Check engine light codes and information.
Before we get into the gory details you must know that in the average car there are over 300 reasons ( or codes ) that can cause the check engine light to illuminate. Some serious, some not so serious. Before you jump to conclusions be sure to have your car scanned by a professional to determine if the check engine light is on for a serious reason. If the check engine light is blinking this indicates an engine misfire and the car should be stopped immediately and taken to a repair facility to be diagnosed. Driving the car on a blinking check engine light can do internal damage to engines and emissions components. Below is a generic list of codes and their meaning in today's vehicles.

  • Top 5 most seen codes:

    P0171 -System too lean
    Usually caused by a air leak in the engine.

    P0420 - Catalyst System Efficiency Below Threshold
    Usually caused by aging catalytic converter or exhaust leaks prior to the catalytic converter.

    P0455 - Evaporative Emission Control System Leak Detected
    Usually caused by the gas cap being loose, not tightened all the way or a bad purge vent valve.

    P0300, 301-308 - cylinder Random/Multiple Cylinder Misfire Detected
    Usually caused by poor spark, the car needing a tune-up, spark plugs or bad fuel injector(s).

    P0300, 301-308 - cylinder Random/Multiple Cylinder Misfire Detected
    Usually caused by poor spark, the car needing a tune-up, spark plugs or bad fuel injector(s).

    P0141 - 02 Sensor Heater Circuit Malfunction
    Usually caused by old 02 sensors with over 40,000 miles on them. 02 sensors are the most commonly replaced sensor on all vehicles. These mostly affect gas mileage but not how the car drives (in some cases).
