P0244
Turbocharger/Supercharger Wastegate Actuator A Range/Performance
Turbo / boost control
Generic OBD-II
High
What it means
P0244 means the "A" wastegate actuator isn't controlling boost within the expected range — the ECM commands a boost level and the wastegate doesn't respond correctly. That can let the turbo overboost or fall short, and the ECM usually limits power to protect the engine. Most often it's a sticking wastegate, a leaking boost-control hose, or a failing solenoid rather than the turbo itself.
High
Can I keep driving? Driveable but risky under load — the wastegate isn't regulating boost as expected, which can cause overboost or underboost and often a protective limp mode.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power or limp mode
- Boost that surges, spikes, or falls short (over/underboost)
- Poor fuel economy
Common causes
Most likely first
- Sticking or failed wastegate solenoid or actuatorLikely
- Leaking, kinked, or disconnected boost-control vacuum/pressure hoseCommon
- Carbon-seized or mechanically stuck wastegateCommon
- Wiring or connector fault at the wastegate solenoidLess often
- Faulty ECM (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame and boost data to see whether it's over- or underboosting.
- Inspect the wastegate actuator and all boost-control hoses for leaks, kinks, or disconnection.
- Command the wastegate solenoid with a scan tool and confirm the actuator moves freely.
- Check the solenoid wiring and connector for damage.
- Replace the wastegate solenoid or actuator if it sticks or fails to hold. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0244?+
Drive gently and briefly only. Overboost from a stuck wastegate can damage the turbo or engine, so avoid hard acceleration until it's fixed.
Can I just clear P0244?+
It returns as soon as the wastegate misses its boost target again. The actuator, hose, or solenoid must be repaired first.
