Description of PID 91 – Accelerator Pedal Sensor Fault

PID 91 indicates that during operation, the Accelerator Pedal (AP) sensor input voltage is:‪

  • Erratic (91 02)
  • High (91 03)
  • Low (91 04)

The Accelerator Pedal is remotely mounted and connected to the DDEC-VCU. See Figure "Accelerator Pedal Installation" , Figure "Accelerator Pedal to DDEC-VCU Connectors" , and Figure "Accelerator Pedal to DDEC-VCU Connector" .‪
