The throttle position sensor is on the throttle body at the end of the throttle shaft.
The 2002 Chevy Impala throttle position sensor can be found on the top of the engine. The throttle position sensor will be near the injector fuel pump.
The throttle position sensor is on the throttle body opposite of where the cables attach.
On the throttle body.
According to my factory service manual the voltage at the throttle position sensor should vary from about 0.5 volts in the idle position to 5.0 volts in the wide open throttle position.
On the Throttle body!
The 1997 Chevy 1500 throttle position sensor is located on the firewall in the engine compartment. The throttle position sensor will be in the center of the firewall.
its located on the side of the throttle body
It is on the side of the throttle body opposite the throttle cable.
The throttle position sensor is actually apart of the throttle plate actuator assembly and must be replaced as a unit.
Assuming you mean the throttle position sensor. The throttle position sensors tells the engine computer when the throttle position has changed, it adjusts fuel flow to match the throttle opening. If the throttle position sensor fails then the engine computer has to depend only on the MAP sensor to define air flow thus how to adjust the fuel flow. I would expect then that response time would be slower than when the throttle position sensor works correctly. On a Chevy Celebrity it might also turn on the check engine light and post either a code 21 or a code 22.
Attached to the side of the throttle body.
