My check engine light just came on on my 2005 GMC Yukon XL with 106,000 miles. I had a premium oil change on Monday and all fluid levels were checked and OK. Never had light come on before. Some suggestions as to what is the cause? Truck does not overheat and all levels indicate adequate.
Check engine light means, that your engine computer pick up a bad signal from one of your engine sensor, the engine will still run good because of back up sensor's,need to have a code reading done to find out what's wrong or it will damage other sensor's, you can go to any auto parts or autozone where they can do a code reading at no charge, get back to us with the code number, so we can help you diag. your trouble code.
