Oil pressure sensor - Volvo Penta 21202753 is a monitoring sensor: it turns pressure, temperature or speed into an electrical signal the controller uses to protect the engine.
A miscalibrated sensor is more dangerous than a dead one: the dead one trips an alarm, the lying one lets the engine run out of range unnoticed. If the reading jumps or disagrees with reality, replace it.

How to verify before ordering
- Match measuring range and output curve (resistance, 4–20 mA or 0–5 V) to what the controller expects.
- Check thread type and length; a sensor that does not seat leaks and reads wrong.
- Confirm maximum admissible pressure or temperature against the actual mounting point.
- The reference shown on this listing is 21202753; cross-check it against the one stamped on the removed part.
Frequently asked questions
Can I bridge the sensor to keep running?
Only as a diagnostic test, never in permanent service. Bridging removes the protection and a real fault goes unnoticed.
Why does the alarm only appear when hot?
The fault is in the sensor insulation or in the connector, which expands with temperature. Cold resistance is correct so no alarm shows.
