DTC P1125: Accelerator Pedal Position Sensors Out Of Range: Description

Accelerator Pedal Position (APP) sensors are mounted on accelerator pedal of Throttle Actuator Control (TAC) module assembly. 3 individual APP sensors are contained within one housing. Three separate low reference and 5-volt reference circuits are used. If only one APP sensor DTC is set, redundant APP systems allow Electronic Throttle Control (ETC) system to continue operating normally. DTC sets if Powertrain Control Module (PCM) detects a condition with more than one APP sensor. One APP sensor diagnostic trouble code (DTC) will not cause REDUCED ENGINE POWER message to be displayed on Driver's Information Center (DIC). 2 APP sensor DTCs for same sensor also will not cause message to be displayed. However, if 2 or more DTCs are set involving more than one APP sensor, this DTC will set and REDUCED ENGINE POWER message is displayed.
