P210AThrottle Actuator B Control Motor Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Throttle actuator B only exists on engines with two electronic throttles, typically one per cylinder bank. P210A reports an electrical fault, mainly an open line, in the drive of that second motor. GM's 2023 table 23OBDG07 checks the bank 2 H-bridge just like bank 1: open load above 200 kOhm (0.8 s), driver overtemperature and short to ground below 0.5 Ohm, each one trip. Ducati links P210A to the rear-bank throttle motor of its V4 and points to moisture in the ECU connector. Ford's 2024 summary uses P210A as base code for all faults of its second throttle body. The engine runs on reduced power. Bank 1 is P2100; low/high circuit faults are P210C/P210D, position errors P210B.
- What you may notice
- Reduced power, one bank breathing poorly
- Engine warning lamp on
- Rough running or limp mode
- Likely causes
- LikelyMoisture or corrosion in the throttle B or ECU connector
- PossibleBroken motor wire to throttle body B
- PossibleOpen winding in throttle motor B
- RareFaulty bank 2 output stage in the ECU
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
