🔌 Function
Converts the assigned operating condition into an electrical signal or processes that signal for the engine-control, display and protection system.
⚠️ Common Signs of Failure
- Incorrect, unstable or missing data
- Implausible-signal or communication fault code
- Engine warning, derate or shutdown
- Open circuit, short circuit or internal electronic failure
🛠️ 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
