If the TPS or Throttle Positioning Sensor goes bad on a 2004 GMC Envoy SUV, the car will have a very rough idle. The engine might stall frequently and the cruise control will not function properly. The car will also use much more fuel than is necessary.

What is a throttle body on a 2004 envoy?
Envoy throttle body is like the carburetor on earlier cars except it does not supply fuel to the engine. Fuel is delivered by the fuel injectors at each cylinder. It's only function is to supply a regulated amount of air to the engine with a motor driven flapper valve. It is mounted to the plastic intake manifold on the drivers side of the engine. It is only 1 part of the fuel control system. The TB also supplies feed back to the (PCM) powertrain control module (the computer). It has the (TPS) throttle position sensor built into the unit also. When your press on the gas pedal there is no mechanical connections to the throttle body like some earlier vehicles with carburetors. The (APP) accelerator pedal position sensor is connected the gas pedal and lets the PCM and throttle body know how much gas and air to supply to the engine. When my throttle body died it threw a code P1515.
