P2ABD Turbocharger/Supercharger Wastegate Actuator A Driver Current/Temperature Too High

Drive cycleNot required
Limp modePossible

P2ABD is raised by the output stage that powers the electric wastegate actuator of turbocharger A when it detects excessive current or overheating. Ford's 2020-23 gasoline summary groups it with P0243 in the wastegate A circuit check: the PCM's smart driver chip recognises a short to battery or ground and an open load on its own and reports within 0.4 s, and the stuck open/closed tests P25B3/P25B4 are only allowed when neither code is present. No Ford bulletin naming P2ABD was found. GM runs a comparable self-protection check on the EGR cooler bypass motor (P2AA5, H-bridge above 170 °C). A linkage that binds and stalls the motor, an internally shorted motor or chafed supply wires make the driver protect itself. P2ABE is the same fault on turbo B.

Likely causes

Wastegate flap or rod binding from soot, corrosion or heat so the motor stalls
Electric actuator motor shorted internally
Actuator supply wires chafed to ground or to each other
Driver stage in the PCM faulty

Symptoms

  • Check engine light on
  • Clearly reduced power because the wastegate is no longer driven
  • Stuck wastegate checks P25B3/P25B4 not run while the code is stored
