Throttle Position Sensor

THROTTLE POSITION INCREASE IN TPS VOLTAGE



10° Closed Throttle* 0 volts

20° .38 volts

30° .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 throttle blade is 10° open. When throttle is opened from idle to wide open throttle, the blade has traveled only 80°.

** The PCM considers an increase of 1.80 volts or more wide open throttle.

*** The PCM will shut off fuel injection if TPS voltage is 2.43 V above minimum.
