Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, oil filter wrench, multimeter.
Ensure the vehicle is on a level surface and the engine is cool before starting repairs.

2. Check and Reset Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any error codes present and note them for further action.
If the codes are related to the oil change (such as oil pressure or O2 sensor), proceed to the next steps.
Clear the error codes from the system.
Start the engine and check if the check engine light re-illuminates.

3. Verify Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If oil is low, top it off with the appropriate oil type as specified in the owner’s manual.
If the oil appears dirty or contaminated, consider performing an additional oil change with a new filter.

4. Inspect Oil Filter Installation

Use an oil filter wrench to remove the oil filter.
Inspect the old filter for any rubber O-ring that may have remained on the engine, which can cause leaks.
Install a new oil filter, ensuring it is tightened according to manufacturer specifications (usually hand-tight plus 3/4 turn).

5. Check for Loose Connections

Inspect all electrical connections and hoses around the engine for any that may have been inadvertently disconnected during the oil change.
Reconnect any loose or disconnected components securely.
