Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation
on 2007 Kia Sedona 3.5L V6 · FWD
What this code means
The dual throttle position sensors are reporting conflicting values, indicating a fault.
Symptoms
- Limp mode
- Reduced power
- Check engine light
- Erratic throttle response
Common causes
- Failed TPS (built into throttle body)
- Connector corrosion
- Intermittent wiring
- 5V reference circuit fault
Diagnostic steps
- Check TPS sensor A and B voltages
- Verify 5V reference
- Wiggle test wiring
- Check connector pins
Repair notes
Replace throttle body assembly (TPS is integrated). Check 5V reference shared with other sensors.
