Accelerator pedal normal sensor open circuit, or short circuit to ground.
• Check wiring (to accelerator pedal sensor) • Check connectors (to accelerator pedal sensor) • Check accelerator pedal sensor • Measure the sensor voltage between signal and ground • Check accelerator pedal mechanism
What you'll see
Accelerator pedal will not function as long as the fault is present. Accelerator pedal position information sent on the CAN-bus is labeled with an error indicator. Accelerator pedal kickdown information sent on the CAN-bus is labeled with an error indicator (if vehicle is equipped with kickdown). Downhill speed control is disabled Adaptive Cruise control is disabled Collision Mitigation (warning and/or brake assist) will be deactivated.
System reaction
Amber AEB malfunction Amber Cruise Control malfunc.
Diagnostic depth
Impermissible signal from the accelerator pedal normal sensor. The sensor voltage level is too low. The accelerator sensor has an open circuit, or is short circuit to ground.
• Defect wiring - open circuit on accelerator pedal signal (pin C11) - open circuit on accelerator pedal sensor supply (pin C29) - short circuit to ground • Defect connectors • Defect accelerator pedal sensor (potentiometer) • Mechanically defect accelerator pedal mechanism (causing accelerator pedal sensor to reach an impermissible position)
