my Ford Mustang S650 (2024-Present) engine light is on, what are common reasons?

Solution

1. Preparation

• Gather tools including OBD-II scanner, socket set, and safety goggles.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure the vehicle is parked on a flat surface and secured with wheel chocks.

2. Address Error Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Retrieve and document any trouble codes.
• Research specific codes to determine potential causes (e.g., P0420 for catalytic converter efficiency).

3. Perform Necessary Repairs

• If the gas cap is faulty, replace it with a new OEM cap.
• For air filter issues, remove the air intake assembly, replace the filter, and clean any debris from the intake.
• If engine oil is low, top it up with the manufacturer-recommended oil type.
• For an exhaust leak, visually inspect and replace any damaged pipes or gaskets.

4. Clear Error Codes

• After repairs, use the OBD-II scanner to clear the error codes.
• Reconnect the negative battery terminal.

5. Test Drive

• Start the engine and allow it to reach operating temperature.
• Monitor engine performance during a test drive, checking for any new warning lights or issues.
