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 while working.

2. Check and Top Off Oil Level

Tools Required: Oil funnel, clean rag, appropriate engine oil
Remove the oil dipstick, wipe it clean, and reinsert it fully.
Pull out the dipstick again to check the oil level.
If low, add the manufacturer-recommended oil type through the oil filler cap using a funnel until the correct level is reached.

Visually inspect the engine oil pan, oil filter, and seals for any signs of leaks.
Clean any areas with oil residue and monitor for new leaks after the vehicle runs.

4. Replace Oil Filter and Change Oil (if necessary)

Tools Required: Socket set, oil filter wrench, oil catch pan
Drain the old oil using an oil catch pan; remove the oil drain plug.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug once oil has drained completely.
Fill the engine with new oil via the oil filler cap.

5. Check and Replace Oil Pressure Sending Unit

Tools Required: Socket set, wrench set
Locate the oil pressure sending unit on the engine (refer to the service manual for specific location).
Disconnect the electrical connector and remove the unit.
Install the new oil pressure sending unit and reconnect the electrical connector.

6. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the engine and monitor for any warning lights on the dashboard.
Take the vehicle for a short test drive to ensure proper oil pressure and function.
