Check Engine Light

Why the Check Engine Light Is On

The engine, transmission, drivetrain, evaporative, and emissions system – the Check Engine light monitors them all. Any sensor, wire, or component could be the root cause of the warning light coming on. It could be due to:

• A faulty oxygen sensor that measures emissions in the exhaust.
• An engine misfire caused by a fouled spark plug.
• A loose gas cap.
• A software concern in an onboard computer.
• Or any other of dozens of causes.

The diagnostic trouble codes (DTCs) will need to be checked and the underlying cause corrected to restore your faith in your automobile. It’s definitely a job for an experienced, well-trained technician.

Other Warning Lights to Watch

Along with the Check Engine light, other warning indicators can be illuminated. A fault in the anti-lock braking (ABS) system can cause the ABS or traction control light to come on. An ailing alternator or inadequate wiring can contribute to a battery light showing up. Low fluid or an electrical failure could cause a power steering warning.

Some lights are for information only, designated by their green or blue color. For warning indicators that are yellow or red, it’s a great idea to have your vehicle checked as soon as possible to prevent ongoing issues that could leave you stranded.
