The crankshaft position sensor is mounted in the transmission bellhousing at the left/rear side of the engine block (Fig. 33). On most engines, the sensor is attached with two bolts.

1. Near the rear of the intake manifold, disconnect the pigtail harness (on the sensor) from the main electrical harness.
2. Remove the nut holding sensor wire clip to fuel rail mounting stud.
3. Depending upon application, remove either the sensor mounting bolt(s) or nuts.

INSTALLATION
1. Install the sensor flush against the opening in the transmission housing.
2. Install and torque the two sensor mounting bolts (or nuts) to 19 Nm (14 ft. lbs.).

CAUTION: On some models, two bolts are used to secure the sensor to the transmission. These bolts are specially machined to correctly space the unit to the flywheel. Do not attempt to install any other bolts.
