Pls drop d name as long as it is d cable type, lemme do a review on it. Thanks

Seems price has increased

Promzy99:
I wud luv 2 get a gud scanner too but nt more than 10k budget. Even if it is only engine faults it can diagonise. But it shud be one with a plugin cable nt bluetooth. Thanks.

You can also get a scanner than can diagnose basic car codes on Jumia. The cost is less than 10k. It's not the finest but it can do what I want it to do and even more. Got mine from there.

Kookny:
similar issue here, but a higher version of Camry. I don't usually use coolant. I just need to keep refilling water max 3days. No over-heating yet.

Also check your radiator cover to ensure the leakage is not from there.

Etizz:
Have u call him?? How did it go?? Pls I need to know..

Xanie is the person than needs to call gazzuzz by video call and not me. I only commented on Gazzuzz's response.

GAZZUZZ:
Call me on video call with engine bay open, you will fix it your self

Wowwww
Guru!!!

I noticed rough idling on my Corolla 2003. Got it scanned and it threw up the P0300; Multiple Engine misfire.
I changed all four plugs, had the injectors cleaned out...
The vehicle was rescanned and the codes cleared. The check engine goes off
After driving for about 10 minutes the check engine lights again and the rough idling resurfaces.

Now the mechanic is suggesting so many things; timing chain, leaks and even dropping the engine. I'm not comfortable with his guess work...
I bought it toks August last year...

Did you rescan? What codes did it throw after the rough idling resurfaced?

Conner44:
Yes. Check if it’s wiring is loose. If it’s firm then either the sensor itself is bad or your codes are O2 sensor related.

Ok sir. Many thanks for your help.

@conner44
So to conclude...the encircled in red is AF sensor right?

Conner44:
First Pic is the location of your IAT sensor.

Second is the scan codes description

Third and fourth are your components locations.

There is no issue with my IAT sensor which you encircled in red. Could you please send me a pictorial location as you did above of my upstream O2 sensor?

Conner44:
If you look behind your engine, at the part facing the firewall you’d see a metal covering over your exhaust manifold. Your AF sensor is under that pan. If you have a space on your O2 sensor socket and a sensor plugged in but with nowhere to link it to under your front passenger seat then I believe that part of your harness is either hidden (wires bent back/way from where it’s supposed to pop out from) or lost (cut off by a prior auto electrician).

So try to go under your passenger seat with a flashlight and a flat screwdriver, push your passenger seat all the way forward, loosen the single plastic floor carpet fastener, pull back the carpet and look around very carefully. The main harness port where you are supposed to plug in your O2 sensor runs from under that chair towards the handbrake/gear lever part of your car and then straight ahead to the brain box.

You can try doing the checking at night when your eyes can focus well with your flashlight. You would see the plug for your present O2 sensor dangling somewhere under there then look around for the main harness port. Go on YouTube and watch how to plug in the sensor for your car and you’d see everything you need to know.

Thank you very much for this.

Conner44:
Okay that’s settled. If you haven’t changed the brain box of the car before then you should be having emissions malfunction codes if you’re driving with only one sensor. There should be the AF sensor on your exhaust manifold and the O2 sensor at the catalyst part of your exhaust pipe. Have you scanned the car already? Which of the sensors is missing?

The 02 sensor on the catalyst part is present but the rewire said the socket under the drivers seat is missing. Will scan the car for missing sensors (Like AF sensor) when I come back from church. Yesterday's scan threw codes P0135 and P141.

Conner44:
Can I ask how you know for sure that it’s a sulev engine? The sulevs are supposed to have an extra o2 sensor and a different type of catalyst.

Sulev was written on the side glass.

Conner44:
Is your model the one with a SULEV engine? Those are the ones with two sensors.

I just checked, it's a SULEV engine.

Conner44:
Is your model the one with a SULEV engine? Those are the ones with two sensors.

I don't know if mine is SULEV engine. So you mean that some engines come with only one sensor?

@luvinhubby, My rewire says my car doesn't use upstream O2 sensor. It only has one as fitted from the factory. He is the second rewire to say this. Could this be true?

nacozee:
Gurus in the house. My 2010 Toyota Venza V6 averages 12mpg on intercity driving. Is this low for the mileage. I feel it is, and please what could be causing this low mileage.

What can I do to increase it. Really appreciate answers

Below are the specs for your car

Your city driving should be 18mpg.
Your Highway driving should be 25mpg
Combined driving should be 21mpg.

I advise you scan your car and post the error codes here. A number of factors could cause high mileage but let's not do guesswork.

Afuye1:
Pls can I replace my gear oil with oando gear oil? I can't get the recommended DW1 for Honda Accord.

What's your location?

Rumundele:
the of the still same, the gear oil i use is the same as the one posted above

Can't see any brand posted above. In any case try and scan the car and post the results here.

Fedrams:
Good evening. I just bought a Nigerian use Corolla 2005. I observed I used 30liters for 314 I'm in the city. Is tge fuel consumption ok

Thanks roughly about 28mpg.
Not bad at all.

Rumundele:
Gurus in the house i need your help,
My Honda accord DC 07, kick anytime i engaged gear to Drive, and changing from gear 1 to the next one there is a drag back before changing. Not too comfortable with the condition.
I changed the gear oil last in February 2020. What should i do?

Do you remember the name/brand of the gear oil you used?
What is the color of the oil on the dipstick right now?

emma1st:
My mechanic don't have o, unless I come to Lagos

No need to come to Lagos. Buy the device on Jumia. It should be able to pull out basic error codes. And it's also easy to use. Costs starts from 4k. It's called OBD 2 Bluetooth car scanner.

Eddygourdo:
Hello all. Should I remove the thermostat and single cell radiator from my 2007 Honda pilot. Take note it isn't overheating

Don't do any yet. Hope it's coolant in your radiator and not water. Keep driving it but always monitor the temperature gauge well for any unusual changes.

temi4fash:
Please do you know any Honda mechanic that can look at my gear sensors for me.

Sorry bro. Don't know any

temi4fash:
Please do you know any Honda mechanic that can look at my gear sensors for me.

Sorry bro, I don't know anyone that I can recommend to look at your gear sensors.
Perhaps other guys on this forum might help.

Mdtoba:
yes when I scanned it there were code P0131 and p0141

Then rescan the car to confirm those 2 codes have disappeared.

Ikevincent:
Please fellas I just bought Honda accord 2007,recommend a good oil to use

ATF - Honda DW-1
Engine oil - 5W20 or 5W30 depending on mileage

temi4fash:
Please any ideas where is the sensor located??

Check Google for more details.

temi4fash:
Please I need help... The D light of my Honda city is blinking and I got it scanned and it showed P1887.

The oil is gauged and I use CVT oil for it. Please what can I do??

If your vehicle has a P1887 DTC, it means that the switch that lets the ECU know the TCC clutch/torque converter clutch is no longer engaged, is not responding properly. If this happens, the engine and transmission will not function properly together. Which means performance could suffer and safety could be affected.
I suggest you Change your speed sensor.

petrusevents:
Please how can I solve this issue.

If is not a damaged fuse or open circuit then the best solution is to replace both sensors.

Mdtoba:
Car gurus in the house I just bought Nigeria used Honda 2007 Dc the car consume 12liters of petrol for 50km. I just changed the evap amzd Obd 1and 2 sensors but the oil consummation have not improved .I notice that the fan runs directly .what can I do to improve the car oil consumption

Before changing both sensors, were the error codes P0135 and P0141

petrusevents:
Pls can someone give vivid explanation of these codes.

The car consumes so much fuel lately

Both your upstream and downstream oxygen sensors are malfunctioning. Hence the reason for your cars high fuel consumption. O2 sensors are responsible for the air:fuel ratio of your car to measure the mixture of fuel to air burned.

Hello house, I need urgent help. Can I use Mobil XHP 2000 5w30 or Mobil XHP 3000 5w40?

I was told that full synthetic oil may not be good for high mileage cars. How true is this?

You didn't specify the car you drive. You also didn't specify the oil you used before or the oil the previous owner used. With these info we can advice you accordingly.
