What does Peugeot 207 fault code p0223 mean?

Throttle/Pedal Position Sensor/Switch B Circuit High

Throttle/pedal position sensor/switch B circuit high.

Category: fuel or air

Detailed meaning: In the Electronic Throttle Control (ETC) system, the function of the accelerator pedal position (APP) sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of an electrical signal, which serves as a reference for the throttle actuator to control the throttle opening. This fault code indicates that the circuit voltage of accelerator pedal position sensor B has been higher than the calibrated maximum value (4.65V) for a set period of time. The fault causes include sensor interface fault, positive short circuit, sensor fault, electronic control module (PCM or ECM) fault, etc.
