Q: What does code P23E2 mean?

EGR C Control Circuit Performance. P23E2 indicates that the powertrain control module (PCM) has detected a performance fault in the control circuit for the exhaust gas recirculation (EGR) valve on 'C' circuit, meaning the electrical command to the valve is not producing the expected response. The PCM monitors the circuit for opens, shorts, or a stuck valve and sets this code when the circuit's behavior falls outside the programmed parameters.
