Throttle Position Sensor

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.
