I'm diagnosing a P0113 code on a G6 3.5 and looking for the pin with 5v. My choices are.
Pin A MAF sensor signal
Pin B Ignition voltage
Pin C GROUND
Pin D IAT sensor signal
Pin E Low Reference
Looking for the 5v at the wire connector end to rule out a bad PCM. If I connect a multimeter, black lead to ground and red lead to 5v pin if I get no volts is my PCM bad? Is this test done KOEO? Thanks for the video.
