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.
