Fault Code "No Bus"
I have a 2000 Dodge 1500 Ram Van with 5.2. I have recently changed plugs, distributer cap and rotor. Van started to cut out at idle and finally threw a fault code for the AIC which I replaced. Van ran like crap and was throwing all kinds of fault codes. Took to Firestone and they said it is the pcm. But with some research I found that some sensors can do this so i start checking sensors. Upon looking around I find that a wire coming out of the pcm is sitting on a hose clamp and notice that it has worn through the insulation and bare wire is making contact with hose clamp. So I move and wrap with electrical tape and figure problem solved. Nope!Ran great for a day but then it was hot out and humid, it started backfiring and not able to keep running. Then all of a sudden the odometer starts flashing and then No Bus. I have checked the Crank Sensor, the Camshaft sensor, MAP sensor, Throttle Position Sensor, and they all have 5v on the reference wire. All the sensors appear to be functioning as they should. But one thing that I did notice is that when I have the sensors unplugged and check the signal wire I also get 5v on the above sensors. So what that is telling me is that I am getting power on the signal wire when its not connected to the sensor. So I am asking is this right? Or is this telling me that indeed the pcm is shot and shorted out thus the 5v on the signal wires. Can anyone confirm that?
