Camshaft Position B - Actuator Circuit (Bank 2)
P0023 is the OBD-II generic code indicating the Engine Control Module (ECM) has determined that the bank 2 exhaust camshaft Oil Control Valve (OCV) has an open or short circuit. This happens during one drive cycle.
Note: Symptoms may change depending on the timing positions of the camshaft.
Visually inspects the wiring and connections at the OCV and the ECM
Scans the computer for trouble codes and documents freeze frame data to see when the failure happened
Retests the vehicle to see if the P0023 code comes back
Checks the OCV for the correct resistance to see if the valve is shorted or opened internally
Checks the wiring from the ECM to the OCV for open or short circuits
Performs a manufacturer's specific pinpoint test for the P0023 code and repairs as needed if the code returns
Note: Follow the manufacturer's recommended pinpoint test to narrow down the problem; each engine may be tested differently and possible engine internal damage may occur if tests are not performed in accordance with a correct procedure.
Follow these simple guidelines to prevent mistakes:
The engine may run rough and stall.
The engine's fuel consumption may get worse and the engine may get carbon fouling of internal valve components.
Driving the vehicle for prolonged time with the circuit shorted may damage the ECM.
The code's P0023 problems can happen when the OCV connector has corrosion that will act like an open circuit in the valve. The wiring to the sensor, if broken or shorted, can cause the code.
