Why does my Ford Escape have a p0012?
With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0012.
