The engine light came on in my 2014 Chevy Equinox AWD. The research said P0010 and P0011, i.e., the camshaft. The dealer changed the shafts and advocated an engine flush. If I do as the dealer advocates or are they simply hoping to get $200 out my pocket because the camshaft was covered under my extended warranty? — Luther
Your engine’s camshafts are able to change positions, progressing under acceleration. This system is referred to as Variable Valve Timing (VVT) and leads to a superior driving experience and decreased emissions. Replacing the camshafts in your Equinox is a somewhat major fix that’s not common. The normal fix for codes P0010 and P0011 would be to substitute one or both of the camshaft actuator solenoids (CMP), which are small electronics that control oil flow.
Your vehicle’s most important computer energizes these solenoids under different driving conditions, allowing high-pressure engine to enter in the VVT system, thus facilitating the shift in camshaft position. I know it’s confusing, but what you really need to be aware of is that because these solenoids have oil passing through them, GM believed it would be beneficial to integrate a tiny filtering display on them. These displays gradually get plugged, reducing the oil pressure, finally triggering code P0010. The oil flush has been recommended because if the displays are plugged, then it’s very likely that the remaining portion of the engine must also be contaminated.
