Jan 24, 2011 - Hey guys, I'm working on a 97 3500 that's had the bed removed and replaced with a flatbed. There is the biggest mess under that truck wiring wise and. ... 2007 Ram 3500 A/C compressor wont engage, need wiring diagram ...
you have codes related to the pcm, transfer pump and a vehicle speed sensor. these could be related or all individual issues. related issued could be wiring, untill you start doing testing it will be hard to tell. start cheap and test the speed sensor first, then you can clear the codes and continue on any codes come back.
Disconnect the PCM harness connector(s). Disconnect the Vehicle Speed Sensor harness connector. Note: Check connectors - Clean/repair as necessary. Measure the resistance of the 5 Volt Supply circuit between the VSS harness connector and the PCM harness connector. Is the resistance above 5.0 ohms?
