TP Angle

Range 0 to 100%
The VCM computes the TP Angle from the TP signal voltage input. This is an indication of throttle blade angle demanded by the operator. The TP Angle should read 0 percent at idle. At 0 percent, the TP voltage will read below 0.90 volts. The TP Angle should read 100% at Wide Open Throttle.
