What does code P2328 mean?

Q: What does code P2328 mean?

Ignition Coil 'J' Primary Control Circuit High. P2328 means the engine computer (PCM) has detected a high-voltage condition on the primary control circuit for ignition coil 'J', which is the low-voltage side that the computer uses to switch the coil on and off. The circuit is monitored for expected voltage behavior, and a reading above the normal threshold for the commanded state sets this code.
