P0244Turbo/Super Charger Wastegate Solenoid 'A' Range/Performance

P0244 means the engine computer has detected that the turbocharger or supercharger wastegate solenoid circuit 'A' is not performing within its expected range, typically because the solenoid's electrical response or the resulting boost control deviates from commanded values. The powertrain control module monitors the solenoid's feedback and the turbo system's boost behavior, and it sets this code when the solenoid's range or performance falls outside calibrated limits.

Symptoms you may notice

  • Illumination of the check engine light, often with no other noticeable symptoms
  • Reduced engine power or a limp mode condition due to overboost protection
  • Poor acceleration or sluggish throttle response from lost boost control
  • Audible turbo flutter or surge noises during acceleration or deceleration
  • Decreased fuel economy because the engine management system runs richer or limits boost
  • Intermittent boost spikes followed by sudden power cut, especially under load

Common causes, most likely first

  1. Faulty wastegate solenoid 'A' that is stuck, weak, or electrically degraded
  2. Damaged, corroded, or disconnected wiring and connectors at the solenoid or PCM
  3. Vacuum or pressure lines to the wastegate actuator that are cracked, split, or incorrectly routed
  4. Sticking or seized wastegate actuator linkage or flapper valve
  5. Boost pressure sensor or MAP sensor providing inaccurate feedback to the PCM
  6. PCM software calibration issue or internal driver fault for the solenoid circuit
  7. Restricted or leaking charge air system components affecting boost control authority

How to diagnose and fix it

  1. Inspect the wastegate solenoid connector and wiring for corrosion, chafing, or loose pins, and repair as needed
  2. Check all vacuum and pressure hoses between the solenoid, wastegate actuator, and turbo for cracks or disconnection
  3. Test the solenoid's electrical resistance and compare to the manufacturer's specification, and verify it clicks when commanded
  4. Command the solenoid with a scan tool and observe boost pressure or actuator movement to confirm range and performance
  5. Verify that the wastegate actuator moves freely and that the flapper valve is not stuck or carbon-fouled
  6. Compare boost pressure sensor readings to actual boost with a mechanical gauge to rule out sensor error
  7. Replace the wastegate solenoid if electrical and mechanical checks pass but performance remains out of range, then clear and re-test

Wastegate solenoid range faults often misdiagnosed

  • A common misdiagnosis is replacing the turbocharger when the actual fault is a five-dollar vacuum hose that has softened and collapsed under boost.
  • The code can be set by a sticking wastegate actuator that prevents the solenoid from achieving the commanded range, even though the solenoid itself is electrically perfect.
  • Incorrectly routed vacuum lines after a repair or engine service can cause this code without any failed component, so always verify routing against the underhood diagram.
  • Some vehicles set P0244 intermittently due to a marginal boost pressure sensor that reads slightly off, and the solenoid gets blamed because it is easier to access.
  • A dirty or contaminated solenoid valve from oil mist in the intake tract can cause range performance faults that clear temporarily after cleaning but return without a proper fix.

Can I keep driving with P0244?

You can usually drive the vehicle with this code, but avoid heavy throttle and sustained boost because the turbo system may overboost or underboost unpredictably. If the vehicle enters limp mode or you hear abnormal turbo noises, have it inspected promptly to prevent damage.

Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
