P2ABDTurbocharger/Supercharger Wastegate Actuator A Driver Current/Temperature Too High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- 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
- Likely causes
- LikelyWastegate flap or rod binding from soot, corrosion or heat so the motor stalls
- PossibleElectric actuator motor shorted internally
- PossibleActuator supply wires chafed to ground or to each other
- RareDriver stage in the PCM faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
