What Does P0244 Mean?
The turbocharger wastegate solenoid A is not performing within expected parameters. While the electrical circuit is functional, the actual wastegate response does not match the ECM's commanded position. This typically means the solenoid is sluggish, partially stuck, or the wastegate mechanism is binding. The driver may notice inconsistent boost pressure, surging, or power fluctuations.
Common Causes
30%
Carbon buildup or debris causing the wastegate actuator to stick or bind
25%
Weakened or leaking vacuum hose to the wastegate actuator
20%
Degraded wastegate solenoid with intermittent operation
15%
Worn wastegate actuator diaphragm allowing vacuum leakage
10%
Exhaust leak near the turbocharger affecting wastegate pressure balance
Diagnostic Steps
1
Monitor actual boost pressure vs. target boost on live data during acceleration — note whether boost overshoots, undershoots, or oscillates around the target. This reveals whether the wastegate is sticking open or closed.
2
Inspect the wastegate actuator arm for free movement. Push the arm by hand — it should move smoothly with consistent spring tension. If it is stiff, seized, or has excessive play, the actuator or wastegate valve is binding.
3
Apply vacuum to the wastegate actuator directly using a hand vacuum pump (typically 10-15 inHg to fully open). The actuator should move smoothly and hold vacuum for at least 30 seconds. A rapid vacuum drop indicates a torn diaphragm.
4
Inspect all vacuum hoses between the solenoid and the wastegate actuator. Pinch off suspect hoses one at a time and observe boost control changes on live data.
5
Command the wastegate solenoid on/off using scan tool bi-directional controls while monitoring boost pressure — the wastegate should respond within 1-2 seconds of the command change.

The most common cause of P0244 (Turbocharger Wastegate Solenoid A Range/Performance) is: Carbon buildup or debris causing the wastegate actuator to stick or bind
Typical repair costs for P0244 range from $150 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Inconsistent boost control can lead to overboost events or drivability issues. Drive conservatively and avoid full-throttle operation. If boost is spiking significantly above target, stop driving to prevent catastrophic engine damage. Underboost is less dangerous but still requires repair.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0244 to identify the root cause.
