# 21636166 Pressure Sensor | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine three-pin pressure sensor used in Volvo-derived auxiliary or climate-control systems fitted to selected Volvo Penta industrial installations. It converts system pressure into an electrical signal for control, protection and diagnostic functions.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta HPCU-A
-   Volvo Penta TB66-A
-   Volvo Penta TB66-150-A
-   Volvo Penta HPCU-B

-   **Engine Family:** HPCU, TB
-   **Year Range:** Approximately 2012 - current production-era applications

## ⚙️ Key Features

-   Genuine Volvo pressure sensor
-   Three-pin electronic connection
-   Used in pressure monitoring and switching applications
-   Sealed electrical construction
-   Several documented independent-brand equivalents
-   Engine type: Volvo Penta industrial engine auxiliary pressure-monitoring system

## 🔌 Function

Measures the assigned system pressure and supplies an electrical value used to operate, protect or diagnose the connected auxiliary system.

## ⚠️ Common Signs of Failure

-   Incorrect or intermittent pressure reading
-   Auxiliary system failing to engage
-   Open- or short-circuit fault code
-   Connector corrosion or moisture entry
-   System operation at incorrect 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
