2010 Chevrolet Equinox P0011 and P0016 Error Codes: Diagnosis and Solutions for 2.4L Ecotec Engine
I'm experiencing persistent check engine light issues on my 2010 Chevrolet Equinox with a 2.4L Ecotec engine, showing trouble codes P0011 and P0016. I've already replaced the camshaft position sensor and the variable valve timing (VVT) intake sensor, but the check engine light remains on. While the vehicle runs smoothly under normal conditions, I notice elevated RPMs during gear shifts and difficulty maintaining consistent engine speed while driving. Could these codes be related to camshaft phasing or actuator malfunction? Any technical insights or recommended next steps would be greatly appreciated.
Since you've already replaced the cam sensor and VVT intake sensor, it's worth trying a bottle of RISOLINE oil treatment to help dissolve any oil-based deposits that may be affecting internal components. Ensure your oil maintenance schedule is up to date. If the issue persists, inspect the wiring harnesses connected to the actuator and verify camshaft timing alignment. For reference: OBD-II code P0011 indicates a camshaft position sensor or actuator malfunction, while P0016 points to an issue with the variable valve timing system.
