Electronic Throttle Body Throttle Position Sensor (ETBTPS)

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2021 Lincoln Navigator, 2021 Lincoln Nautilus, 2021 Lincoln Corsair, 2021 Lincoln Aviator, and 2021 Ford Transit-350 HD. However, it is still accessible from the selected car via links, so may be relevant.

On some vehicles, the ETBTPS has one digital signal output from the sensor. There is one reference voltage circuit (ETCREF) and one signal return circuit (ETCRTN) for the sensor dedicated to the ETBTPS. For additional information, refer to Torque Based Electronic Throttle Control (ETC).

For all others, the ETBTPS has two analog signals output from the sensor. The first ETBTPS signal (TP1) has a negative slope (increasing angle, decreasing voltage) and the second signal (TP2) has a positive slope (increasing angle, increasing voltage). There is one reference voltage circuit (ETCREF) and one signal return circuit (ETCRTN) for the sensor shared with the reference voltage circuits (APPVREF1 and APPVREF2) and signal return circuits (APPRTN1 and APPRTN2) used by the APP sensor. For additional information, refer to Torque Based Electronic Throttle Control (ETC).
