P0244 is a diagnostic trouble code (DTC) for "Turbocharger Wastegate Solenoid A Circuit Range/Performance". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Turbocharger Wastegate Solenoid A Circuit Range/Performance
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.
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
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
Follow these simple guidelines to prevent misdiagnosis:
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.
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.
