Volvo Penta 22422785 is a genuine OEM sensor used in select Volvo Penta heavy-duty marine and industrial engine applications. Current Volvo Penta parts references place this part in D8A1-A MP / Cables and Fuses schematics, while broader sensor catalogs and cross-reference sources identify it as a boost pressure / MAP-style sensor, often described as an intake air temperature and boost pressure sensor assembly. Current Volvo Penta dealer sources also show 22422785 as the active replacement for earlier part number 22329559.
Key Features
- Genuine Volvo Penta OEM part number 22422785.
- Identified in current Volvo Penta schematic references as Sensor, schematic object key 53.
- Strongest schematic application reference places it in D8A1-A MP / Cables and Fuses.
- Current cross-reference sources describe it as a MAP / boost pressure sensor, with one technical catalog listing it as a 4-pin, 5V sensor with a 0–72.52 psi measurement range.
- Dealer weight references are around 0.05 lb.
Engine Compatibility
The strongest supportable fitment for 22422785 is within Volvo Penta D8 and D11 marine propulsion and industrial applications, with current sources listing D8A1-A MP, D8A2-A, D8A3-A, D8A4-A, D8A5-A, D8A6-A, D11B1-A MP, D11B2-A MP, D11B3-A MP, and D11B4-A MP. Broader cross-reference sources also associate it with many TAD engine families, including TAD1140VE, TAD1141VE, TAD1142VE, TAD1150VE, TAD1151VE, TAD1152VE, TAD1170VE, TAD1171VE, TAD1172VE, TAD1180-83VE, TAD1341-1343GE-B, TAD1351VE, TAD1371VE, TAD1650VE-B, TAD1670VE, TAD540VE, TAD550VE, TAD570VE, TAD840VE, TAD850-52VE, TAD870VE, and TAD880-84VE. Because sensor usage can vary by emissions family, harness version, and engine control configuration, final fitment should still be confirmed by serial number and the correct Volvo Penta parts diagram.
Serial Number Fitment Notice
Match Volvo Penta part number 22422785 to your engine serial number and the correct Volvo Penta electrical or sensor diagram before ordering. Sensors can share similar housings and connectors while serving different control functions, so exact schematic match matters more than appearance alone.
When This Part Needs Replacement
This sensor should be replaced when boost-pressure or intake-pressure readings become inaccurate, fault codes or derate symptoms point to a failed sensor, or when the connector, housing, or sensing element is damaged or contaminated during service. This service guidance is a practical inference from the part being identified across current sources as a boost-pressure / MAP-style sensor in engine electrical systems.
Installation Notes
Confirm the exact application in the correct Volvo Penta schematic before installation, and compare the removed sensor carefully against the replacement part. Inspect the connector, sealing area, and mounting location before reassembly. One current technical catalog identifies this sensor as a 4-pin Bosch-style plug sensor, which is a useful checkpoint when matching the old part to the new one.
Alternate/Superseded Part Numbers
Current Volvo Penta dealer sources show 22422785 as the active OEM number replacing 22329559. Broader cross-reference sources also associate it with 21097978 in boost-pressure sensor interchange listings, but that is best treated as a related reference number rather than a confirmed Volvo Penta service supersession.
Parts Desk Insight
With sensors like this, the easy mistake is matching only by connector shape. Checking the exact serial-number-based diagram first usually saves time, especially when Volvo Penta used similar pressure-sensor formats across D8, D11, and multiple TAD engine families.
