Electronic Throttle Body Throttle Position Sensor

WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2020 Lincoln Navigator, 2020 Lincoln Nautilus, 2020 Lincoln MKZ, 2020 Lincoln Corsair, and 2020 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.

There is one reference voltage and one signal return circuit between the PCM and the electronic throttle body throttle position sensor. The reference voltage and the signal return circuits are shared with the reference voltage and signal return circuits used by the accelerator pedal position (APP) sensor. On some vehicles, there is one digital throttle position signal circuit. For all others, there are 2 analog throttle position (TP) signal circuits for redundancy. The redundant analog TP signals are required for increased monitoring reasons. The first analog TP signal (TP1) has a negative slope (increasing angle, decreasing voltage) and the second TP signal (TP2) has a positive slope (increasing angle, increasing voltage). The TP2 signal reaches a limit of approximately 4.5 volts at approximately 45 degrees of throttle angle.
