Crankshaft Position Sensor: Service and Repair

Crankshaft Position (CKP) Sensor - 2.0L GTDI





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.

2. Remove the RH fender splash shield.

3. Loosen the 4 retainers and remove the underbody shield.





4. NOTE: Turn the engine in the normal direction of rotation only.
Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the Top Dead Center (TDC) marked tooth on the crankshaft pulley (located on the 20th tooth counterclockwise from the missing tooth) at the 6 o'clock position.






5. Remove the 2 bolts, the 2 nuts and the RH halfshaft bracket.





6. Remove the engine plug bolt.





7. Install the Crankshaft TDC (Top Dead Center) Timing Peg.





8. NOTE: The Crankshaft TDC (Top Dead Center) Timing Peg will contact the crankshaft and prevent it from turning past TDC (Top Dead Center). However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC (Top Dead Center) position during the crankshaft pulley removal and installation.

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

Slowly rotate the crankshaft clockwise until the crankshaft contacts the Crankshaft TDC (Top Dead Center) Timing Peg.
- The TDC (Top Dead Center) marked tooth on the crankshaft pulley will align with the center line of the Crankshaft Position (CKP) sensor.






9. Disconnect the CKP (Crankshaft Position) sensor electrical connector.





10. Remove the 2 CKP (Crankshaft Position) sensor bolts and the CKP (Crankshaft Position) sensor.





Installation

1. Install the CKP (Crankshaft Position) sensor and the 2CKP (Crankshaft Position) sensor bolts.
- Do not torque at this time.






2. Connect the CKP (Crankshaft Position) sensor electrical connector.





3. Install the Crankshaft Sensor Alignment Tool.
- If the Crankshaft Sensor Alignment Tool does not align with the TDC (Top Dead Center) marked tooth on the crankshaft pulley, loosen the 2 CKP (Crankshaft Position) sensor bolts and adjust the sensor until the tool is installed.
- Tighten the 2 CKP (Crankshaft Position) sensor bolts to 7 Nm (62 lb-in).

- Remove the Crankshaft Sensor Alignment Tool.






4. Remove the Crankshaft TDC (Top Dead Center) Timing Peg.





5. Install the engine plug bolt.
- Tighten to 20 Nm (177 lb-in).






6. Install the RH halfshaft bracket, the 2 bolts and the 2 nuts.
- Tighten to 25 Nm (18 lb-ft).






7. Install the underbody shield and tighten the 4 retainers.





8. Install the RH fender splash shield.

9. After completing the repairs, use the scan tool to perform the Misfire Monitor Neutral Profile Correction procedure, following the on-screen instructions.
