Definition. Error Code P1391 happens when the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) has detected that the actual position of the CMP disagrees with its expected level as set by the manufacturer.
Why is my PCM getting a weak CKP signal?
Open or shorted CKP sensor harness Poor electrical connection in the CKP sensor Stretched or jumped timing belt or chain Open or shorted CMP sensor harness Poor electrical connection in the CMP sensor This could also happen if the coils and injectors are getting fired intermittently. Something you would expect if the PCM is getting a weak signal.
How much does it cost to repair a p1391 Jeep?
The cost of diagnosing the P1391 JEEP code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. The Engine Control Module ( ECM) detected the actual Camshaft Position Sensor (CMP) position disagreed with the expected CMP level.
