That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.

The headlights on the envoy are the easiest parts of the car to repair. You just pull the two tabs at the top of the headlights, screw out the bulb containers and you are good to go

If you live near an Autozone, they can diagnose your code for free. This is gm's attempt to protect the engine from worse damage by limiting the power output of the motor...
it could be major, could be as minor as a gas pedal sensor...
get the code..

don't need any special tools, standard sockets sets, "C" clams is a must unless your a He-Man and wrench set, plyer or needle nose will do. I assumed being 2003 your rotor never have been turn and i recommend every time you change your bakes is good idea to have your rotor turn. reason is it will make your pad last lot longer, removed any vibration and better even wear on the pad and eliminate any squealing although is not necessary to do so. make sure you get extra break fluid to bleed the brakes. get your self 5 feet long smallest vacum rubber hoses and a glass jar to bleed your brake fluid in. the rubber vacum hose you going to use to fit on to the bleeding nipple and run the other end of line to your the glass jar to save the brake fluid when you bleed the brakes. when removing caliper, check inspect make sure the rubber seals around your piston look good and not crack or deteriorated. before applying new pad make sure you open the bleed valve to reduce the pressure by turning the bleed nipple counter clockwise and leave it open attach that rubber hoses to the nipple because you going to press on the piston back into it housing with the "C" clamp in order for new pad to fit. becareful not to damage the rubber seals around the piston. its going to take lots of effort to push that piston back in so be a bare with it if needs to. once the pad is back in make sure you keep the reservoir full with brake fluid and then bleed the brake. two people is a good idea to do brake. one will do the pumping the brake and holding it down and other will bleed the nipple. I bleed it 2-3 time will do the job. good luck!
