P0244 OBD-II Trouble Code: Turbocharger Wastegate Solenoid A Circuit Range/Performance

Check Engine Light

P0244 code definition

Turbocharger Wastegate Solenoid A Circuit Range/Performance

What the P0244 code means

P0244 is an OBD-II generic code indicating that the engine control module (ECM) detected the Turbocharger Wastegate Solenoid A input circuit range or performance to be out-of-specifications when compared to the turbo boost sensor, manifold pressure sensor (MAP), or the barometric pressure sensor (BARO) at idle.

What causes the P0244 code?

  • The turbo boost pressure or MAP sensor is registering pressure in the intake manifold at idle, indicating that the wastegate did not bypass all the boost pressure quick enough, or all the way

  • The turbocharger wastegate solenoid is stuck on, causing boost pressure in the intake manifold

  • The wastegate solenoid ground side has an intermittent short on the control side, causing loss of solenoid control

What are the symptoms of the P0244 code?

  • The Check Engine Light will be illuminated and the code is set in the ECM memory
  • The engine turbo boost will be erratic and may cause engine to run rough or stall at idle
  • The engine may lack some power during acceleration if the solenoid has an intermittent short or open circuit

How does a mechanic diagnose the P0244 code?

  • Scans codes and documents the freeze frame data in order to verify the problem

  • Clears the DTC codes to verify whether the concern comes back

  • Checks the operation of the wastegate solenoid to see if it is capable of controlling vacuum to the wastegate leaking of vacuum when closed

  • Checks for any corrosion in the solenoid connection that may cause intermittent solenoid control issues

  • Checks the vacuum lines to and from the solenoid to the wastegate

  • Verifies that the wastegate is not sticking or binding

Common mistakes when diagnosing the P0244 code

Follow these simple guidelines to prevent misdiagnosis:

  • Verify that no codes for the boost pressure sensor are present, or repair them first
  • Verify that the wastegate is not stuck partly open or sticks when actuated

How serious is the P0244 code?

If the wastegate solenoid cannot shut off the wastegate completely, then you will have a boost condition in the intake manifold when the engine is at idle, which will cause the engine to run rough or stall at idle.

What repairs can fix the P0244 code?

  • Replacing the wastegate solenoid that is leaking vacuum at idle
  • Cleaning or replacing corroded wiring connections to the solenoid

Additional comments for consideration regarding the P0244 code

Code P0244 is triggered by the intake boost sensor indicating a pressure or low vacuum condition in the intake manifold, which is most likely caused by the solenoid not sealing off vacuum to the wastegate.
