Electronic Throttle Body Throttle Position Sensor (ETBTPS)

ENGINE CONTROL COMPONENTS

Electronic Throttle Body Throttle Position Sensor (ETBTPS)
The ETBTPS has 2 signal circuits in the sensor for redundancy. The redundant ETBTPS signals are required for increased monitoring. The first ETBTPS signal (TPS1-NS) has a negative slope (increasing angle, decreasing voltage) and the second signal (TPS2-PS) has a positive slope (increasing angle, increasing voltage). The 2 ETBTPS signals make sure the PCM receives a correct input even if one signal has a concern. There is 1 reference voltage circuit and 1 signal return circuit for the sensor that are shared with the reference voltage circuits and signal return circuits used by the APP sensor. For additional information, refer to Torque Based Electronic Throttle Control (ETC). Description and Operation
