contacting belt or pulleys.
1. Disconnect the speed sensor pigtail harness from the main engine wiring harness near the front/top of engine.
2. Remove the clip bolts from the sensor pigtail wiring harness.

INSTALLATION/ADJUSTMENT
Engine Speed Sensor
1. The engine speed sensor uses a slotted hole on one side to adjust its depth. A brass (non-magnetic) feeler gauge must be used to adjust the sensor.
Sensor-to-vibration damper air gap is 1.25 mm (.049 in.) minimum to 1.30 mm (.051 in.) maximum.
2. Position speed sensor, its mounting spacers and two mounting nuts to the engine. Install mounting nuts finger tight.
3. Route sensor wiring harness behind engine pulleys. Install and tighten wiring harness clip bolts.
4. Place the feeler gauge between the sensor and the vibration dampener.
