Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical shorts.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Oil filter wrench
Multimeter (if needed for sensor testing)

2. Check Engine Codes

Reconnect the battery.
Use the OBD-II scanner to check for error codes.
Note any codes present for further investigation.

3. Inspect Oil Filter and Oil Level

Remove the oil filter using an oil filter wrench.
Inspect the rubber O-ring for damage or residues that may cause leaks.
Install a new filter if necessary.
Check the oil level using the dipstick; add oil if low, ensuring the correct type is used.

4. Tighten Oil Drain Plug

Inspect the oil drain plug to ensure it is not loose.
Use a torque wrench to tighten the drain plug to the manufacturer’s specifications (usually around 25-30 ft-lbs, verify with the service manual).

5. Inspect Engine Sensors

Visually inspect the wiring and connectors of the oil pressure switch and any related sensors.
Use a multimeter to test the oil pressure switch for proper functionality.

6. Clear Error Codes

After addressing the issues, use the OBD-II scanner to clear the error codes.
Reconnect the battery if it was disconnected.
