How does the p2138 Buick accelerator pedal position sensor work?

The APP sensor 1 sends a signal from the sensor to the ECM indicating the accelerator pedal position. The ECM actuates the throttle plates based on this information. If the ECM detects that the APP sensors are not within a predicted value from each other, DTC P2138 sets.

What causes a P2138 code?

Can I drive with a bad throttle position sensor?

What is the p2138 code on a Nissan?

I’ve attached pictures. So I’m wondering could it be something else? I’ve ordered the pedal sensor its about $200.

What does the p2138 Nissan accelerator pedal sensor circuit do?

P2138 NISSAN Description. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the accelerator pedal and feed the voltage signals to the ECM.
