CUSTOMER CONCERN Customer states warning lights come on intermittently. DTCs C0561-71 and P0011 are stored. CAUSE Oil-condition and actuator-circuit testing confirmed the intake camshaft position actuator solenoid was not controlling cam timing correctly. CORRECTION Remove and replace intake camshaft position actuator solenoid. Clear DTCs C0561-71 and P0011 and verify commanded and actual camshaft positions agree.
