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.
