Crankshaft Position (CKP) Sensor - 2.0L GTDI

Special Tool(s)

Ford Taurus. Engine

Removal

NOTICE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.

  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02.
  1. Remove the RH fender splash shield. For additional information, refer to Section 501-02.

    Ford Taurus. Engine

  1. NOTE: Turn the engine in the normal direction of rotation only.

    Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the TDC marked tooth on the crankshaft pulley (located on the 20th tooth counterclockwise from the missing tooth) at the 6 o'clock position.

    NOTE: The engine front cover is shown removed in graphic for clarity.

    Slowly rotate the crankshaft clockwise until the crankshaft contacts the Crankshaft TDC Timing Peg.
    Special Tool(s): Timing Peg, Crankshaft TDC 303-507.
