The Camshaft Position Sensor (CMP) on the 4.7L V - 8 engine is bolted to the front/top of the right cylinder head CMP Location - 4.7L Engine


It is easier to remove/install sensor from under vehicle.

  1. Raise and support vehicle.
  2. Disconnect electrical connector at CMP sensor CMP Location - 4.7L Engine
  3. Remove sensor mounting bolt CMP Location - 4.7L Engine
  4. Carefully pry sensor from cylinder head in a rocking action with two small screwdrivers.
  5. Check condition of sensor o-ring.


  1. Clean out machined hole in cylinder head.
  2. Apply a small amount of engine oil to sensor o-ring.
  3. Install sensor into cylinder head with a slight rocking action. Do not twist sensor into position as damage to o-ring may result
