Check Engine Light Diagnosis At John's 4X4 Center In Boulder

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 you need to do is go to your 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.

Resist the temptation to have someone “clear” the codes to turn off your check engine light. This erases important diagnostic information that your technician 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 and have it checked out as soon as possible.
