Serial Number Fitment Notice
Oil pressure sensor fitment depends on the exact Volvo Penta engine model, instrument system, sensor range, wiring setup, and serial number. Always confirm compatibility using the engine serial number and the Volvo Penta parts diagram before ordering, especially when replacing earlier reference 843231 with 866833.
When This Part Needs Replacement
Replace this sensor if the oil pressure reading is inaccurate, intermittent, missing, or inconsistent after confirming actual mechanical oil pressure. It should also be replaced if the sensor body, connector, terminals, or wiring interface is damaged, corroded, leaking, or no longer providing a reliable signal.
Installation Notes
Confirm that the replacement sensor matches the original pressure range and electrical system before installation. Inspect the connector, wiring, oil port, and surrounding harness while servicing the sensor. Use the correct thread sealing method only if specified for the application, and verify oil pressure readings after installation against the engine's expected operating range.

Parts Desk Insight
The key detail with this sensor is the 0–10 bar oil pressure range. Similar-looking Volvo Penta pressure sensors may use different ranges or apply to different monitoring positions, so matching by part number, engine serial number, and diagram location is the safest way to avoid an incorrect reading.
