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
