1998 Toyota Tacoma. Diagnosing and cleaning the MAF sensor.
Check engine light on: P0171 System Too Lean, Long term fuel trim at 35.1%, fuel trim should be below 10%.
When the air fuel ratio feedback is stable after engine warming up, he fuel trim is considerably in error on the RICH side
So I just cleaned the sensor with carb cleaner and brush.
Test drive for 45 miles, Oxygen sensor monitors cleared and no check engine light present.
Common Problems for P0171 Code
-Air intake (hose loose)
-Fuel line pressure
-Injector clogged
-Heated oxygen sensor malfunction
-Mass Air Flow Meter
-Engine coolant temperature sensor

I had a code Po420 before. I put a bottle of B12 Chemtool into the gas tank. After that, I had 2 codes, Po420 and Po171. After replacing the catalytic converter, Po420 gone and Po171 was still there. I followed this video on my Honda 2009 CRV last week. Cleared the code and drove 400 miles. Today I passed the smog test. Very happy.

I was working on 2000 Corolla with P0171 code. MAF sensor PASSED idle test for flow rate per manual, however examining one of the resistors under scope 10X magnification revealed broken wire (so cleaning would not help in this case). I pulled new one (on PYP) from 02(?) Echo. It fit Corolla setup and connector configuration (despite different connector angle) and fixed the problem!

Awesome "free" fix! I fixed my 4Runner the exact same way except I didn't clear the codes afterward. I just started it up and watched the STFT go really negative (-30) countering the long term of +30...after a short test drive the fuel trims were back to normal, and after a a couple short trips, the check engine light turned itself off so there was no need to complete the monitors over again. Cool channel man, keep it up. Merry Christmas!

Thank you for your comment. Since 2002 I have been using brake and carb cleaner. I'm still waiting on friends and family to complain on a bad MAF sensor because of a wrong cleaner I used on their car. I have done this on many different makes/models. Is brake/parts cleaner really that bad? My 2004 Camry, I cleaned the MAF sensor every year using brake or carb cleaner, it has 200K miles on it. Same with my 2002 Sienna, with 180K miles. I honestly never replaced the original Genuine Toyota MAF sensors. I guess you can say I'm lucky? I proved it with this video. Did you have a bad experience when you used a wrong cleaner?

@jr260551 7 жыл бұрын

Fix It Angel brake and part cleaner is not safe for plastic and rubber (if you've ever gotten it on a rubber caliper boot you'll know this) also it does leave a thin white film behind which can cause increased resistance within the maf resistors. Brake and part cleaner will probably work, but it's not the best cleaner to use. For $10, I would rather use the sensoclean that way you have no worries about damaging a $200 part.

I have replaced the spark plugs, spark plug wires/coils, and every filter I can think of. I’m the type of driver that does not have a heavy foot.
