Remove the sensor. Inspect the condition of the end of the magnet. Look for signs of wear and contaminants.
Clean any debris from the face of the magnet.
The sliphead must be fully extended when the speed/timing sensor is installed so that the sensor maintains the correct clearance with the speed-timing wheel. If the correct clearance is not maintained, the signal from the sensor will not be generated.Do not install the sensor between the teeth of the speed-timing wheel. Damage to the sensor would result. Before installing the sensor, ensure that a tooth of the wheel is visible in the mounting hole for the sensor.
Install the engine speed sensor.
Coat the threads of the sensor with 4C-5597 Anti-Seize Compound.
Install the sensor. For the proper torque, refer to the engine's Specifications manual.
