EGR C Control Circuit Low. P23E3 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the exhaust gas recirculation (EGR) valve 'C'. This typically means the circuit is shorted to ground or the EGR valve solenoid has failed, preventing the PCM from properly commanding the valve.
