Question about 2002 Toyota Tundra
I have already relace the two cat converters and 1 o2 sensor. this code seams to indicate a bad or dirty maf sensor. How hard is it to replace or should i just bring it to a mechanic?
P-0171 is a dirty Mass Air Flow sensor.
It is located in the intake air tube. Remove the wiring connector, and remove it from the intake. With a flashlight, examine the interior of the sensor. You will see 2 small wires with fuzzy stuff on them. This is your problem. The fuzzys are compromising the wire's ability to measure the air flow. Using a spray cleaner (throttle body or brake cleaner works best), spray the interior of the sensor until it is nice and clean. Do NOT use compressed air to clean it, you will damage the sensor. Replace it and plug it it, the light will go out shortly thereafter.
The graciousness of a FIxYa rating for this assistance would be greatly appreciated.
