P0351 JEEP - Ignition Coil 1 Circuit
- Ignition Coil 1 harness is open or shorted
- Ignition Coil 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
- Lack/Loss of Power
- Engine may be harder to start
- Engine hesitation
- Rough engine idle
The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module (ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.
where is the ignition coil located...
Does the P0351 mean that there is a problem with the ECM (since it is not a coil pack)...
Msd coil po351 code...
Any information is appreciated. Thanks
