What This Sensor Does
The 22422785 is a genuine Volvo Penta OEM MAP (manifold absolute pressure) and boost pressure sensor. It feeds real-time intake pressure data to the engine control unit, allowing the ECU to optimize fuel delivery, manage turbo boost, and protect the engine under load. Accurate boost pressure data is critical for performance, fuel economy, and emissions compliance on these diesel platforms.

Volvo Penta used similar pressure-sensor housings and connectors across multiple engine families. Always confirm fitment using your engine serial number and the correct Volvo Penta parts diagram.
Serial Number Requirement
Boost and MAP sensors can share identical housings while serving different control functions depending on emissions calibration and harness version. Match part number 22422785 to your specific engine serial number and the correct Volvo Penta electrical schematic before ordering. Appearance alone is not a reliable guide.
When to Replace This Sensor
- Active fault codes pointing to boost pressure or MAP sensor circuit faults
- Engine derate or reduced power mode with no other obvious cause
- Inaccurate boost readings or erratic turbo behavior
- Damaged connector, cracked housing, or contamination during service
- Routine replacement as part of a scheduled sensor service interval
Installation Notes
- Confirm the exact schematic position (object key 53) before removal
- Verify the 4-pin connector matches the removed sensor before installation
- Inspect the sealing surface and mounting boss for damage or debris
- Clear fault codes and verify sensor readings after installation
Superseded Part Numbers
22422785 is the current active Volvo Penta OEM number, replacing earlier part number 22329559. Cross-reference sources also associate 21097978 in boost-pressure sensor interchange listings — treat this as a related reference, not a confirmed Volvo Penta service supersession.
Parts Desk Insights
The most common mistake with this sensor is matching by connector shape alone. Volvo Penta used very similar 4-pin pressure sensor formats across D8, D11, and multiple TAD families — sometimes with different calibrations for different emissions tiers. Pulling the serial-number-based diagram first almost always saves a return. If a customer is chasing an intermittent derate or a fault code that clears and returns, this sensor is a frequent culprit worth checking early in the diagnostic process.
