Accelerator Pedal Position Sensor 1 Circuit Malfunction
2022-2024 Kia EV6 Electric
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
- Monitor APP sensor 1 voltage through full pedal travel on scan tool
- Check for smooth voltage sweep without dropouts
- Inspect APP sensor connector and wiring
- Verify 5V reference voltage at sensor
- Compare APP sensor 1 and 2 readings
Repair Notes
Replace the accelerator pedal assembly if the internal APP sensor 1 is faulty.
