Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and take note of any error codes displayed on the scanner.
Clear the codes to reset the check engine light and see if it reappears after a test drive.

3. Inspect and Replace Components

A. Spark Plugs

Remove the ignition coil or spark plug wire.
Use a spark plug socket to remove the spark plugs.
Inspect the condition; replace if worn or fouled.
Torque new spark plugs to the manufacturer's specification (usually between 15-30 Nm).

B. Air Filter

Open the air filter housing by releasing the clips or screws.
Remove the old air filter and inspect for dirt and debris.
Install a new air filter, ensuring it fits snugly in the housing.
Close the housing securely.

C. Vacuum Hoses

Visually inspect all vacuum hoses connected to the intake manifold.
Replace any cracked or damaged hoses.
Ensure all connections are tight and secure.

4. Reassemble and Test

Reconnect the battery.
Start the engine and check for any unusual sounds or behaviors.
Take the vehicle for a test drive to ensure the engine light does not reappear.
