P1336 is that the correlation between the ckp and cmp are fkd. So start with checking the wires going to the crank and cam sensor. Like i said earlier if u change one change the other. If the problem persist start by checking the harness and connectors to the sensors. Worst case could be jumped timing. Start with the simple ones. Crank sensor is located by the damper, which if i remember correctly needs to be removed to get to it. The other the cam sensor is located by the power steering pump.
