Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to reset any electronic systems.

2. Addressing Check Engine Codes

Use the OBD-II scanner to read and document any error codes.
Clear the codes and see if the check engine light returns after a short drive.

3. Inspecting Oil Level and Quality

Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If the oil is dirty or low, change the oil and filter again with the correct specifications.

4. Inspecting the Oil Filter

If the oil filter was replaced, ensure it is properly tightened and there are no leaks.
Replace the oil filter if it is damaged or the wrong type was used.

5. Verifying Oil Pressure Sensor

Locate the oil pressure sensor and inspect for proper connection.
Use a multimeter to test the sensor's electrical output.
Replace the oil pressure sensor if it is faulty.

6. Checking Vacuum Hoses

Inspect all vacuum hoses for any that may have come loose or been damaged during the oil change.
Reconnect or replace any damaged hoses.
