Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Tools Required: Oil pan, funnel, clean rag
Remove the oil fill cap and add the appropriate oil grade as specified in the owner’s manual if the oil level is low.
Clean any spills and securely replace the oil fill cap.

3. Replace Oil Filter and Oil

Tools Required: Socket set, oil filter wrench, oil catch basin
Place the oil catch basin under the oil pan.
Use the oil filter wrench to remove the old oil filter; allow oil to drain.
Lubricate the rubber O-ring on the new oil filter with fresh oil, then install the new filter.
Drain the old oil by removing the drain plug and replace it after the oil has fully drained.
Refill the engine with new oil through the oil fill cap, using the recommended type and amount.

4. Inspect and Replace Oil Pressure Sensor (if necessary)

Tools Required: Socket set, wrench set
Locate the oil pressure sensor (usually near the oil filter).
Disconnect the electrical connector and remove the sensor using the appropriate socket.
Install the new oil pressure sensor and reconnect the electrical connector.

5. Reconnect Battery and Start Engine

Reconnect the battery terminals.
Start the engine and let it idle for a few minutes.
Check for any leaks around the oil filter and oil pan.
