A mechanic may diagnose this trouble code by starting with the ignition coil(s). The mechanic would test all ignition coils using the manufacturer’s recommended procedure. After any and all ignition coils have been tested, the mechanic would check for wiring issues from the ignition coil to the powertrain control module. This would include any frays, cracks, breaks, or corrosion that may exist within the circuit. Finally, the mechanic would test the powertrain control module with a high tech scan tool in order to ensure it is functioning properly. After all tests have been carried out, the mechanic would relay all information he/she found with the customer to make an informed repair decision.
A common mistake when diagnosing this trouble code would be to try any ignition coil testing with the engine running. This is a novice mistake but can still happen. Ensure that the engine is off during ignition coil and powertrain control module testing to avoid personal injury from shock or potential damage to your vehicle.
This code would be considered serious because it can cause major drivability issues. This code being stored in your vehicle’s powertrain control module can cause it to have a really hard time getting around. It will be hard to obtain speed particularly when going up hills. It would be a good choice to have this issue diagnosed and repaired at the earliest possible opportunity.
Repairs that can potentially resolve the issues caused by this trouble code would include:
Replacing one or all of the ignition coils on the engine
Repairing or replacing wiring or connectors that are associated with the ignition coil to powertrain control module circuit
