Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick fully and remove it again to check the oil level.
If the level is low, add the correct oil type as specified in the owner's manual.

3. Inspect Oil Filter

Locate the oil filter and check for proper installation.
If the filter is loose, use an oil filter wrench to tighten it to the manufacturer’s torque specifications.
If damaged, replace it with a new filter.

4. Test Oil Pressure Sensor

Locate the oil pressure sensor, usually near the oil filter or engine block.
Disconnect the electrical connector and use a multimeter to check for continuity.
If faulty, replace the sensor with a new one.

5. Clear Error Codes

Reconnect the battery.
Use the OBD-II scanner to clear any error codes related to oil pressure.
Start the engine to see if the oil light remains illuminated.
