Code P0024 Buick Description

The camshaft position actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. The camshaft position actuator solenoid signal from the ECM is Pulse Width Modulated (PWM). The ECM controls the camshaft position actuator solenoid duty cycle by controlling the amount of solenoid ON time. The camshaft position actuator solenoid controls the advance or the retard of each camshaft. The camshaft position actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts. The Diagnostic Trouble Code (DTC) will be set when the ECM detects the difference between the desired and actual camshaft position angle is greater than 5° for greater than 10 s.
