Check Engine Light Explained

Modern vehicles are equipped with a performance monitoring system with sensors placed among primary systems. The check engine light illuminates when the onboard diagnostic system detects a performance problem with a primary system or component. The check engine light signals that there is a problem but does not identify the problem nor what to do. Fixing the problem will require a check engine light diagnosis and corrective maintenance. Getting a check engine light diagnosis and corrective maintenance promptly is the best decision because this is the only way to fix the issue and contain the risks associated with it.

Free Check Engine Light Diagnosis at Pappas Toyota in St. Peters, MO

Service begins with a certified technician and specialized onboard diagnostic code reader. This will pull the trouble code from the onboard computers. The code will tell the technician where the problem exists. Depending upon the code, we might visually inspect the trouble part for confirmation, and to know what corrective maintenance will fix the problem. Check engine light diagnosis usually ends in a referral to the corrective service needed to fix the problem.


Is the Check Engine Light an Emergency? Solid vs Flashing Light

Check engine lights have countless causes ranging from very simple to moderate. The check engine light is usually solid but can flash under some circumstances. It is important to remember that a solid check engine light does not signal an emergency, you don’t need to stop immediately, and you don’t need a tow truck. Simply get the check engine light diagnosed soon. Flashing check engine lights are an emergency that signals a severe problem exists. In this case, you should pull over into a safe position and turn the engine off. Driving with a flashing check engine light can lead to catastrophic damage.
