# 22031626 Pressure Sensor | Genuine Volvo Penta Part

## 🔧 Product Description

Electronic pressure sensor mounted on the common rail of Volvo Penta TAD540-TAD542VE engines. It measures rail pressure for the engine control module and is critical to injection quantity, timing and system protection. listed fitment: TAD540-42VE, TAD550-51VE, TAD552VE.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD552VE
-   Volvo Penta TAD550-51VE
-   Volvo Penta TAD540-42VE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Common-rail pressure measurement
-   TAD540-TAD542VE fuel-system application
-   Factory electrical connector and calibration
-   Installed on common rail 21860425
-   Supports closed-loop injection-pressure control
-   Engine type: 4-cylinder turbocharged common-rail industrial diesel

## 🔌 Function

Converts fuel-rail pressure into an electrical signal used by the ECM to regulate the high-pressure pump and injector operation.

## ⚠️ Common Signs of Failure

-   Hard starting or no-start
-   Engine derate or shutdown
-   Unstable idle or surging
-   Rail-pressure circuit, plausibility or regulation fault codes
-   Incorrect live-data pressure compared with commanded pressure

## 🛠️ 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
