How does a mechanic diagnose the P2327 code?

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.

Rodrigo was exactly on time, very professional and friendly. He assessed my car, let me know the exact problem when a previous mechanic from a shop in my area was unable to. I felt he was very honest and sincere letting me know the level of urgency that I deal with the issue. Absolutely no pressure. I will absolutely use Rodrigo the next time I need anything to do with my car and will tell everyone about him. This is such a great service, I will never go to another mechanic again. It is so convenient. I couldn’t be happier. :)
