🔌 Function

Senses the passing teeth of the sensor wheel and converts them into the pulse train the control system reads as speed, so fuelling and protection strategies have something to work from.

⚠️ Common Signs of Failure

• Speed reading unstable or missing at the helm
• Fault code logged against the engine speed signal
• Engine cutting out or refusing to start hot
• Power reduced by the control system as a protective measure
• Sensor face found scored, corroded or coated in magnetic debris

🛠️ Service Notes

• Set and check the air gap to the sensor wheel - too large a gap gives exactly the same symptoms as a dead sensor
• Clean the sealing face and fit a new O-ring or seal if the sensor is a wet-mounted one
• Sensor 23473109 covers the larger fitment list, so order by number rather than by appearance
