Q: What does code P2CE2 mean?

Intake Air Heater C Circuit Range/Performance. P2CE2 indicates that the powertrain control module (PCM) has detected an out-of-range or performance fault in the intake air heater circuit 'C', which is one of several heating elements used to warm incoming air on diesel engines during cold starts. The PCM monitors the circuit's electrical behavior and compares it to expected values, setting this code when the signal falls outside the manufacturer's specified range or fails a rationality check.
