It would be nice to know what year make and model of vehicle this is on. Your vehicle probably has VVT (variable valve timing) and this error is present when the cam shaft is not in the proper state according to other factors. The process is controlled by a solenoid and oil pressure. You could try removing the valve and checking the filter screen and the actual function or you could risk just replacing it. Since you did not post the vehicle info though it is a risk
