P2ABE Turbocharger/Supercharger Wastegate Actuator B Driver Current/Temperature Too High

P2ABE is the turbo B counterpart of P2ABD: the output stage driving the second electric wastegate actuator signals overcurrent or thermal overload. It therefore applies only to twin-turbo engines with two electric actuators, such as Ford's EcoBoost V6. Ford's summary treats it together with P0247 as the B circuit check, with the fault detected inside the smart driver chip and a monitoring time of 0.4 s; the functional checks P25B5/P25B6 are blocked while either code is stored. No public bulletin naming P2ABE turned up. A rod seized by corrosion, a shorted motor winding or a harness pinched against the turbo can make the driver shut down to protect itself. Because the bank 2 flap is then left unpositioned, the PCM is likely to limit boost on that side.

Likely causes

Wastegate B rod or flap seized by corrosion or heat
Shorted winding in electric actuator B
Actuator harness pinched against the turbocharger

Symptoms

  • Check engine light on
  • Reduced power, uneven boost between the two banks
