Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to reset the system.

2. Address Faulty Components

A. Replace Faulty Spark Plugs

Remove the ignition coils using a socket set.
Unscrew and remove spark plugs using a spark plug socket.
Inspect the old spark plugs for wear; replace with new ones if needed.
Torque the new spark plugs to the manufacturer’s specifications (typically around 15-20 ft-lbs).

B. Replace the MAF Sensor (if faulty)

Disconnect the MAF sensor electrical connector.
Remove the screws holding the MAF sensor in place.
Install the new MAF sensor and secure it with screws.
Reconnect the electrical connector.

3. Reassemble and Reset

Reconnect the negative battery terminal securely.
Clear any stored fault codes using the OBD-II scanner.

4. Test Drive

Start the engine and allow it to reach operating temperature.
Monitor the engine performance and check that the check engine light does not reappear.
