Q: What does code P2314 mean?

Ignition Coil 'E' Secondary Circuit. P2314 indicates that the powertrain control module (PCM) has detected a fault in the secondary circuit of ignition coil 'E', which is the high-voltage side that fires the spark plug. The PCM monitors the coil's secondary circuit for expected electrical behavior and sets this code when the signal is out of range, often due to an open or shorted coil, a bad plug, or wiring issues.
