Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during the repair.

2. Check and Add Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If oil is low, add the recommended oil type (e.g., 5W-30 or as specified in the owner’s manual) through the oil filler cap.
Recheck the oil level and ensure it is within the acceptable range.

3. Replace Oil Filter

Locate the oil filter; refer to the owner's manual for the exact location.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten it according to the manufacturer’s specifications (usually about 3/4 turn after the gasket makes contact).

4. Inspect and Replace the Oil Pressure Sensor

Locate the oil pressure sensor, typically near the oil filter or on the engine block.
Disconnect the electrical connector from the sensor.
Use a socket to remove the oil pressure sensor.
Install the new oil pressure sensor and reconnect the electrical connector.

5. Test Oil Pressure

Install a mechanical oil pressure gauge into the oil pressure sensor port.
Start the engine and let it idle, then observe the pressure readings.
Compare the readings with the specifications provided in the owner’s manual.

6. Reassemble and Recheck

Reconnect the battery.
Start the engine and let it run for a few minutes.
Check for any leaks around the oil filter and oil pressure sensor.
Monitor the oil pressure warning light to confirm whether it remains off.
