Does anyone know, or can anybody check what the voltage on C1 Pin8 on the PCM is at idle? I am trying to figure out if the ecm modifies the CKP sensor signal or if it just sends the same signal. I suspected I had a bad ECM and I sent it out for a rebuild from auto computer specialist and they did a full rebuild but I’m still having the same issues. I replaced the CKP sensor a few years ago due to the tach dropping out and a no start issue but I couldn’t get a cummins part so I used an eichlin sensor. When I hooked up a scan tool I had CKP signal and CMP signal but no engine speed at the PCM. For testing purposes could I jump the signal wire from the CKP sensor to the engine speed input for the PCM? At that point if I don’t have engine speed would that be a bad PCM? It’s a replacement unit from car computer exchange from less than a year ago.
