What happens if TPS is not calibrated?

If the TPS fails to send the proper data back to the computer, the correct fuel calculations can’t be made. With some engines, other sensors are able to compensate and provide a guess at how much fuel is needed, but this usually causes the engine to accelerate poorly or sporadically.
