Important Facts Mount Vernon Drivers May Not Know About Their Check Engine Light

Last Updated: Jul 01, 2025

The Check Engine light might come on in your vehicle. It's an amber colored light that shows on your dashboard. In newer vehicles it might just be a problem with your gas cap not being screwed on tight enough (or a worn gas cap), causing the vehicle to fail the self-diagnostic evaporative emission test. All Mount Vernon drivers need to do is go to their gas cap and verify that it is tight. If that was the problem, the light will turn off and everything will be fine within one or two days.

At Martin's Auto Center, we advise Mount Vernon drivers to resist the temptation to have someone “clear” the codes to turn off your vehicle check engine light. This erases important diagnostic information that your friendly and knowledgeable Martin's Auto Center service advisor needs to diagnose the underlying problem for the Check Engine light – and any other pending problems that may be stored in the computer.

If the problem is still there - you still see the light - bring your vehicle in to Martin's Auto Center in Mount Vernon and have it checked out as soon as possible.
