Hi, recently change my maf sensor and my connector. Its a 09 LNF, Injen CAI, zzp intercooler, zzp pcm.
The issue is that my new maf do not read anything, I checked for bad wire or smething and I haven’t noticed anything. Grounds are good. I looked for the schematic and I hooked it up by the schematic. If anybody knows the pin with the colors of the original schematics and also the voltage I should have. The car runs fine when I drive it normally, WOT is where it runs like a piece of crap. The boost jump between 23 and drop to 15-16. I got P0100, P0102, P0103 and something about the intake temp. I have an OBD2 wich I can read live data, my intake temp is at -40 C and the maf read 86.7 lb/min. Sure it is false. If anybody experience this or can give me more info about this. Thanks a lot. Cobalt SS 2009 LNF.
