I don't think you need to reset the ECU when installing a MAF. If the CEL is on you can reset that with a OBD2 scanner.

When I replaced it, the car did not seem to reconize the replacement. I was told I have to have the "computer" reset. So is that the ECU they are talking about.


I would make sure you have the correct part.


You could disconnect the car battery for a couple of minutes and see if it does any good but you will probably lose codes and settings that you may not want to.


So, I shouldn't have to reset anything to replace MAS??


What exactly is the problem? Does the car drive?

We had the car diagnosed. Mass airflow sensor, ok. I bought a new one put it on, same thing. Put the old on back on after cleaning it out. This corrected the problem for almost a year but the same problem is starting back so I need to get the new one in.

We were told that the parameters needed to be reset once the old one was not correct.


There is no reset. But you need to do a idle relearn/reset procedure.... t442597.html

Thank you so much!


Try the Idle Air volume relearn as well. Search online for the procedure.
