Service Procedure

1. Disconnect the Intake Air Temperature (IAT) sensor electrical connector.

Loosen the throttle body hose clamp and remove the retainers from the air duct/air cleaner assembly. Move aside the air duct/air cleaner assembly as one unit.

2. Disconnect the crankshaft position sensor from the engine wiring harness. Cut the electrical connector off the crankshaft sensor assembly and remove harness from vehicle.

3. Raise the vehicle.

4. On 4WD vehicles only - Remove the front axle under body shield (steering linkage shield).





5. Remove the crankshaft position sensor retaining bolt and sensor from the engine front cover (Figure 1, Item 1).

6. Cut and discard the lower plastic harness retainer (rosebud) at the front cover bracket, remove the crankshaft position sensor assembly from the vehicle.

7. Carefully route the new crankshaft position sensor harness (Figure 1, Item 2) (connector end) up between the water pump and engine block/front cover on the right (passenger) side of the engine. The retaining clip on the harness electrical connector (Figure 1, Item 3) should be facing the front of the vehicle as it is moved up into position.

NOTICE:
DO NOT use excessive force which may damage the connector and/or harness. The use of a "Pick-Up Tool", (such as Snap On's YA837 or equivalent), to hold the connector, and a long narrow screwdriver to move and position the connector and harness will prove useful.

8. Install the crankshaft position sensor in the engine front cover. Check to see that the sensor is fully seated in the front cover prior to torquing down the retaining bolt. Torque the crankshaft sensor retaining bolt to 7-9 Nm (62-80 lbs in). USING HAND TOOLS ONLY DO NOT EXCEED TORQUE SPECIFICATION. Install the new plastic harness retainer (rosebud) to the engine front cover bracket. Check for sufficient clearance between the wiring harness and the harmonic balancer.

9. On 4WD vehicles only - Re-install the front axle under body shield, torque bolts to 32 Nm (283 lbs in).

10. Lower the vehicle.

11. Complete routing of the crankshaft position harness. The harness should be routed under the top heater hose and away from the EGR valve base.

NOTICE:
DO NOT use excessive force that may damage the connector and/or harness. Use a long pick-up tool, (such as Snap On's YA837 or equivalent), attached to the connector retaining clip loop to raise the connector and position it properly. Connect the crankshaft position sensor harness to the engine wiring harness.

12. Reinstall the air duct/air cleaner assembly. Tighten the hose clamp and install the retainers. Connect the IAT sensor harness.

13. Start and run the engine one minute to verify correct engine operation (no Malfunction Indicator Lamp illumination).

14. Install Campaign identification Label.
