Installation Notes
- Disconnect the negative battery terminal before beginning work.
- Locate the existing oil pressure sensor on the engine block. Clean the surrounding area to prevent contamination.
- Place a suitable container or absorbent rags below the sensor to catch any dripping oil.
- Carefully disconnect the electrical wire from the old sensor.
- Using the correct size wrench, unscrew and remove the old sensor.
- Compare the old sensor with the new one to ensure the threads and fitting are identical.
- Apply a small amount of appropriate thread sealant to the new sensor's threads, avoiding the sensor's orifice.
- Thread the new sensor into the engine block by hand to prevent cross-threading.
- Tighten the sensor to the manufacturer's specified torque. Do not overtighten.
- Reconnect the electrical wire securely.
- Reconnect the battery terminal, start the engine, and check for any leaks around the new sensor.
Troubleshooting & FAQ
How do I know if my oil pressure sensor is failing?
Common signs include an oil pressure warning light on the dash, a gauge reading of zero or max, or erratic gauge behavior. Verifying with a mechanical gauge is recommended before replacing the sensor.
Is this part a switch or a sender?
This component functions as an oil pressure sensor/switch. It's designed to trigger a warning light or alarm when oil pressure drops below a specific threshold, rather than providing a variable reading to a gauge.
What if a new sensor doesn't fix my oil warning light?
If a new sensor doesn't resolve the issue, inspect the wiring and electrical connector for faults, corrosion, or a loose connection. The problem may also be low oil pressure in the engine itself, which requires immediate mechanical inspection.
