Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, torque wrench, multimeter, replacement parts as needed.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle's OBD-II port.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner's instructions to read and record any DTCs.

3. Addressing Common Issues

Gas Cap: If a code indicates an evaporative emission system leak, check and replace the gas cap if it's cracked or unable to seal.
Air Filter: If the air filter is dirty, remove the air intake cover, detach the filter, and replace it with a new one. Ensure it is seated properly.
Exhaust Leaks: Inspect the exhaust pipe and manifold for cracks or holes. Replace any damaged sections and tighten any loose connections.

4. Clear Fault Codes

After repairs, use the OBD-II scanner to clear the fault codes.
Turn off the scanner and disconnect it from the port.

5. Final Inspection

Start the engine and allow it to idle for a few minutes.
Listen for unusual sounds and monitor the engine's performance.
