Check the link above for more information. MAF replacement isn't difficult.

Code p0102


P0102 is a Mass air flow code. If you recently installed a K&N air filter it is possible some oil from the filter has gotten onto the sensor and damaged it. This code does not mean the sensor is faulty though. You could have an intake air leak which would also cause the code.

Trouble codes


Technical DescriptionMass Air Flow (MAF) Circuit Low Input
What does that mean?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). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

SymptomsYou will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.
CausesA 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)

I have a 2000 Chevy venture and recently about 6 months ago had the transmission overhauled and now I have code p0742 showing up. Could it be replacing the water pump and fuel pump be causing the code...


Hello: P0742 MEANS THE TORQUE converter clutch is stuck on. The repairs on the water pump and fuel pump should not have caused this. The P0742 could be caused by electrical connection going into the transmission, a dirty/failed torque converter solenoid, debris in the transmission. Recommend you get code cleared at Auto Zone, O'Riely, Advance Auto (they probably won't charge you) and see if code comes back, it may only be a one time incident. If it comes back then it will need to be repaired. How long is the warranty on the trans overhaul, time? miles?
