All About Check Engine Lights

Check engine lights are on the dashboard to signal the driver when the onboard diagnostic system senses a problem. The onboard diagnostic system has sensors positioned throughout primary systems, constantly monitoring air quality, fluid levels, temperatures, electronics, and more. The onboard diagnostic system illuminates the check engine light when a problem is detected. Although the system’s computer stores a trouble code related to the problem, the driver will only know that a problem has been found. A check engine light diagnosis is necessary to investigate the trouble code and verify the problem for accurate and efficient repairs.

Certified Toyota Check Engine Light Diagnosis

We know that many auto part franchises offer free check engine light scans, but rest assured that free trouble code scans fall significantly short of a certified Toyota check engine light diagnosis service. Our factory-trained technicians are only getting started when the trouble code is extracted from the onboard diagnostic system. We use the trouble code to investigate the problem, including a thorough inspection for verification that lays the groundwork necessary for an accurate repair referral.

Solid vs. Flashing Check Engine Lights

Most check engine lights are solid, signaling a minor issue has been detected. Solid check engine lights are non-emergency issues that are safe to drive, but scheduling a prompt check engine light diagnosis is recommended as automotive problems only worsen with additional miles/time. Flashing check engine lights signal more severe problems, and driving is not recommended. The best-practice recommendation is to stop in a safe position and call us to discuss the check engine light and other driving symptoms.
