Solution

1. Preparation

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

2. Retrieve and Address Diagnostic Codes

Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs).
Document any codes that appear and refer to a repair manual for their meanings.
If codes are related to oil pressure or oil quality, continue with further diagnosis.

3. Inspect and Replace Oil Filter (if necessary)

Remove the oil filter using an oil filter wrench.
Inspect the old filter for debris or damage.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, tightening it to the manufacturer's specifications (usually hand-tight plus a quarter turn).

4. Address Any Leaks

Inspect the area around the oil filter and oil pan for oil leaks.
Tighten any loose bolts or connections.
If leaks are found, replace any gaskets or seals that may be compromised.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear existing error codes from the ECU.
Start the engine and allow it to idle, monitoring for any new codes or warning lights.
