# 20706889 Sensor | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine combined pressure and temperature sensor used by compatible Volvo Penta D9 and D12 engine-management systems. It measures charge-air or boost pressure together with intake-air temperature and sends both values to the control unit.

## ⚙️ Key Features

-   Combined boost-pressure and charge-air-temperature measurement
-   Cross-referenced to Volvo numbers 20700060, 20552759, 20478260, 3985650, 20374280 and 3172522
-   Matched sensing range and connector for D9/D12 EDC systems
-   Supports fuelling, boost control, smoke limitation and engine protection
-   Correct diagnosis requires supply, ground, signal and harness checks
-   Do not substitute a pressure-only sensor with the same connector

## 🔌 Function

Measures intake/boost pressure and charge-air temperature for engine-control calculations and protection functions.

## ⚠️ Common Signs of Failure

-   Boost or intake-temperature readings are implausible or fixed
-   The engine derates or stores pressure/temperature faults
-   Power and smoke control become inconsistent
-   The signal drops out with vibration or connector movement
-   Testing shows an open circuit, short circuit or out-of-range output

## 🛠️ 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
