What problems does a bad TPS cause?
What happens when the throttle position sensor goes bad? If your sensor goes bad, then the car’s computer will receive inaccurate readings about the position of the accelerator pedal. This can cause your car to be sluggish, start jerking, have trouble shifting gears, or even stall in some cases.
How do you reset the throttle position sensor on a Toyota?

How do you know if your throttle position sensor is bad?
Test the TPS using a digital multimeter. Make sure that it’s still working and, if necessary, visually inspect and test the wires and connector. If the sensor tests OK, erase the code. If it comes back or you notice a performance issue.
Does throttle position sensor affect transmission?
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.
How can you tell if throttle position sensor is bad?
