Thank you very much for your help. I have to just let it slide. I have paid for comprehensive VIN report already; checked in many sites.

kingreign:
Most times, it doesn't work properly. 90% of the time. You're better off buying a tokumbo part.

OmobaDe10th:
Thank you very much
Please do you have any recommendations for a good coolant to use on the same car.
I have realised that most abro coolant in the market are fake

Good day. I have a nissan Altima 2008 2.5l. starting the car it will accelerate well but wen getting to a stop 🛑 light and try accelerating back, it is super slow. Some time when you off it and on it. It will work fine. What is the problem. I will love recommendations. Thank you and happy Sunday

My Honda accord 2000 V6 transmission blinks D4 when driving. It is lazy on first gear (1) and moves well on subsequent one

Scanning with a scan tool threw up 2 codes under the A/T section.
-45-01 Shift Malfunction.
- 41-01 Incorrect Gear Ratio.

How do I fix this? I won't mind any mechanic recommendations here on Lagos mainland that can work on it.

I have an issue for high fuel consumption on my 06 Acura tsx (Honda accord euro).
This issue has been there since i got this car about 6 months ago, previous owner says the can doesn't consume fuel but i know for sure that's cap.
I get 10-12 mpg at average which is very very poor, that's like half of normal milage i should be getting.
I've taken it to different technicians, catalytic converter, new o2 sensors, spark plugs, coolant temperature sensor and other has been replaced. Nothing changed.
Until few months ago i got a small OBD scanner, and with the help of my research online, i was able to diagnose the issue of the car which is that the car has very high short time fuel trim of about 30 most times.

See pic below

JoeSef0:
The issue now is
Most so called rewire (electrician) doesn't even know how a car fuel trim works not to even mention short time fuel trim
And that's making it had for me to find someone that really know and understand how to read a car live data with an OBD scanner.
That's the only way we can know the exact sensor causing the high fuel trim issue.

If yes, where?

Diagnosing with the STFT is not straightforward as compared to the LTFT. Drive the car longer to see what the Long term trim is reading then post reading.

Currently staying in ibadan, i use to stay in Ikorodu lagos

If u were in lagos, would have referred you to @jceesquare.

I drive an 08 tsx. I am not sure it is cool with city driving. Use to complain about the fuel consumption. Bought 0xygen sensor twice. But last xmas, I decided to take it on a trip from lagos to owerri and I drove. At asaba was when I crossed half tank. The road was free. If I powered on, one tank will land me in owerri from lagos. Mine also has a trip meter which shows my fuel consumption reading. I was doing close to 12km per liter which was impressive. Another way to enjoy the car is always have substantial amount of fuel in the car. No dey buy all the 5k,7k fuel. Fill up your tank and watch it.

JoeSef0:
LTFT is usually between -5 to +5
As for the last screenshot, IDK if that has anything to do with fuel consumption, but that's the knly code I've not been able to clear off the car.
I've tried upto 3 tokunbo radiator coolant sensor, didn't work. I even order brand new one online, still didn't work. I've use multimeter to test the connection, i got about 4-5 volts so i assume it's getting power from the ECU

The code has been there since i got the car till now

jceesquare:
If you're getting a ±5 LTFT, then your fuel trim reading is fine.
There are several factors that would make your car run rich or consume more petrol as it were.
1. Dirty MAF sensor and dirty or clogged air filter. You can confirm this by physically inspecting the condition of the air filter. Also confirm if your MAF reading is not beyond 3.0 gram per sec at idle without any load on the car (gear on P, steering straight, foot off the brake and aircon off)
2. Your AF sensor (oxygen sensor) is fine and not clogged with carbon.

Other things to consider are
1. Ensure you're not running bigger than recommended wheel size.
2. Tyres are properly inflated.
3. You're not hauling unnecessary load in the car.
4. You drive responsibly. No hard acceleration and braking.
5. Plan your route well so you don't stay longer than necessary in traffic.

As a bonus, you shouldn't expect factory MPG for the following reasons.
1. Wear and tear on the engine (old age catching up on it)
2. Poor fuel quality with lowere octane rating.
3. Parasitic draw from bad or dying parts on the serpentine belt line. Seizing compressor, power steering, and alternator pulleys.

My colleagues can add to the list if I forgot any.

JoeSef0:
The LTFT readings are normal but the STFT reading aren't normal. A normal reading fuel trim reading should be between -10 to +10. Nothing above nothing below.

I don't think the first gen of Acura Tsx use a MAF sensor, I've confirmed online and checked around the intake hose where MAF sensor are usually connected, nothing. Instead i have one sensor that I don't know the name

As for 02 sensor, i first got a toks downstream sensor, when i didn't see any results, i order both up stream and downstream o2 sensor from china and fixed myself .. it's been like 3 months now


I know I'm not supposed to expect the exact factor rated mpg on the car cos lf it's age. But in my case it's just absurd. I'm getting less than or almost half of the rated fuel efficiency.
I've spoken to other people using my same model car and driven some, they have far better fuel efficiency than mine.
This car share same 2.4l engine as the EOD and crv. Those cars have good fuel efficiency

Good evening experts!


My Toyota Camry 2001 (Envelope) has been of late having issues.

I've personally scanned it with my scanner and my Mechanic has done all he thinks and there's no solution in sight yet.

When I start the car it works fine for a moment and afterwards the whole system changes and the car (RPM) drops to almost zero and shaky.

I've changed the Air Mass Sensor,Fuel pump, injector Nozzles, Serviced the injector system.

Now the engine temperature rises in a very short while and produces black smoke from the exhaust.

Please Help a Brother.
P.S. I just serviced the car too

kingreign:
What's the code from the scan?

kingreign:
Get factory OEM sensors or tokumbo. Chinese sensors or generic sensors most times do NOT work 98% of thr time.

jceesquare:
Yes your STFT shouldn't exceed ±10 if you meet several parameters at idle.
A slightly higher RPM would cause a wrong reading.
Intake leaks would cause a spike and wrong reading.
Any form of load (no matter how little) would give you wrong reading if you want to use that for diagnosis.
Clogged and restricted airflow would not give you good reading.
The list goes on and on.
So you need so much to be in shape to use the STFT to monitor your mpg rate as it shows the computers real time adjustment to a perfect air to fuel ratio, that's why most technicians prefer using the LTFT most especially for remote diagnosis like this.
What year is the Acura again? Strange to hear it does not have a MAF sensor.

longyemi:
I've attached the screenshot from the scanner

I also attached the Live readings from the Sensors too as scanned by the scanner.

Thanks in anticipation

JoeSef0:
First gen Acura tsx 06

If i could just get a well skilled technician, I'm sure it shouldn't be that much of a hassle to fix it.

My RPM is always below 1000 after the car worms up, i think that's normal for all cars at idle

I was recommended to a technician in my area, i was explaining things about the fuel trim to him, this guys was just quiet, i doubt he has heard of fuel trim before, all they know how to do is to replace different parts and sensor without proper diagnostic there by costing car owners unnecessarily spending

Your 1st gen 06 Acura TSX should have a MAF sensor.
I might be wrong though.
