Why does the throttle position sensor provide VTA 1 and VTA2 signals?

The throttle position sensor has two sensor circuits: VTA 1 and VTA2, and each circuit sends out a signal. VTA 1 is used to detect the throttle opening, and VTA2 is used to detect the fault of VTA 1. The sensor signal voltage is proportional to the throttle opening, ranging from 0 to 5 volts.
