Most of the time, camshaft actuator codes are set due to dirt and debris getting clogged in the very fine screen on the actuator or being gummed up internally and not allowing movement. Sea Foam Motor Treatment or High Mileage can help clean the screen when added to engine oil @ 1 ounce of Sea Foam per quart of engine oil. Unfortunately, sometimes the actuators fail electronically. Sea Foam will not help in this situation.
