Solution

1. Preparation

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

2. Check Oil Level

Remove the dipstick, wipe it clean, reinsert, and remove again to check the oil level.
If low, add the appropriate type and amount of engine oil as specified in the owner’s manual.

3. Inspect for Leaks

Visually inspect the oil filter, oil pan, and drain plug for signs of leaks.
If any leaks are found, replace the faulty components (e.g., oil filter or seals).

4. Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit, typically found near the oil filter.
Use a socket to remove the sending unit.
Install the new sending unit, torquing it to the manufacturer’s specifications.
Reconnect the electrical connector.

5. Change Engine Oil and Filter

Drain the old oil using a socket to remove the drain plug; allow it to fully drain into a pan.
Replace the oil filter using an oil filter wrench; ensure the old filter's rubber O-ring is removed.
Reinstall the drain plug and torque it to manufacturer specifications.
Fill the engine with new oil as per the manufacturer’s recommendations.

6. Reconnect Battery and Start Engine

Reconnect the battery and start the engine to check for leaks around the oil filter and drain plug.
Monitor the oil pressure light for any warnings and ensure the engine runs smoothly.
