P2B82Wastegate Position Sensor B Circuit Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2B82 is the performance fault for the second electric wastegate, found only on engines with two turbochargers and position-controlled wastegates. No manufacturer documents this exact code publicly. By analogy with GM's checks for wastegate A (P2B81 in 19OBDG03D), the computer would flag lasting gaps between commanded and measured position, or a motor that needs abnormal current or duty cycle to hold its target. GM letters a parallel layout so that charger A sits on bank 1, which would put B on bank 2. Ford's patent US9243553B2 adds that heat changes linkage length and shifts the sensor reading, so a worn or binding linkage can mimic a sensor fault. Circuit faults on side B are P2ABA to P2ABC; the stuck-type counterpart is P0248.
- What you may notice
- Warning lamp with stored code
- Uneven or reduced boost, weaker pull
- Likely causes
- LikelyWastegate valve B or linkage binding from heat and deposits
- PossibleActuator B worn, gear or motor weak
- RareLoose linkage or retaining clip
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
