Symptoms of P0244
- Check-engine light on, sometimes with rough or uneven running.
- Hesitation, surging, or a noticeable change in fuel economy.
- Occasionally hard starting or a smell of unburnt fuel.
Common causes of P0244
- A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
- Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
- Wiring, connector, or fuel-delivery problems that skew the reading.
Useful checks before replacing parts
- Compare wastegate solenoid A command with desired boost, actual boost, actuator position if available, airflow, and engine load.
- Inspect solenoid plumbing, vacuum supply, actuator binding, wiring voltage drop, connector condition, and boost leaks.
- Check whether the problem is underboost, overboost, slow response, sticking hardware, or incorrect pressure sensor feedback.
How serious is P0244, and can you keep driving?
- Urgency
- Moderate
- Safe to drive?
- Usually, for short trips and gentle throttle — but do not leave it.
A mixture or airflow fault rarely strands a car, which is exactly why it gets ignored. The risk is not the drive home, it is the months after. An engine running lean under load runs hotter and is more prone to detonation; one running rich washes oil off the bores and loads the catalytic converter with unburnt fuel. Both damage things that cost far more than the sensor or the leak that started it. Treat it as a fault to fix this month, not this year, and avoid sustained high load until it is fixed.
Clearing P0244, and making it stay gone
Clearing P0244 with a scan tool switches the lamp off; it does not fix anything, and it throws away the freeze-frame snapshot the car saved when the fault set. That snapshot is the most useful diagnostic evidence you have, because it records the load, RPM and temperature at the moment the test failed. Read it before you erase it.
Left alone, the lamp goes out on its own once the monitor that failed runs and passes on three consecutive driving cycles. The code stays in history after that, which is how a workshop can still see it. Disconnecting the battery is not a shortcut — it clears the stored codes and every learned fuel-trim value with them, so the car relearns from scratch and the underlying fault simply sets the code again.
On vehicles from roughly 2010 onward there is also a permanent DTC, which no scan tool can erase at all. It clears only when the monitor genuinely passes. That is deliberate: it stops a code being wiped in the car park outside an emissions test.
What P0244 costs to put right
There is no honest single figure for P0244, and any page that gives you one is guessing. The code names a circuit or a failed monitor, not a part — the same code can be a chafed wire, a connector full of water, or the component itself, and those are three very different bills.
The number worth budgeting for is diagnostic time. An hour of it is almost always cheaper than the second part you buy after the first one does not fix it, and parts fitted on a guess are rarely refundable once installed. If you are getting a quote, ask what the diagnosis found rather than what is being replaced — a fuel / air fault traced to a specific cause is a repair, and a list of parts is a hopeful shopping list.
Questions people ask about P0244
What does P0244 mean?
P0244 points to wastegate solenoid A range/performance. The solenoid circuit may operate but boost response does not match command.
Can I drive with P0244?

What causes P0244?
The usual candidates are a failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor); intake or vacuum leaks, or an exhaust leak near an upstream sensor; wiring, connector, or fuel-delivery problems that skew the reading. The code tells you which test failed, not which of those did it — that is what the checks on this page are for.
Will P0244 clear itself?
Left alone, the lamp goes out on its own once the monitor that failed runs and passes on three consecutive driving cycles. The code stays in history after that, which is how a workshop can still see it. Disconnecting the battery is not a shortcut — it clears the stored codes and every learned fuel-trim value with them, so the car relearns from scratch and the underlying fault simply sets the code again.
Does P0244 mean I need to replace a part?
Do not diagnose range/performance from boost pressure alone; verify solenoid command and actuator response.
How much does it cost to fix P0244?
There is no honest single figure for P0244, and any page that gives you one is guessing. The code names a circuit or a failed monitor, not a part — the same code can be a chafed wire, a connector full of water, or the component itself, and those are three very different bills.
