🔌 Function

Measures the specified operating condition and converts it into an electrical signal for display, control, alarm or engine-protection logic.

⚠️ Common Signs of Failure

• Implausible or fixed sensor reading
• Intermittent warning, alarm or diagnostic code
• Poor starting, derate or control irregularity where the signal is used by the ECU
• Corroded pins, damaged wiring or loose connection
• Reading that differs from an independent mechanical measurement

🛠️ Service Notes

• Note how the sensor sits and how its lead is routed before removing it, and support the harness so refitting does not leave the cable strained or rubbing
• Turn the sensor with a spanner on its hex only — never lever or twist it by the connector body or the wiring, which breaks the internal joint even when the sensor looks undamaged
• Renew the O-ring or sealing washer where one is fitted, and do not add thread sealant unless the manual for your engine specifies it; sealant on the threads can break the earth path of a sensor that earths through its body
• Tighten to the figure in the workshop manual for your engine — overtightening distorts the housing and shifts or destroys the sensing element
• Make sure the connector is clean, dry and fully latched home and check the pins for corrosion and spread — a poor connector accounts for a great many faults blamed on the sensor — then run the engine and confirm the reading or warning lamp behaves sensibly before returning the boat to service
