Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to reset the system before repairs.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Read and record any stored error codes.
Clear the error codes from the system using the scanner.
Reconnect the battery.

3. Inspect the Gas Cap

Visually inspect the gas cap for cracks or damage.
Tighten the gas cap securely; if damaged, replace it with a new one.

4. Check Vacuum Lines

Inspect all vacuum lines for cracks or disconnections.
Replace any damaged vacuum hoses.

5. Battery Check

Use a multimeter to check the battery voltage; it should be between 12.4-12.7 volts when the engine is off.
Inspect battery terminals for corrosion or loose connections and clean or tighten as necessary.
