Crankshaft Position Sensor: Service and Repair
REMOVAL1. Disconnect negative battery cable.
2. If necessary, loosen tensioner pulleys for A/C compressor and supercharger idler pulley belts, as well as removing belts from crankshaft pulley.
3. Disconnect Crankshaft Position (CKP) sensor electrical connectors from engine wiring harness.
4. Raise vehicle and support with jackstands.
5. Remove upper and lower damper shield assemblies.
6. Rotate crankshaft by hand to position metal vane of the shutter (Attached to rear of damper) outside of sensor air gap.
7. Remove CKP sensor mounting screws and remove sensor.
INSTALLATION
1. Position CKP sensor assembly on bracket.
2. Install two sensor retaining screws but do not tighten. Install CKP sensor gauge T89P-6316-AH or equivalent to outside surface of one vane of shutter.
NOTE: Gauge is magnetic and will conform to the shape of the vane.
3. Rotate crankshaft by hand to align shutter vane with gauge into sensor air gap. Be sure to push sensor housing inward to contact gauge.
4. Tighten screws to 22-31 lb. in. (2.5-3.5 Nm).
CAUTION: This is a critical torque. Over tightening can cause damage to timing sensor.
5. Rotate crankshaft by hand to position shutter vane with gauge outside of air gap. Remove magnetic gauge.
5. Install upper and lower damper shields. Tighten fasten and lower vehicle.
NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the adaptive strategy.
