Are there any problems with the Chevrolet HHR engine?
Are there any problems with the Chevrolet HHR engine? CEL, CODE P-001. REPLACED BOTH CAM POSITION ACTUATORS (ONLY 1 WAS BAD). NO CEL AND CAR RUNS GREAT. Check engine light came on indicating bad exhaust fuel purge solenoid. Replaced both exhaust and intake solenoids. Key in ignition switch could not be removed, and would not turn to shut the engine off. What are DTC codes for Chevrolet HHR engine problems? Also serviced transmission while it was there. Replaced water pump, thermostat, radiator cap (water pump was functional but leaking). DTC codes p0221 and p0121, throttle position sensors. still in process...
