Camshaft Position Sensor: Service Precautions
CAUTION:^ Once the engine is aligned at TDC, do not move the crankshaft until the entire procedure is complete. Doing so will result in the fuel system being out of time with the engine, causing a possible emissions fault.
^ A special tool must be used during the installation of the replacement synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
^ It is very important to coat the gear on the camshaft synchronizer with Super Premium SAE-5W-30 Motor Oil XO-5W30-DSP or equivalent meeting Ford specification WSS-M2C153-G. Failure to do so could result in gear failure.
