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***
90° Wide Open Throttle 3.00 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.
