SOURCE: FAILED EGR VALVE
The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. This results in a cooler, more complete burn of the fuel which decreases you car's noxious emissions by prohibiting the formation of some harmful gases.
The EGR valve is vital to your car's emission controls.
When the EGR valve goes bad, it must be replaced - it cannot be repaired.
The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on accelertaion.
The only short term problem is a decrease in gas mileage - but it should really be replaced before sensors become sooted or your cat. convertor gets overworked prematurely.

SOURCE: check engine light on
You cannot reset the check engine light any other way than using a scan tool. Some auto parts stores will scan the vehicle for free then at least you will know the area of the fault.

you have to know what the code is that your truck putting out your truck has 4 O2 sensors. the trucks computer is smart and the code will tell you witch one is bad but if you replace just one the next one on the same exhaust pipe will probley go bad so its safe to replace all four. the draw back to replaceing all of them is thay cost about 80 bucks for one ACDelco O2 sensor. It has to be done before it will pass Emissions. not a hard part to change about a 7/8 open end wrench will take it off. have fun.
