Sounds like a vacuum leak. Do you hear a sucking sound? Check your vacuum hoses, around the throttle body and intake for the sound. p0102 can come on when there is unmetered air getting to the engine and it could be fluctuating because the idle air control valve is trying to compensate.

98 gran prix p0102 obd code


P0102 - Mass Air Flow (MAF) Circuit Low Input
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow).
A code P0102 may mean that one or more of the following has happened:
  • The MAF may be disconnected, or a wiring connection may be bad
  • The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
  • The MAF sensor may be faulty
  • The vehicle computer may be faulty (very rare)
Contact us if you need additional details. Good luck.

P0102 code on a 2000 Buick Park Avenue is this the code for a "mass air flow sensor"


yes your right. it is a low circuit input code for a mass air flow sensor. you can try taking the mass air off and cleaning it good. sometimes it will help but normally they are just bad.

What does a P0102 code mean?


P0102 - Mass Airflow Circuit Low Input

Check to make sure the mass air flow sensor is plugged in and has a good connection. Do you happen to use a re-usable air filter such as a K&N? Often times when people recharge the re-usable filters they use too much oil which causes the the MAF sensor element to get dirty. Sometimes removing the sensor and cleaning the element very carefully with electronics cleaner can fix the problem.

By the way, the mass air sensor is mounted between the intake tube and air filter usually.
