22320906 Pressure Sensor | Genuine Volvo Penta Part

🔧 Product Description

A genuine pressure sensor that measures charge-air or inlet-manifold pressure and sends the value to the engine control system. The ECU uses this signal for boost control, fuel delivery, smoke limitation, diagnostics and engine protection. The sensor is used across D3, D4, D6 and selected D11 marine platforms and replaces earlier Volvo Penta sensor references.

⚙️ Key Features

• Genuine Volvo Penta electronic pressure sensor
• Measures boost or inlet-manifold absolute pressure
• Current OEM replacement for 21385453
• Supports fuel, turbocharger and emissions control calculations
• Requires a clean pressure port and undamaged sealed electrical connector

🔌 Function

Converts intake or boost pressure into an electrical signal used by the ECU to calculate engine load, turbocharger performance and safe fuel quantity.

⚠️ Common Signs of Failure

• Loss of power or poor acceleration
• Underboost or implausible pressure fault codes
• Unstable idle or incorrect fuelling response
• Engine derate or protective mode
• Corroded pins, damaged wiring or oil contamination in the connector
• Incorrect readings caused by a blocked pressure port

🛠️ 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
