The check engine light is perhaps one of the most dreaded warning symbols that can illuminate on the dashboard of Ford EcoSport. In this article, we will delve into the most common causes behind the check engine light.

The check engine light illuminates in Ford EcoSport when the on-board diagnostic system detects a problem with the engine or emissions system. If left unchecked, the issue could cause more serious problems and result in costly repairs.

Static CEL: A static check engine light in EcoSport means that there is a problem with the engine or emissions system, but it is not an urgent issue. The vehicle can typically be driven safely for a short period of time, but it should be taken to a mechanic soon to avoid further damage or increased emissions.

Flashing CEL: When the check engine light is flashing in EcoSport, it indicates that there is a significant problem with the engine that requires immediate attention. The flashing light often indicates a misfire, which can cause damage to the catalytic converter. When this happens, the engine should be turned off immediately to prevent further damage.

1. Loose or bad gas cap

It is possible for the check engine light to come on in EcoSport due to a loose or bad gas cap. The fuel system in modern vehicles is designed to maintain a certain level of pressure, and if the gas cap is not sealing properly, it can cause a leak and disrupt the pressure balance in the system. This can trigger the vehicle’s onboard diagnostic system, which may illuminate the check engine light.

Tighten the gas cap

If you suspect that your gas cap may be the cause of the problem, you can try tightening it to see if the light goes off. If the cap is damaged or worn out, it may need to be replaced. In either case, once the issue has been resolved, you may need to drive your EcoSport for a few miles to allow the onboard computer to reset itself and turn off the check engine light.

No gas cap?

In vehicles with capless gas tanks, a check engine light related to the fuel system can still occur, even though there is no traditional gas cap. The light is usually triggered by issues with the fuel filler neck that connects the fuel tank to the fuel inlet. If there are obstructions, damage, or leaks in the filler neck, it can trigger a check engine light.

If the light remains on in your EcoSport even after addressing the gas cap issue, it is possible that there is another underlying problem that needs to be diagnosed.
