The fault code is P2312.

The estimated repair time is 1.0 hour. The cost of fixing the fault code depends on the repair time.

Most auto repair shops charge between $75 and $150 per hour.

Therefore, the fixing cost of P2312 can range from $75 to $150.

The P2312 code is related to the ignition system of the automobile. It indicates a problem with the primary control circuit of ignition coil ‘E’. The Powertrain Control Module (PCM) controls the current flow through the primary ignition coil.

The PCM detects a short to voltage in the circuit, which triggers the P2312 code.

This code can cause issues with the spark plug firing and should be addressed promptly.

What are the possible causes of the P2312 automobile fault code?

If you’re experiencing a rough running engine and the engine light is on, it could be due to the P2312 fault code.
