TP Sensor

RANGE 0-100 PERCENT
The PCM computes the Throttle Position (TP) from the TP sensor voltage input. The TP angle will auto zero to 0 percent at idle when the TP voltage is below 0.90 volt. The TP angle will read 100 percent at Wide Open Throttle (WOT).

RANGE 0.0-0.5 Volt
The PCM uses the Throttle Position (TP) sensor to determine the amount of the throttle demanded by the operator of the vehicle. The TP sensor reads between 0.36-0.96 volt at idle to above 4.0 volts at Wide Open Throttle (WOT).
