## ⚙️ Key Features

-   Application-specific sensing range and electrical output
-   Matched connector and mounting interface for the documented monitoring circuit
-   Provides live data to the engine-control, alarm or display system
-   Designed for engine vibration, heat and fluid exposure at the assigned location
-   Correct diagnosis requires signal, supply, ground and harness checks
-   Serial-number confirmation prevents mixing sensors with different calibration ranges
-   Engine type: Volvo Penta D7 inline-six industrial diesel

## 🔌 Function

Converts a measured engine condition into an electrical signal.

## ⚠️ Common Signs of Failure

-   The displayed reading is implausible, fixed or intermittent
-   A false warning, alarm or control-system fault is recorded
-   Connector corrosion or wiring damage affects the signal
-   Engine performance changes because incorrect data reaches the control system
-   Testing shows an open circuit, short circuit or signal outside specification

## 🛠️ 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
