Good morning Gazzuzz,
I have the CEL and VSC off lights on in a 2008 toyota highlander, I scanned it and got a P0051 [Oxygen (A/F) Sensor Heater Control Circuit low ( Bank 2 Sensor 1)] and P0793 Intermediate Shaft Speed Sensor 'A' Circuit No Signal.
The VSC off comes with the P0051 but when I read the sensor in question for continuity on the black cables there was continuity (which online information says indicates the sensor is okay), when I check the source for supply, power is supplied to the sensor. That is confusing for me, I will appreciate your inputs on this. Thanks.

GAZZUZZ:


P0051. If you are sure the sensor is fine, replace the engine ECU.

What did you do about this code? P0793

damyde:


I plan to replace the speed sensor but I wanted to sort out the P0051 and VSC off first as I felt it's more critical (I might be wrong).

Thanks for your input

Having read the importance on this platform... I did mine recently. Thermostat is between N1k-2k and the workmanship is N2k. With less than 5k you should be ok

Oga Gazzuz, Rav4 2004 threw up code P0102, P300 to P304.
MAF and injector cleaned with Cab cleaner yet car can't fire normally. Finds it difficult to accelerate and picks fire randomly.

Spark plug changed and Ignition coil changed for all plugs yet no remedy.
If fuel is fed directly it fires normally but can't take up adequate fuel from the injector lines.
What do you think should be done, Sir?

GAZZUZZ:


Look for a large air leak between throttle body to airflow meter.

GAZZUZZ:


First driving really fast should not cause the codes that popped..

Interestingly you have a catalyst converter code affecting only one bank (bank 2 front of the engine) in a V6 engine. Catalytic converter codes are very common in older cars and cars imported into Nigeria as they get stolen all the time before or after shipping by port rats. In your case it might have aged and burnt out.

You have 3 options, replace catalytic converter with a used one , replace with a refurbished one or install an oxygen sensor spacer. Either option will work if done well. Also you should inspect the bank1 .

The incorrect purge flow from evaporative emission system might be a leak on the engine side. This could cause startup issues especially if the purge valve is stuck open.

proclinician:


Pls is this a leak of fuel, engine oil or anointing oyel? Kindly specify.

In 5w20 and 5w30 which is best to use for Honda pilot 2003 in Nigeria ? V6 Engine

GAZZUZZ:


Depends on a lot of factors, mainly what type of engine oil/oil grade had been previously used on the engine and for how long , and the oil drain interval

madgoat:


I thought u always recommend 5W30 or has something changed again?

vkyburnz:
My Toyota Corolla 1.8GL 2006 model thirst/guzzles fuel like a power hungry lad (in the region of 18litres/40km). What could be the cause of this? I'm really concerned. Any info to help fix this will be greatly appreciated. Thanks

GAZZUZZ:


As it is he has options based on the answers to the questions I raised

Johnsonkeyz2019:


The current oil I'm using in it is total quartz 5000 and I think that's wrong coz I do use 5w20 on my former Honda Accord 2006 i4 before I switched to pilot coz of Bad roads that made me need Heights

So I want to know which is better to switch to 5w20 or 5w30? FOR MY HONDA PILOT 03 ...In this scenario and maybe what to expect from whichever I choose

Your car na fuel guzzler oo, is your thermostat still in place? There are many factors that can cause high fuel consumption. My advice scan your car.

Hallos Gazzuzz,

Plead help me o!
I bought a toks Camry 09 Sep-19... good car and drives great. Doing the servicing about 2 weeks later then, my Kazeem observed the oil is quite watery (now, I think the US owner uses 0W20/5W20 as recommended on the car) and advised I use Mobil XHP which had been in use till now.

1. Can I revert to the recommended oil?
2. What are various implications of Mobil XHP continuity?
3. 0W20/5W20 which one? Brand? and cost
