SOURCE: having problems with my 96 chevy tahoe mass air flow

The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

SOURCE: mass air flow sensor

The mass airflow sensor is very important...it uses tiny diodes mounted in the flow path of the incoming air to the throttle body in units called CFM. It sends that information to the engine computer and the program calculates the proper amount of fuel needed to mix with the volume of air coming in. It is vital to your car that this sensor is properly maintained. If it's diodes are allowed to get dirty such as by having a dirty air filter, then the readings it takes will be inaccurate and the cars' performance will suffer. If the diodes break, you will not be able to drive the car and a new sensor is expensive.
DO NOT buy into snake-oil products like MAF cleaner...it is an expensive gimmick plus spraying anything under pressure into the sensor can break the diode filaments, some of them are barely .010" thick. Just remove the sensor with the proper bit and carefully poor a stream of isopropyl alcohol (isohol, rubbing alcohol) over the diodes until they shine. Then rinse with water and let air dry.

SOURCE: where is mass air flow sensor located on 2002

The mass air flow (MAF) sensor is an integral part of the throttle body assembly and cannot be serviced separately. For replacement of the MAF sensor refer to Throttle Body Assembly Replacement.

SOURCE: 98 chevy suburban, code reads mass air flow sensor

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.

Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

I am getting p0030 , p0036. po102 and p0443 on my 2007 chevy uplander ,


I think the first thing I would do is clear the codes and see how many come back after you drive it.
Code 30 and 36 are for the heater circuit in the O2 sensors on bank one. I doubt it would be both sensors, so it may be a wiring problem.
Code 102 is for a low signal from the mass air flow meter which could also be a wiring problem or the sensor or a dirty air filter.
Code 443 is for a problem with the evap purge solenoid circuit which again could be a wiring problem or the solenoid.
