The fault code P2304 indicates an issue with the ignition coil circuit.

The diagnosis involves checking the wiring and connections, as well as testing the ignition coil and related components.

The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the hourly rate of the auto repair shop, which typically ranges between $75 and $150 per hour.

Other factors that may influence the cost include the need for replacement parts and any additional repairs that may be required.

The P2304 code is related to the ignition system of the automobile.

It indicates a problem with the primary control circuit of ignition coil ‘B’. 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 P2304 code.

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

What are the possible causes of the P2304 automobile fault code?

If you’re experiencing a rough running engine and the engine light is on, it could be due to the P2304 fault code. This code is often caused by a faulty ignition coil ‘B’, an open or shorted harness, or a poor electrical connection in the ignition coil circuit. To fix the issue, it’s recommended to visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can I visually inspect the related wiring harness and connectors for the P2304 fault code?

To visually inspect the related wiring harness and connectors for the P2304 fault code, first check for the symptom of the engine light being on or the service engine soon warning light. If the engine is running rough, it may be caused by a faulty ignition coil ‘B’, an open or shorted ignition coil ‘B’ harness, or a poor electrical connection in the ignition coil ‘B’ circuit. To fix this issue, check the possible causes listed above and visually inspect the related wiring harness and connectors for any damaged components or broken, bent, pushed out, or corroded connector’s pins.
