# 21634017 Pressure Sensor | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine electronic pressure sensor used in the engine wiring and monitoring system on Volvo Penta D9A2L marine-commercial engines. It converts the pressure at its measuring port into an electrical signal for the engine control and alarm system.

## 🚤 Compatibility

-   **Engine Family:** D, TAD, TWD
-   **HP Range:** Approximately 425-575 HP
-   **Year Range:** Approximately 2005 - 2012

## ⚙️ Key Features

-   Genuine Volvo Penta pressure sensor
-   Used in D9A2L engine monitoring
-   Electronic pressure-to-voltage signal output
-   Marine-grade sealed connector
-   Full diagnostic function within the engine-management system
-   Engine type: 9.4L inline six-cylinder turbocharged marine diesel
-   Quantity varies by assembly, most commonly one

## 🔌 Function

Measures the assigned engine-system pressure and sends a proportional signal to the control unit for display, alarm and protection functions.

## ⚠️ Common Signs of Failure

-   False low- or high-pressure alarm
-   Intermittent pressure display
-   Implausible-signal fault code
-   Engine derate or shutdown with normal mechanical pressure
-   Oil, water or corrosion inside the connector

## 🛠️ Service Notes

-   Fit into a clean, dry, undamaged port with a new sealing washer or O-ring, start it by hand, and tighten only to the figure in the workshop manual — overtightening distorts the sensing element and shifts the reading
-   Do not wrap sealing tape or smear jointing compound over the sensing face or into the port; shreds of tape travel into the system and a partly blocked port reads low
-   Handle the sensor by its body: never lever it round by the connector or the wiring, and do not knock or drop it, since a sensing element is easily damaged without any external sign
-   Mate the electrical connector clean and dry and push it fully home until it locks, then clip the harness so it cannot hang or pull on the sensor
-   Before condemning a sensor, satisfy yourself the pressure it reports is genuinely wrong — an implausible reading is often a correct report of a real fault; after fitting, check the reading is stable and sensible cold and warm and that the sensor is dry under pressure
