    NOTE:
    • Properly locate the CMP actuator onto the locating pin of the camshaft.
    • The sprocket teeth and timing chain must mesh.
    • The camshaft and the crankshaft sprocket alignment marks MUST be aligned properly.
    • Do not use the CMP solenoid valve again. Install a NEW valve during assembly.
  9. Identify the alignment hole (1) in the rear face of the CMP actuator and the locating pin (2) on the front face of the camshaft.

    WARNING: Refer to Camshaft Position Actuator Removal and Installation Warning .
  10. Install the CMP actuator and timing chain. Align the hole in the rear face of the CMP actuator with the locating pin on the front face of the camshaft. If necessary, rotate the camshaft or crankshaft sprockets in order to align the timing marks. Use care to install the actuator completely onto the front of the camshaft. Position fingers onto the face of the actuator sprocket and push the actuator onto the front of the camshaft. Never push on the reluctor wheel when attempting to install the actuator.
