What does P0351 mean?
Diagnostic Trouble Code (DTC) P0351 stands for “Ignition Coil ‘A’ Primary/Secondary Circuit.” It indicates that there’s a potential problem with the cylinder #1 ignition coil or its circuit. Every ignition coil has a “primary” winding and a “secondary” winding.
What causes a p0351 code on a cop?
Potential causes of a P0351 code include: Short to voltage or ground on COP driver circuit Loose connection at coil or broken connector locks Is the engine misfiring presently? If not, the problem is likely intermittent. Try wiggle testing the wiring at the #1 coil and along the wiring harness to the PCM.
What are the symptoms of a p0351 DTC?
Symptoms of a P0351 DTC may include: MIL (Malfunction indicator lamp) illumination Engine misfire may be present or intermittent Potential causes of a P0351 code include: Short to voltage or ground on COP driver circuit Loose connection at coil or broken connector locks
Where can I find the OBD2 code for a Dodge?
Check specific manufacturer pages on the site, as some of them, we list the OBD2 codes on those pages for those specific vehicles. . Engine control module (ECM) -RAM read/ write error
What causes a DTC p0351 ignition coil to set?
If an open or a short is detected in the driver circuit for coil number 1, a P0351 may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also. Symptoms of a P0351 DTC may include: Potential causes of a P0351 code include: Short to voltage or ground on COP driver circuit
How much does it cost to diagnose a p0351 code?
The cost of diagnosing the P0351 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. When is the P0351 code detected? Each ignition circuit is continuously monitored by the Engine Control Module (ECM).
What does p0351 mean in the ignition system?
P0351 Meaning 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.

How to repair a DTC p0352 ignition coil?
If there is no voltage on the driver circuit, then turn the ignition off. Disconnect the PCM connector and check the continuity of the driver between the PCM and the coil. If there is no continuity repair the open or short to ground in the circuit. If continuity is present, then check for resistance between ground and the ignition coil connector.
