2011 Chevrolet Malibu P0014 and P0420 Codes: Camshaft Solenoid Replacement & Diesel-Like Noise Diagnosis
My 2011 Chevrolet Malibu is displaying diagnostic trouble codes P0014 and P0420. The engine makes a ticking noise at idle and sounds similar to a diesel during acceleration. Auto Zone's scanner indicates that the most likely fix is replacing the camshaft position adjuster solenoid. I'm wondering if this is sufficient or if I should visit a dealership for a more comprehensive diagnosis. Any insights from owners with similar issues? Thanks.
My vehicle has passed the powertrain warranty at 104,116 miles and is now outside manufacturer coverage.
