What percentage should my throttle position read?
If the TPS has a worn spot, most likely it will be between 0 and 20 percent throttle opening. Try holding the throttle between 0 and 20 percent to see if you get a steady reading. If the reading suddenly drops while holding the gas pedal or throttle linkage steady, it may indicate a fault with the sensor.
When does the throttle position sensor read 19%?
All of the sensor readings seem to be accurate, with the exception of the throttle position sensor, which reads 19% when the car is at idle with my foot off the gas. When I accelerate, the throttle position climbs correspondingly.
Which is the correct position for the throttle?
The ECU will use voltage as a reference to a bad TPS, not position. 5v usually for a bunk sensor (eg, a short). You calibrate voltage to its relative position. There is some play, generally, to adjust it physically. While the voltage is within a range, the position of the throttle can certainly be 0-100. 0= your foot’s off the gas.
How can I Reset my throttle position sensor?
Reprogramming or resetting your sensor can sometimes solve these issues. This step can also be necessary when you install a new sensor. The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.

What should my TPS be with no throttle?
It depends on the vehicle, the TPS position is usually within a range, some vehicles start at 10tps with no throttle input and stop at 85tps at full throttle input. It’s actually in my experience uncommon to see 0% tps for no throttle and 100% tps for full throttle as the computer typically uses those extreme numbers to indicate a bad TPS.
Can a throttle be in the 0-100 range?
While the voltage is within a range, the position of the throttle can certainly be 0-100. 0= your foot’s off the gas. The IAC generally can have enough leeway to deal with things in a 0 position condition. As others have mentioned, there may be cold start circuits to open the throttle electronically or mechanically until it’s properly warm.
