P0244Turbocharger/Supercharger Wastegate Actuator A Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- The wastegate lets exhaust bypass the turbine to limit boost; actuator A is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. P0244 means the actuator does not respond as commanded although its circuit is electrically sound, and manufacturers implement it differently. Subaru engines (Saab 9-2X) set it when manifold pressure exceeds an altitude-dependent limit – about 220 kPa absolute at sea level – for over 2 s, with the warning light at once. Stellantis documented it with a wastegate rod that had come off for want of a retaining clip. Older GM modules (Saab LDK, LLU) however use P0244 for an open solenoid circuit; newer GM and Ford systems do not use it and monitor function under P0234/P0299 or P25B3/P25B4.
- What you may notice
- Check engine light on
- Lack of power or surging, too high boost
- Limp mode with reduced power
- Rattle or whistle at the turbo possible
- Likely causes
- LikelyWastegate rod unhooked, retaining clip missing or linkage worn
- PossibleWastegate flap coked or sticking
- PossibleControl hose to the wastegate can leaking, off or swapped; diaphragm torn
- PossibleWastegate solenoid mechanically stuck
- RarePosition sensor of the electric actuator not learned correctly
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
