P2AD3: Throttle/Pedal Position Sensor/Switch A/G Voltage Correlation
Standardized SAE J2012 code · P2Axx codes
What does P2AD3 mean?
The voltage signals of throttle/pedal position channels A and G do not correlate within the calibrated tolerance. One sensor element drifted or harness shows offset between channels.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- Check engine light on
- Reduced throttle response, possible limp mode
- Hesitation or surging
- Idle too high or too low
Common causes
- High Sensor channel A or G drifted
- Medium Harness offset between channels
Likelihood is a general estimate across vehicles; your make and model may differ.
