Why is my engine light on in my Ford C-Max?

Why is the engine light on in my Ford C-Max?
The engine light in your Ford C-Max illuminates when the vehicle’s onboard computer detects an issue with the engine. It is a dashboard indicator that signals the need for the engine to be diagnosed and repaired by a mechanic. The specific reasons for the engine light coming on can vary, but here are some common causes:
1. Loose or faulty gas cap: A loose or faulty gas cap can trigger the engine light to come on. Ensure that the gas cap is tightened properly after refueling.
2. Aftermarket components: Improperly installed aftermarket components, such as alarms or exhaust systems, can cause issues with the engine and trigger the engine light.
3. Engine performance issues: If the engine light stays on and the car experiences performance issues, it could indicate a major problem. The onboard computer may engage security mode, which limits available power to prevent further damage.
4. Dirty catalytic converter: A dirty catalytic converter can also trigger the engine light. If the catalytic converter becomes too dirty, it may need to be cleaned or replaced.
It is important to have the engine light diagnosed by a mechanic to determine the exact cause of the issue and to ensure that any necessary repairs are carried out.
