What Does P2310 Mean?
The PCM has detected an abnormally high voltage condition in the primary control circuit for ignition coil D. This indicates an open circuit in the wiring, connector, coil, or PCM driver circuit.
Common Causes
35%
Open circuit in primary control wire between PCM and coil D
30%
Failed ignition coil D with open primary winding
20%
Corroded or disconnected connector at coil D or PCM
15%
Failed PCM ignition coil driver circuit open internally
Diagnostic Steps
1
Step 1: Inspect ignition coil D connector and PCM connector for corrosion, damage, or loose fit
2
Step 2: Test continuity of control wire from PCM to ignition coil D connector
3
Step 3: Check primary winding resistance in ignition coil D and compare to specifications
4
Step 4: Verify power supply and ground circuits to coil D are functioning properly
5
Step 5: If all circuits and coil test within specs, suspect PCM driver circuit failure
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The PCM has detected an abnormally high voltage condition in the primary control circuit for ignition coil D. This indicates an open circuit in the wiring, connector, coil, or PCM driver circuit.
The most common cause of P2310 (Ignition Coil "D" Primary Control Circuit High) is: Open circuit in primary control wire between PCM and coil D
Typical repair costs for P2310 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cylinder D will not fire resulting in significant power loss and rough running. Can cause catalytic converter damage and increased emissions if driven with active misfire.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2310 to identify the root cause.
