MAF Fault code P0102 short/open circuit

[jhshelton]

Replaced the MAF and still get the short/open circuit fault in Durametric.

 

My question is how to trace the short/open circuit. Is this tied to the ignition switch as well?

 

Thanks again for all of the advise.

Usually, P0102 is a wiring break or short, and you should be checking the wiring from the MAF to the DME (where it gets its power), not the ignition switch.

JFP, Thanks! Greatly appreciated

I would start by checking the voltage to the MAF sensor first.  Disconnect the wire and put the ignition key on, check voltage.  If none, check the wiring harness connections on the right side of the engine compartment.  Disconnect them and clean with electrical cleaner.

^This and also check the MAF voltage reading using the Durametric. Should be around 1.1v with key on engine off and 1.3v at idle (engine hot).
