P210CThrottle Actuator B Control Motor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P210C is reserved for a low-side fault in the drive circuit of the second throttle motor, for example a grounded motor lead or an overloaded output stage. No manufacturer documents this code publicly. Makers with two throttles report such faults differently: GM's 23OBDG07 table files a bank 2 short to ground below 0.5 Ohm and driver overtemperature under P210A, and Ford's 2024 summary hangs all throttle B faults on P210A with failure-type bytes. CARB requires circuit faults of output devices to be detected, so where P210C is used it behaves like its bank 1 sibling P2102. Expect the second throttle to be switched off, rough running and reduced power. High-side faults would be P210D, open circuit P210A.
