P0244 Turbocharger/Supercharger Wastegate Actuator A Range/Performance

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

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.

Likely causes

Wastegate rod unhooked, retaining clip missing or linkage worn
Wastegate flap coked or sticking
Control hose to the wastegate can leaking, off or swapped; diaphragm torn
Wastegate solenoid mechanically stuck
Position sensor of the electric actuator not learned correctly

Symptoms

  • Check engine light on
  • Lack of power or surging, too high boost
  • Limp mode with reduced power
  • Rattle or whistle at the turbo possible
