No Bus - No Start
I have the following codes along with No Bus in the dash. Under this condition the 2000 Ram SLT will not start. I have the entire front of the engine off as I'm fixing a timing cover gasket leak but know the ECM threw the following codes...
P0202 P0132 P0207 Anyone with any insight? |

An O2 sensor code, and two injector circuit codes.

You have a wiring issue or the PCM is shot...

The dodge system is kinda strange...... it's basically a small computer network in your truck. PCM talks to CTM (central timer module, essentially a network switch) which talks to the cluster, etc. If one of your five volt sensors is failing, the PCM gets confused, and stops talking. To anything. Hence, no bus.
Supposedly, you can find the failing sensor by unplugging them one at a time, until the cluster starts working again. Of course, with some sensors unplugged, it's likely the engine won't run anyway. Timing cover gasket has nothing to do with PCM, nor would it be responsible for low compression. You have several problems you are fighting. |
