22052384 Pressure Sensor | Genuine Volvo Penta Part

🔧 Product Description

Electronic pressure sensor used by the Volvo Penta monitoring system to measure coolant or seawater-circuit pressure on large marine engines. It supplies the ECU/EVC with a calibrated signal for protection, alarms and diagnostics.

🚤 Compatibility

• Engine Family: D

Full model list at the end of this description.

⚙️ Key Features

• Calibrated pressure-sensing element
• Sealed engine-room electrical connector
• Provides live data to ECU/EVC protection logic
• Exact pressure range and signal curve must match
• Product, serial and software calibration controlled
• Quantity varies by assembly, most commonly one

🔌 Function

Converts system pressure into an electrical signal used for display, alarm, protection and diagnostics.

⚠️ Common Signs of Failure

• Missing, implausible or unstable pressure reading
• False low-pressure alarm or engine derate
• Open/short-circuit diagnostic code
• Fluid leakage through the sensor body
• Corroded connector pins or damaged wiring

🛠️ 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
