Could a Loose Fuel Cap Be Causing Your Check Engine Light?

That check engine light on your dashboard can be concerning, but the cause is sometimes surprisingly simple: a loose or faulty fuel cap. This small part does more than just prevent gasoline from splashing out; it seals your vehicle’s evaporative emission control (EVAP) system. As our video explains, when that seal is broken, it can trigger a warning light and even cause a noticeable fuel smell.

The EVAP system is designed to trap harmful fuel vapors, with the cap serving as its most vital seal. At Epoch Automotive, we often find that this is one of the first things to check when a customer visits with an illuminated warning light. It’s a quick and simple fix for a problem that can otherwise become a persistent hassle.

Don’t let a simple issue cause you unnecessary stress. Our technicians can quickly identify the problem with a professional check engine light diagnostics service. If a faulty cap is the culprit, we can replace it in seconds. To get to the bottom of that pesky warning light, call us at (267) 406-4922 for a quick and accurate diagnosis.
