CRANKSHAFT POSITION SENSOR - 2.5L

REMOVAL

1. Remove speed control servo from driver's side strut tower.
2. Remove crankshaft position sensor retaining bolt Crankshaft Position Sensor
3. Pull crankshaft position sensor straight up out of the transaxle housing.
4. (Disconnect crankshaft position sensor electrical connector from the wiring harness connector.

INSTALLATION - ADJUSTABLE All vehicles will be equipped with an adjustable crankshaft position sensor. This can be identified by an elongated mounting hole in the sensor.
NOTE: If the removed sensor is to be reinstalled, clean off the old spacer on the sensor face. A NEW SPACER must be attached to the sensor face before installation. If the sensor is being replaced, confirm that the paper spacer is attached to the face of the new sensor Crankshaft Position Sensor and Spacer

1. Install sensor in transaxle and push sensor down until contact is made with the drive plate. While holding the sensor in this position, install and tighten the retaining bolt to 12 N·m (105 in. lbs.) torque.
2. Connect crankshaft position sensor electrical connector to the wiring harness connector.
3. Attach connector to heater tube bracket.
4. Install speed control servo. Tighten nuts to 9 N·m (80 in. lbs.) torque.

crankshaft position sensor location for 3.3 V6 engine is mounted at the rear of the engine on transmission bellhousing, the 3.5 V6 engine crankshaft sensor located at front of the engine on the aluminum oil pan section below crankshaft pulley.replace the crankshaft position sensor remove heat shield disconnect the electrical connector the remove sensor retaining bolt then remove crankshaft sensor.after replacing crankshaft sensor you need to erase code if check light come back on.

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Remove the serpentine drive belt from the crankshaft pulley.
3. Raise and safely support the vehicle.
4. Remove the right front wheel and tire assembly and the right inner fender access cover/splash shield.
5. Using a 28mm socket, remove the crankshaft harmonic balancer retaining bolt.
6. Remove the crankshaft balancer, using a puller if necessary.
7. For 1992-99 vehicles, remove the CKP sensor shield. Fig. 1: If so equipped, remove the crankshaft position sensor shield
   
   
8. Unplug the sensor electrical connector.
9. For 1987-91 vehicles, perform the following:
   1. Remove the sensor and pedestal from the block face.
   2. Remove the sensor from the pedestal.
10. For 1992-99 vehicles, remove the sensor from the block face. To install:
    1. For 1987-91 vehicles, perform the following:
    2. Loosely install the crankshaft sensor on the pedestal.
    3. Position the sensor, with the pedestal attached, on crankshaft sensor installation tool J 37089 or equivalent.
    4. Install the bolt to hold the pedestal to the block face, then tighten to 14-28 ft. lbs. (20-40 Nm). Fig. 2: Position the crankshaft sensor tool on the crankshaft
       Fig. 3: Insert the crankshaft sensor tool into the harmonic balancer
       
       
    5. Tighten the pedestal pinch bolt to 30-35 inch lbs. (3-4 Nm).
    6. Remove the special tool.
    7. Place the crankshaft sensor tool on the crankshaft balancer and turn. If any vane on the harmonic balancer touches the tool, replace the balancer.
11. For 1992-99 vehicles, install the CKP sensor on the block.
    1. Install the retaining bolts and tighten to 14-28 ft. lbs. (20-40 Nm).
    2. Install the crankshaft position sensor shield.
    3. Attach the sensor electrical connector.
12. Install the balancer on the crankshaft.
13. Tighten the crankshaft bolt to 200-239 ft. lbs. (270-325 Nm) for 1987-91 vehicles. For 1992-99 vehicles, tighten to 110 ft. lbs. (150 Nm), plus an additional 76°rotation.
14. Install the inner fender shield and the right tire and wheel assembly.
15. Carefully lower the vehicle.
16. Install the serpentine belt.
17. Connect the negative battery cable.

The crank sensor is located on the engine near the flywheel axis of the crankshaft.

Crankshaft Position Sensor Removal & Installation To Remove:
Location of the crankshaft position sensor on the 2.4L engine
Location of the crankshaft position sensor on the 3.0L engine
Location of the crankshaft position sensor on the 3.3L and 3.8L engines
NOTE: On the 2.4L engine, the crankshaft position sensor is mounted to the engine block behind the alternator, just above the oil filter. On the 3.0L, 3.3L and 3.8L engines, the crankshaft position sensor is mounted on the transaxle housing, above the vehicle speed sensor.

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Disconnect the crankshaft position sensor electrical connector.
4. Unfasten the sensor mounting screw, then remove the sensor from the vehicle by pulling it straight out.

To Install:
NOTE: If the sensor removed is going to be re-installed, clean off the old spacer on the sensor face. A new spacer must be attached to the sensor face before installation. If the sensor is being replaced, be sure that a paper spacer is attached to the sensor face.

1. Install sensor and push the sensor in until contact is made. While holding the sensor in this position, install and tighten the mounting bolt to 105 in. lbs. (12 Nm).
2. Connect the crankshaft position sensor electrical connector.
3. Lower the vehicle.
4. Connect the negative battery cable.

Hi!!

here are illustrations of the CKP (crankshaft position) sensor in 2.3L and 3.0L.

Note: In the bottom of the 2.3L drawing says Trottle Position (TP) Sensor, this is wrong, It should say CKP Sensor.


2.3L Engine


The Crankshaft Position (CKP) sensor is located to the left of the crankshaft pulley.

Fig. Crankshaft Position (CKP) sensor location-2.3L engine


3.0L Engine


The Crankshaft Position (CKP) sensor is located just behind the crankshaft pulley on engine block.

Fig. Crankshaft Position (CKP) sensor location-3.0L engine

The cost of the sensor is $23 bucks at AutoZone.
