P0244 code means Turbocharger Wastegate Solenoid A Range/Performance. Learn the causes, symptoms, severity, location, repairs, diagnostic steps, costs, and related codes.
Fault Code Description
P0244 = Turbocharger Wastegate Solenoid A Range/Performance.
Code type: Generic OBD-II Powertrain Code.
System: Turbocharger wastegate control.
Component: Turbocharger Wastegate Solenoid A.
P0244 means the ECM/PCM has detected that the wastegate solenoid A control system is operating outside its expected range or performance characteristics.
P0244 does not automatically mean that the turbocharger itself has failed. The problem may involve the wastegate solenoid, vacuum or boost-control system, wiring, electrical connectors, hoses, wastegate actuator, mechanical linkage, boost pressure, or the control strategy of the ECM/PCM.
The exact wastegate design, solenoid operation, control voltage, vacuum/pressure specifications and diagnostic procedure vary by vehicle. Always use vehicle-specific service information before replacing components.
Common Causes of P0244
- Faulty turbocharger wastegate solenoid A.
- Sticking or restricted wastegate actuator.
- Damaged or disconnected vacuum hose.
- Boost-control hose leak.
- Blocked vacuum or pressure line.
- Damaged wastegate linkage.
- Wastegate actuator problem.
- Open or shorted solenoid wiring.
- Corroded or loose electrical connector.
- Poor electrical connection.
- Incorrect solenoid power supply.
- Short to ground or voltage in the control circuit.
- Turbocharger mechanical problem.
- Boost pressure outside the expected range.
- ECM/PCM control-circuit fault.
Symptoms of P0244
- Check Engine Light illuminated.
- Reduced engine power.
- Turbocharger boost may be too low or too high.
- Slow acceleration.
- Reduced turbocharger performance.
- Engine may enter limp or reduced-power mode.
- Unusual turbocharger or boost-control behavior.
- Possible poor fuel economy.
- Additional turbocharger or boost-related codes may be stored.
Is P0244 Serious?
P0244 should be diagnosed promptly.
The severity depends on the actual cause. A simple solenoid or hose problem may not immediately damage the engine, while uncontrolled boost, a malfunctioning wastegate, or a turbocharger mechanical problem can create excessive engine or turbocharger stress.
If the vehicle experiences severe power loss, abnormal turbocharger noise, excessive smoke, extreme boost symptoms, or other serious engine warnings, avoid continued driving until the problem is diagnosed.
Can I Drive With P0244?
Limited driving may be possible if the engine is operating normally and there are no severe symptoms. However, the vehicle may have reduced power or enter limp mode.
Continued driving should be avoided if there are signs of excessive boost, severe power loss, unusual turbocharger noise, heavy smoke, overheating, or other major engine problems.
Turbocharger Wastegate Solenoid A Location
The wastegate solenoid A is normally located in the turbocharger boost-control system. Depending on the vehicle, it may be mounted near the turbocharger, engine, intake system, firewall, or another location connected to the boost-control plumbing.
The solenoid may be connected to vacuum lines, pressure lines, the wastegate actuator and the intake or turbocharger system.
The exact location varies considerably between manufacturers and engine designs. Always use the vehicle-specific service information to identify the correct solenoid.
Component Responsible for P0244
The component most directly associated with P0244 is the Turbocharger Wastegate Solenoid A, but the solenoid should not automatically be replaced simply because the code is stored.
The ECM/PCM may command the solenoid to regulate the wastegate actuator. If the electrical signal, pneumatic control, actuator movement or resulting boost pressure does not behave as expected, P0244 may be triggered.
How to Fix P0244
1. Inspect the Wastegate Solenoid
Inspect the wastegate solenoid for physical damage, contamination, corrosion, loose connections and signs of overheating.
2. Inspect Vacuum and Boost Hoses
Check all hoses connected to the wastegate control system. Look for cracks, disconnected lines, restrictions, collapsed hoses and incorrect routing.
3. Check the Electrical Connector
Inspect the solenoid connector and terminals for corrosion, bent pins, loose terminals, water intrusion and damaged wiring.
4. Test Power and Ground
Verify the solenoid's power supply and electrical ground/control circuit according to the vehicle wiring diagram.
5. Test the Wastegate Actuator
Where applicable, test whether the actuator moves correctly when the specified vacuum or pressure is applied. The actuator should respond according to the manufacturer's specifications.
6. Check Wastegate Movement
Inspect the wastegate linkage and mechanism for sticking, binding or mechanical damage.
7. Verify Boost Pressure
Compare actual boost behavior with the commanded or expected boost value where suitable scan-tool data is available.
8. Test the Solenoid
Test solenoid resistance, activation and control according to the manufacturer's diagnostic procedure. Do not apply a universal resistance specification to every wastegate solenoid.
9. Verify ECM/PCM Control
If the solenoid, hoses, actuator, wiring and mechanical components are confirmed to be correct, inspect the ECM/PCM control circuit according to manufacturer-specific procedures.

Turbocharger Boost Control
The exact control strategy can vary. Some turbocharger systems use vacuum-operated actuators, while others use electronically controlled actuators or different boost-control arrangements.
P0244 OBD Live Data
Depending on the vehicle and scan tool, useful diagnostic information may include:
- Commanded boost pressure.
- Actual or measured boost pressure.
- Wastegate command or duty cycle.
- Turbocharger pressure.
- Engine RPM.
- Engine load.
- Throttle position.
- MAP sensor reading.
- Intake air temperature.
- Accelerator pedal position.
Comparing commanded and actual boost behavior can help determine whether the problem is electrical, pneumatic, mechanical or related to boost measurement.
P0244 Electrical Testing
A digital multimeter can be useful when an electrical problem is suspected.
- Identify the correct solenoid terminals.
- Verify power supply.
- Check the control circuit.
- Check for open circuits.
- Check for unwanted shorts.
- Inspect connector terminal tension.
- Measure solenoid resistance where specified.
- Perform voltage-drop testing where appropriate.
The correct test values depend on the vehicle and solenoid design. Always compare measurements with the manufacturer's specifications.
P0244 Diagnostic Procedure
1. Scan for All Codes
Use an OBD-II scanner to confirm P0244 and record all stored, pending and manufacturer-specific codes.
Additional boost, MAP, turbocharger, electrical or engine-management codes may provide important clues.
2. Record Freeze Frame Data
If available, record engine RPM, load, throttle position, vehicle speed, MAP pressure and other relevant information from the moment the code was stored.
3. Perform a Visual Inspection
Inspect the solenoid, wiring, connectors, vacuum hoses, pressure hoses, actuator and wastegate linkage.
4. Compare Commanded and Actual Boost
Use available scan-tool data to determine whether actual boost follows the requested boost level.
5. Test the Solenoid Circuit
Verify power, control signal, continuity and resistance according to the manufacturer's procedure.
6. Test the Actuator and Wastegate
Check actuator movement and wastegate operation. A sticking mechanical mechanism can produce symptoms similar to an electrical solenoid failure.
7. Check for Boost or Vacuum Leaks
Inspect the complete boost-control system for leaks, disconnected hoses, damaged pipes and incorrect routing.
8. Verify the Repair
After repairing the confirmed cause, clear the code and perform an appropriate test drive while monitoring boost-control data. Confirm that P0244 does not return.

These codes are related to turbocharger or wastegate control, but they do not necessarily indicate the same fault. The exact diagnostic meaning should always be verified for the vehicle being tested.
Common Repair Mistakes
Replacing the Turbocharger Immediately
P0244 does not automatically prove that the turbocharger has failed. The wastegate solenoid, hoses, wiring and actuator should be tested first.
Replacing the Solenoid Without Testing the Circuit
A wiring problem or poor connector can create symptoms that appear to be a failed solenoid.
Ignoring Vacuum or Boost Hoses
A cracked, disconnected or restricted hose can prevent the wastegate actuator from responding correctly.
Assuming High Boost Is Always a Turbocharger Failure
Incorrect wastegate control can cause abnormal boost behavior even when the turbocharger itself is mechanically serviceable.
Using Generic Electrical Specifications
Solenoid resistance and control strategies vary. Always use the specification for the exact vehicle.
Replacing the ECM/PCM Too Early
The ECM/PCM should only be considered after the solenoid, wiring, connectors, actuator and mechanical system have been properly tested.
P0244 Repair Cost
Approximately $50–$150+.
Approximately $30–$150+.
Approximately $80–$300+.
Approximately $50–$250+.
Can range from several hundred dollars to substantially more depending on the vehicle and required parts.
These are general estimates only. Actual costs depend on vehicle make, model, engine, parts prices, labor rates, accessibility and the confirmed cause of P0244.
Vehicle-Specific P0244 Diagnosis
P0244 is a generic OBD-II code, but the actual wastegate control system can vary significantly between manufacturers and engines.
Turbocharger actuator type, solenoid wiring, vacuum routing, boost-control strategy and diagnostic specifications should therefore be verified using manufacturer-specific service information.
Frequently Asked Questions
What does P0244 mean?
P0244 means Turbocharger Wastegate Solenoid A Range/Performance. The ECM/PCM has detected that the wastegate solenoid control system is not operating within its expected range or performance characteristics.
Does P0244 mean the turbocharger is bad?
No. P0244 can be caused by the wastegate solenoid, wiring, connector, vacuum or boost hoses, actuator, wastegate mechanism or another boost-control problem.
Can a vacuum leak cause P0244?
Yes. On systems that use vacuum-operated wastegate control, a leaking, disconnected or restricted hose can prevent the actuator from responding correctly.
