Gmc Yukon 2003, Engine Light On What Are The Possibilities Of Malfunctions, When The Check Engine Light Comes On In A 2003 GMC Yukon?

What are the possibilities of malfunctions, when the check engine light comes on in a 2003 GMC Yukon? - gmc yukon 2003, engine light on

Well friend, could be one of hundreds of things. There is no simple way to check the error codes on the newer vehicles. You can buy a code reader relatively cheap to follow but no map to diagnostic and some experience, do not understand the situation, too. For example, you have a key oxygen sensor in May, but that could be caused by a faulty fuel injector, fuel pressure regulator, exhaust manifolds, and others, including the O2 sensor, it will be. I would adjust it to a repair shop and bite the bullet. Guidelines for parts of modern cars cost much more than it solved. They also show that the distributor or charge more per hour, which do not necessarily know what they are.

If the light is orange, the warning "Fire is .... go to the store soon, but not an emergency. The traffic lights are what worries

It depends on the distance to a certain extent. Probably the need for regular service. On some vehicles, the lamp lights up after the start of many, does not mean there is a problem that requires no maintenance. When was the last time check had a diagnosis? Or an update?

There is no good way to learn if you keep it plugged into the shop and to your computer. It could be either a bad O2 sensor for an engine problem. Trying to strengthen save your gas cap all the way, sometimes when the lid is not good that the check engine light come on when you do, whether it clicks 3 times worse.

I have a 2003 GMC Yukon and also my service engine light to activate all the time, which led to the shop and raised again during the day and the damn light. A week earlier company has never bothered. Give them time.

I own a repair shop, and only about 50 things that one is a simple one a gas cap loose, but there are many things that need that light on the way in which reality is impossible to say which might be of them, It covers an area of the car and make it scanned for free, one can say exactly what causes it, and as I said free, good luck, I hope that this assistance, art

Of course, you should check it out, but some cars, my Mustang, for example, the light check engine light when it is time for normal maintenance. Consult the manual that explains how to disable this option. But remember, regular maintenance to be done or determined by your dealer.
