ENGINE LIGHT STAYS ON. IT RUNS FINE - 2005 Mazda Tribute

    Why my Check Engine/Service/Check Engines Soon light comes on? The engine computer or PCM/ECM All modern vehicles have a computer or the ECM (Electronic Control Module) that controls the operation of the vehicle powertrain (the engine and transmission). The main purpose of this is to keep the engine running at top efficiency with the lowest possible emissions. With constantly growing demands for better fuel economy and new strictest emission regulations it's not very easy to achieve. The engine parameters need to be constantly and precisely adjusted according to various conditions such as speed, load, engine temperature, gasoline quality, ambient air temperature, road conditions, etc. That's why today's cars have much more electronics than in early days - there is a large number of various sensors and other electronic devices that help the vehicle computer or ECM to precisely control the engine and transmission operation and monitor emissions. The vehicle computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. To properly diagnose what is wrong, you need to take your car to a mechanic or a dealer. The technician at the dealership or a garage will then hook up the scanner to the car computer and retrieve the stored trouble code(s). Then he (she) will look it up in the service manual provided by a car manufacturer. The service manual contains the list of possible codes (about few hundreds) and describes what each code means and what needs to be tested. The code itself doesn't tell exactly what component is defective - it only indicates where to look, what engine parameter is out of normal range. The technician will have to perform further testing to pinpoint a defective part.

Doesnt sound like much of a problem some vechiles put on the light for matenience reasons. try unhooking the battery positive leave it disconected for 15-20 mins and reatach it. this should clear any active codes. start you vechile if it comes on again you will have to get a code reader or bring it to a garage to see why its on. but if it runs fine pffff
my lights been on for a long time and still runs fine

Check engine light stays on all the time, but car runs fine?


Well, the engine management system has something wrong. Pull the codes and explore the code(s) given.
Car running fine with the check engine indication is not unusual. Something is wrong, get after it.

Check engin light stays on. Starts fine runs


Most common cause of engine lights is either an air fault such as air flow meter or air mass sensor. there are others but if the car is driving fine then most likely an air fault.

Check the air sensor sometimes they just need a clean up rather than replacement.
Let me know if you need more info.

Most local parts stores like Autozone or Advance auto will check the trouble codes for free and help you get the parts you need to fix whatever is causing the engine light to come on.
