In all probability not. If you have a check engine light on then you will need to have it scanned for codes. If the code shows a component, such as the TPS, it DOES NOT mean that is defective. It only means the problem lies in that area. That is what you pay a technician to let you know. It is cheaper to know what is the problem, than to throw parts at the car.
That is one possibility for that complaint
it can cause the car not to start.
Yes, my grand am had that problem a week ago, changed out the sensor and it runs like a champ!
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
A failing throttle position sensor will cause idling problems when the car is warm. The failing sensor can also cause the car to stall when idling.
Hesitation can be caused by several things: 1. A faulty throttle position sensor might cause hesitation. 2. A faulty MAP or MAF sensor might also cause hesitation. 3. A problem with the engine control module might cause hesitation.
It is possible but not likely.
The possibilities can be many. It can range from a malfunctuioning fuel pump, to a bad throttle position sensor, to faulty fuel injectors. First I would check the throttle position sensor since this is the cheapest part, and also the easiest to replace. The throttle position sensor tells the computer how much air and fuel to put in the engine. If it is messed up it can cause hesitation, stalling, transmission buckoing, etc...

Throttle Position Sensor (TPS) or Mass Air Meter
A bad throttle position sensor, on your 1991 Saturn, will cause the engine to run rough when it is idling. The engine will run normally at higher speeds.
