The automobile fault code P2309 indicates a problem with the ignition coil circuit.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour. Other factors that may influence the cost include the make and model of the vehicle, the severity of the issue, and the availability of replacement parts.

The P2309 code is related to the ignition system of the automobile.

It indicates a problem with the primary control circuit of ignition coil ‘D’. The Powertrain Control Module (PCM) controls the current flow through the primary ignition coil.

The PCM detects a short to voltage in the circuit and sets the P2309 code. This code can cause issues with the spark plug firing and should be addressed promptly.

What are the possible causes of the P2309 automobile fault code?
