🔌 Function

Reads the teeth of the sensor wheel as they pass and sends the control system a pulse for each one, which becomes the engine or shaft speed the system runs on.

⚠️ Common Signs of Failure

• Tachometer needle jumping, dropping out or reading zero
• Stored speed sensor fault and a warning lamp
• Hard starting or a stall as the signal disappears
• Engine held in a reduced power mode by the control system
• Sensor tip found chipped, oil-soaked or packed with metal debris on removal

🛠️ Service Notes

• Check the air gap to the sensor wheel and the condition of the wheel teeth before fitting a new sensor
• Inspect the connector and the harness tail for corrosion - the fault is often in the plug rather than the sensor
• Sensor 23473228 is the alternative part for a different engine set, so confirm the number against the engine
