Accelerator Pedal Position Sensor 2 Circuit Malfunction
2015-2021 Kia Sedona 3.3L V6
Description
The PCM has detected a malfunction in the Accelerator Pedal Position Sensor 2 circuit. This redundant sensor provides a backup throttle demand signal for safety. A fault in either APP sensor triggers reduced power mode.
Symptoms
- Check Engine Light
- Reduced power mode activated
- Engine limited to low RPM
- ETC warning light on
- Slow throttle response
Common Causes
- Faulty APP sensor 2
- Wiring or connector issue in APP sensor 2 circuit
- Corroded accelerator pedal connector
- Failing accelerator pedal assembly
- Reference voltage issue
Diagnostic Steps
- Monitor APP sensor 2 voltage through full pedal travel
- Compare APP sensor 2 with APP sensor 1 readings
- Inspect accelerator pedal connector for corrosion
- Check reference voltage at APP sensor 2
- Wiggle test wiring while monitoring
Repair Notes
Replace the accelerator pedal assembly if the APP sensor 2 is faulty.
