Note: The engine speed sensor is commonly referred as a magnetic pickup sensor.

This adjustment procedure is for the engine speed sensor.

1. Remove the speed sensor (1) from the flywheel housing. Remove all debris from the tip of the speed sensor. Align a ring gear tooth directly in the center of the threaded sensor opening.

2. By hand, screw the speed sensor (1) into the hole until the end of the sensor contacts the gear tooth.

3. Turn the sensor (1) in the counterclockwise direction through 270 degrees (three-fourths turn).

4. Tighten locknut (2) to 25 ± 5 N·m (18 ± 4 lb ft).

   Note: Do not allow speed sensor (1) to turn as locknut (2) is tightened.
