What P0244 means
P means powertrain (engine and transmission). The 0 marks a generic code defined by SAE, so the same number means the same thing across makes. The third character, 2, places it in the fuel and air metering, injector circuits subsystem; the last two digits identify the specific fault.
The wastegate solenoid controls how much exhaust bypasses the turbine and therefore how much boost the turbo makes. The engine computer pulses it and monitors its control circuit.
The letter "A" distinguishes between two or more of the same component on one vehicle. Which physical part is "A" is set by the manufacturer, so confirm it in the service information before replacing anything.
What “Range/Performance” means here
"Range/Performance" means the circuit is electrically intact — the signal sits inside its normal window — but the value does not make sense for the operating conditions. The module cross-checks it against what other inputs predict (a rationality test). That usually points at the turbocharger wastegate solenoid itself or the system it measures, rather than at the wiring.
What you may notice
Symptoms depend on the vehicle and on how the module responds to the fault. Any of these can accompany P0244:
- Loss of power
- Overboost or underboost codes stored alongside
Where to start diagnosing P0244
- Inspect the solenoid connector and its vacuum or pressure hoses.
- Measure solenoid resistance against specification.
- Use an actuator test, where available, to confirm the solenoid responds.
Clear the code only after recording freeze frame data: it shows the engine speed, load and temperature at the moment the fault set, which is often the best clue to reproducing it.
Live data to watch
These standard OBD2 values relate to P0244. Support varies by vehicle; a value your car does not report will simply be missing.
| Value | What to look for |
|---|---|
| Intake manifold absolute pressure (PID 0x0B) | Boost response. |
| Boost pressure control (PID 0x70) | Where supported, commanded duty and boost. |

Codes from the same turbocharger wastegate solenoid family. If several are stored together, the shared part — wiring, a common reference voltage, or the component itself — is the place to start.

Frequently Asked Questions
What does P0244 mean?
P0244 is the generic SAE J2012 code for "Turbocharger/Supercharger Wastegate Solenoid "A" Range/Performance". In plain terms, it means the engine computer has detected a "range/performance" fault on the turbocharger wastegate solenoid.
Can I keep driving with P0244?
Drive gently: boost control is compromised until it is fixed.
What should I check first for P0244?
Inspect the solenoid connector and its vacuum or pressure hoses.
