Solution

1. Preparation

Gather tools and parts necessary for the repair.
Tools Required: OBD-II scanner, socket set, engine oil, oil filter wrench, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool before proceeding.

2. Address Error Codes

Use the OBD-II scanner to read and document any error codes.
Clear the codes and turn the ignition on to see if the engine light returns.

3. Check Oil Level and Filter

Remove the dipstick and wipe it clean, then reinsert and check the oil level.
If low, add oil until it reaches the proper level.
Inspect the oil filter for any signs of leakage or improper installation.

4. Tighten Components

If the oil filter or drain plug is loose, tighten them to the specified torque values (usually 20-25 ft-lbs for drain plug; follow the filter manufacturer's specifications).
Ensure that there are no visible leaks around both components.

5. Recheck Engine Sensors

Inspect wiring and connectors for any signs of disconnection or damage, especially around the oil pressure switch and any sensors that may have been disturbed during the oil change.
Reconnect any loose connectors and secure wiring.
