2013 GMC Yukon P0010 VVT Fault: Recurring Code After Solenoid Replacement
The engine light activated on my 2013 GMC Yukon, prompting a visit to the dealership. Diagnostics revealed code P0010, indicating an issue with the Variable Valve Timing (VVT) system. The dealer replaced the VVT solenoid/actuator at a cost of approximately $700. After returning the vehicle, the engine light reappeared and the same P0010 code was detected during On-Star diagnostics. The dealership now suggests a potential timing belt failure or camshaft 'walking,' recommending a full engine removal to investigate. I declined this recommendation and returned the vehicle with the engine light still active and the P0010 code persisting. The vehicle runs smoothly under normal conditions, but the recurring fault code is concerning. What should I do next? Is there a more reliable diagnostic path or component that could be at fault? Thank you for any insights.
First, the dealer should provide a guarantee on this recurring P0010 error — repeated misdiagnosis is a valid concern. Consider getting an independent diagnostic from a reputable auto shop to verify the root cause. Code P0010 may indicate one or more of the following: - Faulty Oil Control Valve (OCV) - Open or short in the VVT/VCT circuit - Open or short in the OCV or solenoid valve - Damaged Powertrain Control Module (PCM) For detailed information, see: https://www.autozone.com/p0010-meaning-and-causes
