Problem: Cam advance DTCs present (p0011 p0021 p0300). Car runs poorly with hesitation issues.
Solution: Make sure the variable cam solenoid connectors are not backwards. If they are in the correct position, open the solenoids and make sure there is no debris. Any foreign debris will prevent full movement potentially causing the issue. Remove any debris present and the solenoids should function properly.
- Note: If the heads or block are machined, it can throw the centering of the cam advance solenoids out of whack, not allowing them to operate correctly. When the cam solenoid covers are modified to center the assemblies correctly, the cam advance and engine should operate as intended.
