engine will proberly only idle
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.
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.
The throttle position sensor, TPS, tells the engine control module,ECM where the throttle blade is. It is the primary way that the ECM knows what you want out of the engine. There is a backup system if the TPS fails, but it is not as efficient as the TPS. So what does happen. The engine will not be as responsive to the throttle as it should be. When you accelerate there may be a pause while the ECM realizes what you did. If you let off the of the accelerator the engine may take a few moments to return to idle or may idle rough and have a minor surge. It will ultimately return to idle. The engine will still run, but will be sluggish and lose its pep.
If a transmission speed sensor fails, the transmission will default to second gear.
When the Carbon monoxide (CO) detector fails in a gas dryer, the alarm sensor malfunctions.
The ignition timing will be off causing misfiring among other problems.
Just like a old TV Wear and tear, gets old then fails. The sensor stops building voltage potential
Hesitation Definition: When the throttle peddle is pressed the engine fails to respond, and may stall. For this to be true it is idling correct. No, a failed, stuck or gummed up IAC will not cause the hesitation. The gummed up may if it has blocked any of the small passages in the throttle body. It is much more likely you have a bad plug, plug wire, Oxygen sensor, Temp sensor, Bad MAP sensor or other problem.

as the crank spins around there is a magnet on it, and the sensor pics up a signal off of it to detect that the crank is in motion. If the sensor fails it will not send a signal to the computor, and that will cause the ignition system to shut down, so you will not have spark.
Normally if the crank sensor fails while running,the engine can keep running with just a working camshaft sensor.
When MBR fails then the operating system will not load.
