Code P0023 Cadillac Description
Ignition voltage is supplied directly to the Camshaft Position Actuator Solenoid Valve. The ECM controls the solenoid valve by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.
The Diagnostic Trouble Code (DTC) will set when the ECM detects an open in the CMP actuator solenoid circuits for greater than 1 second or a cumulative of 5 seconds, when the solenoid is commanded OFF.

- Faulty Exhaust Camshaft Position Actuator Solenoid Valve Bank 2
- Exhaust Camshaft Position Actuator Solenoid Valve Bank 2 harness is open or shorted
- Exhaust Camshaft Position Actuator Solenoid Valve Bank 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
