Accelerator Pedal Position Sensor 1 Circuit Malfunction

2015-2021 Kia Sedona 3.3L V6

High SeverityPowertrain

Description

The PCM has detected a malfunction in the Accelerator Pedal Position Sensor 1 circuit. This sensor provides primary throttle demand input to the PCM for electronic throttle control.

Symptoms

  • Check Engine Light
  • Reduced power mode
  • Throttle response limited
  • Engine may idle only
  • ETC warning light

Common Causes

  • Faulty APP sensor 1
  • Wiring damage or corrosion in APP sensor circuit
  • Loose accelerator pedal connector
  • Faulty accelerator pedal assembly
  • 5V reference circuit issue

Diagnostic Steps

  1. Monitor APP sensor 1 voltage through full pedal travel on scan tool
  2. Check for smooth voltage sweep without dropouts
  3. Inspect APP sensor connector and wiring
  4. Verify 5V reference voltage at sensor
  5. Compare APP sensor 1 and 2 readings

Repair Notes

Replace the accelerator pedal assembly if the internal APP sensor 1 is faulty.
