Check Engine Light On?
Posted on:Tuesday, December 3, 2013

If your check engine light is illuminated, it's best to take it in for diagnostic testing at anauto repair or transmission repair shop. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the way your car is running.

The check engine light is part of your vehicle's onboard diagnostics system. Computers have control and monitor vehicle performance, regulating such variables as engine speed (RPM), fuel mixture, and ignition timing, and even tell the automatic transmission when to shift.

When the electronic-control system finds a problem it cannot adjust, the computer turns on a yellow warning indicator and stores a trouble code in its memory. These diagnostic trouble codes help identify the probable source of the problem, such as a malfunctioning sensor or a misfiring engine and can be read with a scan tool or diagnostic computer. Vehicle manufacturers originally used the onboard diagnostics system to help technicians pinpoint and troubleshoot malfunctions.

Continuing to drive your vehicle with the check engine light on without having your vehicle inspected could lead to major damage to your vehicle, and even leave you stranded. It is vital that you bring your car to a repair shop to have your computer scanned. At Reliable Transmissions, we offer this service to our customers for free in order to help them gain more information on what may be wrong with their vehicle.
