Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Prepare a clean workspace.

2. Scan and Analyze Codes

Use the OBD-II scanner to read any stored error codes.
- Document the codes for reference.
- Clear the codes and perform a test drive to see if they reappear.

3. Inspect and Repair Faulty Components

A. Air Intake System

Inspect the air filter for dirt or blockages.
Check the intake hoses for cracks or leaks.
If damaged, replace the air filter and any defective hoses.

B. Fuel System

Connect a fuel pressure gauge to the fuel rail to check pressure.
If pressure is low, inspect the fuel pump and filter.
Replace any faulty components.

C. Ignition System

Remove spark plugs and inspect for wear or fouling.
Test ignition coils for proper operation using a multimeter.
Replace damaged spark plugs or coils.

D. Exhaust System

Inspect the catalytic converter for clogs or damage.
If issues are found, replace the catalytic converter.

4. Reassemble and Test

Reconnect all components and ensure all connections are secure.
Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes.
Perform a test drive to ensure that the check engine light does not return.
