2004-2021Subaru WRX STI

P0244 is an OBD-II diagnostic trouble code meaning “Turbocharger Wastegate Solenoid B Range/Performance.” This code indicates the engine computer detected that turbocharger wastegate solenoid B is not performing within its expected range, so boost control is not behaving as commanded. The wastegate solenoid regulates boost pressure by controlling the wastegate; the computer compares actual boost to the target. When the solenoid's performance is out of range, this code sets. It can cause overboost or underboost, reduced power, and possible engine protection mode. This code is most commonly reported on 2004-2021 Subaru WRX STI, with repair costs ranging from $50 to $800.
