Description and Operation 1-129
Variable Camshaft Timing (VCT) Monitor
Variable Camshaft Timing (VCT) Monitor
The VCT output driver in the powertrain control module (PCM) is checked electrically for opens or shorts. The VCT system is checked functionally by monitoring the closed loop camshaft position error correction. If the correct camshaft position cannot be maintained and the system has an advance or retard error greater than the calibrated threshold, a VCT control concern is indicated.
For additional information, refer to Variable Camshaft Timing (VCT) System in this section.
