## ⚙️ Key Features

-   Genuine Volvo Penta pressure sensor
-   Electronic signal output for engine monitoring
-   Calibrated pressure range and thread specification
-   Marine/industrial sealed connector construction
-   Match the monitored circuit and engine serial number
-   Engine type: Volvo Penta electronically controlled marine or industrial diesel

## 🔌 Function

Measures the assigned system pressure and transmits a proportional signal for control, display and alarm functions.

## ⚠️ Common Signs of Failure

-   Implausible, fixed or erratic signal values
-   Starting, speed-control or protection-system fault codes
-   Intermittent signal loss caused by heat or vibration
-   Oil, coolant or water contamination in the connector
-   Open-circuit, short-circuit or incorrect air-gap test results

## 🛠️ 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
