhere.

I need a good mechanic around the Ogba/Abule Egba axis who can sort this out for me. I don’t want to argue with this Azeem. I understand gassuz doesn’t like working on this car.

The fuel consumption is high. I used 17 litres of fuel from challenge ibadan to abule Egba, and my calculation is around 17mpg

Please how much do you get the Civic 2006 is it Nigeria used or tokubo ? Planing to get the used

Jonbecks:
It is a Toyota venza 2012 model and the engine is v6 2gr-fe

Good day. Thank you for providing your Toyota Venza details — 2012 model with the 3.5L V6 2GR-FE engine. Now we can tailor the alarm diagnostic specifically for your vehicle.

⸻

🔧 Technical Breakdown — Alarm Triggering Randomly (2012 Venza, V6 2GR-FE)

1️⃣ Likely Causes:
For your 2012 Venza, the alarm system is integrated with the Body Control Module (BCM) and uses the following sensors: driver and passenger door, tailgate, and hood. Random triggers are most commonly caused by:
• Driver or tailgate door-ajar switch fault — the 2012 Venza is known for intermittent driver-side switch failure.
• Weak or fluctuating 12V battery voltage — your 2GR-FE engine and BCM are sensitive to voltage dips; even minor drops can trigger alarms.
• Hood latch switch corrosion or loose connector — a frequent issue in humid environments.
• Aftermarket accessories interference — if a remote starter or secondary alarm is installed, signals may conflict with the factory system.
• Moisture ingress — water can enter connectors at the doors, tailgate, or under the dash near the BCM.

⸻

2️⃣ Symptoms Breakdown:
• Alarm sounds randomly during parking — points to intermittent sensor or voltage issues.
• Alarm triggers immediately after locking — likely a door switch not reporting closed to the BCM.
• Occurs during night or high humidity — environmental conditions exacerbate weak sensors.

⸻

3️⃣ Recommended Fix Steps:
✅ Step 1: Test battery voltage — should read 12.4V–12.7V with ignition off. Replace if below 12.4V.
✅ Step 2: Inspect all door, tailgate, and hood switches — manually actuate each while watching the “door open” indicator; a flickering indicator usually identifies the faulty switch.
✅ Step 3: If aftermarket alarms are installed, temporarily disable them to rule out interference.
✅ Step 4: Use a BCM scan tool to check the “alarm trigger history” — your 2012 Venza logs the exact sensor causing each trigger.
✅ Step 5: Clean all suspect connectors and apply dielectric grease to prevent corrosion, especially on the hood latch sensor.

⸻

⚙️ Ryan Automotive Workshop Professional Take

We’ve handled multiple 2012 Venza V6 2GR-FE alarm issues. In most cases, the driver door-ajar switch or tailgate switch was the culprit. Using a BCM scan tool often pinpoints the exact sensor within minutes, avoiding unnecessary part replacements. We’ve also resolved false triggers caused by battery weakness or aftermarket alarm conflicts — applying dielectric grease and securing connectors gives a permanent fix in most cases.

⸻

🧠 Professional Summary

For your 2012 Venza, false alarm triggers are almost always sensor or voltage-related, not a full system failure. Begin with a battery health check, inspect door, tailgate, and hood switches, and perform a BCM alarm trigger history scan. This structured approach ensures accurate diagnosis and avoids costly trial-and-error replacements.

Hi sir

The 2016 GLE43 Coupe I’m working on shows this DTC code. When you drive the car at high speed, an error message appears (see image 1). After diagnosing it, this DTC code comes up (see image 2). What could be the cause?

Hello sir,

Thank you for providing the details and images regarding your 2016 Mercedes GLE43 Coupe. We’ve carefully reviewed the DTC code and the cluster warning.

⸻

🔧 Technical Breakdown (Diagnostic Insight)

1. Cause Analysis
• The DTC P02184B indicates that Transmission Oil Temperature Sensor 1 has detected a temperature exceeding safe limits.
• This typically happens when the transmission fluid overheats, which can be caused by:
• Low or degraded transmission fluid.
• Faulty transmission oil temperature sensor.
• Blocked or restricted transmission cooler or cooler lines.
• Heavy load driving, aggressive acceleration, or extended high-speed runs.
• Potential software or ECU calibration issues (less common).

2. Symptoms Observed
• Cluster warning: “Stop vehicle, leave engine running, wait transmission cooling.”
• Possibly intermittent gear shift hesitation, delayed engagement, or reduced performance if the system limits torque to protect the transmission.
• The fault is current and stored, meaning the issue is actively detected and has occurred in previous cycles.

3. Recommended Fix Steps
• Step 1: Check transmission fluid level and condition. Replace or top up with manufacturer-approved fluid if low or burnt.
• Step 2: Inspect and test the transmission oil temperature sensor; replace if defective.
• Step 3: Inspect the transmission cooler and lines for blockage, leakage, or damage. Clean or repair as necessary.
• Step 4: Clear the DTC after repairs and perform a test drive under monitored conditions to ensure proper sensor readings and transmission cooling.
• Step 5: If the issue persists, a diagnostic scan and ECU software update may be required.

⸻

⚙️ Ryan Automotive Workshop Professional Take

We’ve encountered this exact scenario on multiple GLE43, E63 AMG, and other high-performance AMG models. In most cases, the root cause was low/degraded transmission fluid combined with a slightly faulty sensor. After replacing the sensor and topping up with fresh fluid, the overheat warnings cleared immediately. We’ve also seen cases where a clogged cooler line caused intermittent overheating at high speed, which required cleaning to fully resolve the DTC.

⸻

✅ Professional Summary
• Primary diagnosis: Transmission fluid overheat detected by sensor 1.
• Most likely causes: Low or old transmission fluid, sensor fault, or cooler blockage.
• Action plan: Inspect fluid, replace sensor if needed, check cooler integrity, clear code, and test drive.

Stop driving it, scan that car transmission if any code comes up, you know what to do, if none comes, you'd need to delve deeper to finding the reasons why it does that. If you keep driving that car with that fault, you'd destroy the transmission. It's not a cheap transmission. If you're in Abuja, feel free to contact me for diagnostics and repairs.

Good morning sir,

Your question is well noted — however, please always try to specify your exact vehicle details next time (for example: 2005 Lexus LX470 or 2006 Toyota Land Cruiser V8) because even though both models share the same Toyota platform (the LX470 is technically the luxury version of the Land Cruiser 100 Series), their transmission and cooling systems can differ slightly in calibration and parts configuration.

Now let’s go over your complaint in a proper diagnostic format 👇

⸻

🔧 Complaint Summary

“A/T OIL TEMP” light appears after driving for a few minutes, followed by sluggish acceleration.

⸻

🧠 Technical Breakdown

1️⃣ Meaning of the Warning

The A/T OIL TEMP light means Automatic Transmission Fluid (ATF) is overheating.
When that happens, the transmission control module enters limp or protection mode — that’s why the vehicle refuses to accelerate normally.

⸻

2️⃣ Common Causes
• Low or degraded ATF – Old or burnt transmission fluid loses its cooling capacity, causing high temperature buildup.
• Blocked or weak transmission cooler – The small radiator (transmission cooler) in front of your main radiator may be partially blocked by debris or internal sludge.
• Faulty radiator with integrated cooler – Some Land Cruiser/LX models use a shared radiator; if it’s weak or clogged, ATF will overheat.
• Bad thermostat or fan clutch – Engine temperature can indirectly cause transmission overheating if cooling airflow is weak.
• Failing torque converter or solenoids – When these start slipping, fluid shears and overheats quickly, especially in stop-and-go driving.

⸻

3️⃣ Recommended Diagnostic Steps
1. Scan the vehicle – Use a professional diagnostic tool (Techstream or Autel) to check for transmission temperature codes or pressure faults.
2. Inspect ATF condition – Pull the dipstick when warm; fluid should be bright red, not dark brown or smelling burnt.
3. Clean and flush the transmission cooler line and confirm coolant isn’t mixing with ATF inside the radiator.
4. Check cooling fan operation – Ensure the viscous fan clutch engages fully when hot.
5. Replace fluid and filter – Use only Toyota ATF Type T-IV or WS (depending on model year).

⸻

⚙️ Ryan Automotive Workshop Professional Take

We’ve handled this same complaint multiple times on both LX470 and Land Cruiser 100-series V8 models.
In many cases, the transmission cooler was either clogged internally or the radiator’s built-in cooler had failed, causing the ATF to overheat.
After flushing the system, replacing the radiator, and refilling with OEM ATF, the issue completely disappeared — no more warning light, and normal acceleration returned.

⸻

✅ Professional Summary

Your transmission is going into self-protection mode because the ATF is too hot.
Don’t keep driving it like that — every time it overheats, the clutches wear faster.
Have a proper diagnostic check done immediately, starting with ATF temperature data, cooler flow, and radiator condition.

And next time, please include full vehicle details (brand, model, year, engine type) — it helps professionals like us give you the exact solution for your specific setup.

• Step 1: Check transmission fluid level and condition. Replace or top up with manufacturer-approved fluid if low or burnt.
• Step 2: Inspect and test the transmission oil temperature sensor; replace if defective.
• Step 3: Inspect the transmission cooler and lines for blockage, leakage, or damage. Clean or repair as necessary.
• Step 4: Clear the DTC after repairs and perform a test drive under monitored conditions to ensure proper sensor readings and transmission cooling.
• Step 5: If the issue persists, a diagnostic scan and ECU software update may be required.

⚙️ Ryan Automotive Workshop Professional Take

We’ve encountered this exact scenario on multiple GLE43, E63 AMG, and other high-performance AMG models. In most cases, the root cause was low/degraded transmission fluid combined with a slightly faulty sensor. After replacing the sensor and topping up with fresh fluid, the overheat warnings cleared immediately. We’ve also seen cases where a clogged cooler line caused intermittent overheating at high speed, which required cleaning to fully resolve the DTC.

✅ Professional Summary
• Primary diagnosis: Transmission fluid overheat detected by sensor 1.
• Most likely causes: Low or old transmission fluid, sensor fault, or cooler blockage.
• Action plan: Inspect fluid, replace sensor if needed, check cooler integrity, clear code, and test drive.

Thanks for your insight.

The car is okay now, the transmission oil cooler was the problem.
