How severe is this DTC?

When a P2308 is stored, the cause should be diagnosed as soon as possible. The symptoms that likely accompany these codes will generally require immediate attention.

What are some of the symptoms of the code?

Symptoms of a P2308 fault code may include:

• Engine misfires
• Decreased engine performance
• Reduced fuel efficiency
• Other related codes
• Fuel injector operation for the affected cylinder may be disabled by the PCM

What are some common causes of the code?

Causes

of this code may include:

• Bad spark plug wire or boot
• Faulty relay or blown fuse (fuse link)
• Open or shorted wiring or wiring connectors (damage from wildlife)
• Faulty ignition coil
• Defective camshaft or crankshaft sensor or wiring

What are the troubleshooting steps for P2308?

You will need a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable source of vehicle information to accurately diagnose a P2308 code.

You can save time and trouble by searching for Technical Service Bulletins (TSBs) that match the stored code, the vehicle (year, make, model, and engine), and the symptoms presented. This information can be found in your vehicle information source. If you find the right TSB, it might provide a quick solution to your diagnosis.

After connecting the scanner to the vehicle’s diagnostic port and retrieving all stored codes and relevant freeze frame data, note the information (in case the code turns out to be intermittent). After that, clear the codes and test the vehicle until one of two things happens; the code is restored or the PCM enters readiness mode.

The code may be more difficult to diagnose if the PCM enters readiness mode at this point, as the code is intermittent. The condition that caused the P2308 to be stored may need to worsen before an accurate diagnosis can be made. If the code is restored, proceed with the diagnosis.

You can obtain connector face views, connector pinout charts, component location diagrams, wiring diagrams, and diagnostic flowcharts (related to the code and the vehicle in question) using your vehicle information source.

Perform a visual inspection of the associated wiring and connectors. Repair or replace wiring that has been cut, burned, or damaged. Scheduled maintenance includes replacing spark plug wires and boots. If the vehicle in question is beyond the recommended maintenance interval for a tune-up, suspect bad ignition wires/boots as the cause of a stored P2308.

Spark plug boots that are torn, burned, or contaminated with fluid should be considered faulty. Access the junction between the ignition coil and the spark plug wire. Check for high-energy ignition (HEI) at the spark plug. If none is detected, disconnect the spark plug wire from the coil and see if there is HEI there. If there is HEI at the spark plug, suspect a faulty spark plug or a PCM error. If there is no HEI at the spark plug but it is strong at the coil, suspect a bad spark plug wire or boot. If there is no HEI at the coil, suspect a faulty coil. HEI should be tested (carefully) with the engine running.

When a P2309 is stored, the cause must be diagnosed as soon as possible. The symptoms that likely accompany these codes will generally require immediate attention.

What are some of the symptoms of the code?

• Engine misfires
• Decreased engine performance
• Reduced energy efficiency
• Other related codes
• Fuel injector operation for the affected cylinder may be disabled by the PCM

What are some common causes of the code?

Causes

of this code may include:

• Faulty relay or blown fuse (fuse link)
• PCM failure
• Open or shorted wiring or wiring connectors (damage caused by wildlife)
• Faulty ignition coil
• Faulty camshaft or crankshaft sensor or wiring

What are the troubleshooting steps for P2309?

You will need a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable source of vehicle information to accurately diagnose a P2309 code.

You can save yourself time and trouble by searching for Technical Service Bulletins (TSBs) that match the recorded code, the vehicle (year, make, model, and engine), and the symptoms presented. This information can be found in your vehicle information source. If you find the right TSB, it might provide a quick solution to your diagnosis.

You can obtain connector face views, connector pinout charts, component location diagrams, wiring diagrams, and diagnostic flowcharts (related to the code and vehicle in question) using your vehicle information source.

Perform a visual inspection of the associated wiring and connectors. Repair or replace wiring that has been cut, burned, or damaged. Wiring on top of the engine is often damaged by wildlife trying to stay warm in cold climates.

Use the DVOM to test the voltage and ground circuits at the ignition coil in question. If no voltage is detected, check the system relay and associated fuses. Replace faulty relays and/or blown (or otherwise defective) fuses as needed.

If voltage and ground are detected at the coil, test the ground circuit corresponding to the PCM connector with the engine running. If a ground pulse is detected there, suspect an open circuit between the coil in question and the PCM. If no ground pulse is found there, suspect a faulty PCM or a programming error.
