why does my Ford Mustang S650 (2024-Present) engine light keep coming back on

Solution

1. Preparation

• Gather tools and parts needed for repairs.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before proceeding.

2. Addressing Error Codes

• Use the OBD-II scanner to retrieve and note down error codes.
• Research each code to determine potential causes and fixes.
• For common codes like P0420 (catalytic converter efficiency), consider inspecting the converter.

3. Inspecting and Replacing Components

A. Gas Cap

• Remove the gas cap and inspect for cracks or worn seals.
• Replace with a new gas cap if damaged.

B. Air Filter

• Locate the air filter housing and remove it.
• Inspect the air filter; replace if dirty or clogged.

C. Oil Check

• Remove the oil dipstick; check oil level and quality.
• Change the oil and filter if the oil appears dark or contaminated.

4. Exhaust System Inspection

• Visually inspect the exhaust system for any signs of rust, holes, or leaks.
• Repair or replace any damaged components as necessary.
