DTC P0016 is set when the actual intake camshaft position is retarded beyond the reference value. This condition may be caused by incorrect mechanical timing.
Item | Detecting Condition | Possible Cause | |
DTC Strategy | Case 1 |
•
Intake camshaft edge in CVVT full retard position out of range compared to reference position. | 1. Poor Connector Connection 2. Incorrect Valve Timing 3. Defected Oil Control Valve 4. Defected Cam Phaser 5. Defected Intake CVVT Assembly |
Case 2 |
•
Alignment between the camshaft and crankshaft is off by one or more cam/crank sprocket cogs. | ||
Enable Condition | Case 1 |
•
