P1271 Meaning

The Accelerator Pedal Position (APP) sensors are located within the Throttle Actuator Control (TAC) module assembly. The TAC module assembly is mounted to the accelerator pedal bracket. There are 3 individual APP sensors within the TAC module. Three separate signal circuits, low reference circuits, and 5-volt reference circuits are used in order to determine the accelerator pedal position. The APP sensor signal voltages increase when the accelerator pedal is depressed.
