Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and park the vehicle on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Check Oil Level and Condition

Remove the dipstick and clean it with a rag.
Reinsert the dipstick, then remove it again to check the oil level.
If the oil level is low, add the appropriate type of oil as specified in the owner’s manual.

3. Replace Oil Filter

Tools Required: Oil filter wrench, oil catch pan
Remove the old oil filter using the oil filter wrench.
Apply a thin layer of oil to the rubber seal of the new filter.
Install the new oil filter by hand until snug, then tighten slightly more with the wrench.

4. Replace Oil Pressure Sending Unit

Tools Required: Socket set, torque wrench
Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector.
Using a socket, remove the old sending unit.
Install the new sending unit and tighten to the manufacturer's specifications (refer to service manual for torque values).
Reconnect the electrical connector.

5. Check for Oil Leaks

After completing the repairs, start the engine and let it idle.
Inspect the area around the oil filter and sending unit for any leaks.
If no leaks are present, proceed to the next step.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and monitor the oil pressure warning light.
Perform a test drive to ensure the light remains off and the engine operates smoothly.
