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 ensure safety during repairs.

2. Check and Top Off Engine Oil

Remove the oil filler cap and check oil level with the dipstick.
If low, add the recommended oil type (5W-30 synthetic or as specified in the owner's manual).
Replace the oil filler cap securely.

3. Inspect and Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter and tighten according to manufacturer specifications (usually hand-tight plus a quarter turn).

4. Test and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit.
Disconnect the electrical connector and unscrew the unit using the appropriate socket.
Install the new oil pressure sending unit, ensuring it is torqued to manufacturer specifications.
Reconnect the electrical connector.

5. Check and Replace Oil Pump (if necessary)

Drain the engine oil completely and remove the oil pan.
Remove the oil pump bolts and take out the oil pump for inspection.
Replace with a new oil pump if the old one shows signs of wear or damage.
Reinstall the oil pan with a new gasket, ensuring proper torque specifications are followed.
