Throttle Position Sensor: Specifications
THROTTLE POSITION .................................................................................................................................... INCREASE IN TPS VOLTAGE
10° Closed Throttle* ....................................................................................................................................................... 0 volts
20° .................................................................................................................................................................. 0.38 volts
30° .................................................................................................................................................................. 0.75 volts
45° Half Throttle ........................................................................................................................................................ 1.31 volts
58° ................................................................................................................................................................ 1.80 volts**
75° ............................................................................................................................................................... 2.43 volts***

*
At idle the throttle blade is open 10°. When the throttle is moved from the idle position to the "wide open" position, the blade is rotated 80°.
**
The PCM recognizes a TPS voltage of 1.80 volts or more over idle position voltage as "Wide Open Throttle" (WOT).
***
If the TPS voltage sensed at the PCM rises 2.43 volts or more from idle position voltage, the PCM shuts off fuel injection.
