When it comes to Dodge vehicles, P0351 is an ignition coil code that can be caused by various issues. This code indicates that there is a malfunction in the Ignition Coil No. 1, 2 or 3 Primary Circuit, and the PCM detected that the peak coil current was not reached in 2.5 ms of dwell for 3-6 seconds. A common symptom of this issue is engine cranking or running when the ASD relay is on, and the system voltage is over 10v. The coil primary resistance must also be less than 2 ohms. Possible causes of this issue include an open ASD relay power circuit to the ignition coil, an open or grounded Ignition Coil No. 1, 2 or 3 primary “driver” circuit, damage to the Ignition Coil No. 1, 2 or 3, or a failed PCM.
Causes and Solutions for Dodge Code P0351
| Cause | Solution |
|---|---|
| Open ASD relay power circuit to the ignition coil | Check the ASD relay power circuit for any signs of damage or corrosion. |
| Open or grounded Ignition Coil No. 1, 2 or 3 primary “driver” circuit | Look for any broken wires or an open fuse in the circuit. |
| Damage to the Ignition Coil No. 1, 2 or 3 | Replace the damaged ignition coil. |
| Failed PCM | Replace the PCM. |
Open ASD Relay Power Circuit to the Ignition Coil
The open ASD relay power circuit to the ignition coil is a common cause of Dodge Code P0351. The first step to solve this issue is to check the ASD relay power circuit for any signs of damage or corrosion. The wires should be intact and free from any signs of wear and tear. If any damage is found, the damaged wires should be replaced as soon as possible.
Open or Grounded Ignition Coil No. 1, 2 or 3 Primary “Driver” Circuit
Another possible cause of Dodge Code P0351 is an open or grounded Ignition Coil No. 1, 2 or 3 primary “driver” circuit. To solve this issue, the circuit should be inspected for any broken wires or an open fuse. If any of these problems are detected, the faulty wiring or the open fuse should be replaced immediately.
Damage to the Ignition Coil No. 1, 2 or 3
If the Ignition Coil No. 1, 2 or 3 is damaged, it can cause Dodge Code P0351. If this is the case, the damaged ignition coil should be replaced as soon as possible. The new ignition coil should be installed correctly and tested to ensure that the issue is resolved.
Failed PCM
The final possible cause of Dodge Code P0351 is a failed PCM. If the PCM is faulty, it must be replaced as soon as possible. The new PCM should be installed correctly and tested to ensure that the issue is resolved.
Conclusion: Resolving Dodge Code P0351
Dodge Code P0351 is an ignition coil code that can be caused by various issues. The possible causes of this issue include an open ASD relay power circuit to the ignition coil, an open or grounded Ignition Coil No. 1, 2 or 3 primary “driver” circuit, damage to the Ignition Coil No. 1, 2 or 3, or a failed PCM. If any of these issues are detected, it is important to take the necessary steps to resolve the issue. By following the solutions outlined in this article, you can successfully resolve Dodge Code P0351 and get your vehicle running smoothly again.
