Installation Notes
- Ensure the engine is cool and disconnect the battery's negative terminal for safety.
- Locate the old oil pressure sensor on the engine block, typically near the oil filter.
- Place a rag or drain pan underneath the sensor to catch any residual oil.
- Carefully disconnect the electrical connector from the sensor.
- Using an appropriate wrench or socket, unscrew and remove the old sensor.
- Apply a suitable thread sealant to the threads of the new sensor, avoiding the tip.
- Install the new sensor and tighten it to the manufacturer-specified torque. Do not overtighten.
- Reconnect the electrical connector securely.
- Reconnect the battery terminal, start the engine, and check for leaks and proper gauge/alarm function.
Troubleshooting & FAQ
How do I know if my oil pressure sensor has failed?
Common signs of a failing sensor include an oil pressure warning light that stays on, flickers, or a gauge that reads either zero or maximum pressure regardless of the engine's state.
Is this sensor for a gauge or just a warning light?
This unit is an oil pressure switch, which is designed to trigger a low-pressure warning alarm or light. It is not a sender that provides a variable reading to a pressure gauge.
What is the pressure rating (PSI) for this switch?
While the exact activation PSI is not specified in the source data, these switches are calibrated to match OEM specifications for triggering a low-pressure alert under unsafe conditions for the listed engines.
Can I use this on a diesel engine?
No, this sensor is specifically designed for the Volvo Penta gasoline engine models listed in the compatibility chart. Its pressure ratings and electronic compatibility are not suited for diesel applications.
What is the difference between a sender and a switch?
A switch (like this part) is a simple on/off device that closes a circuit to trigger an alarm at a preset low pressure. A sender (or sending unit) is a variable resistor that provides a continuous signal to drive an analog or digital oil pressure gauge.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
Shipping speed & cost?
We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
