P00AF: Turbocharger/Supercharger Boost Control "A" Module Performance
2 vehicles · 1 makes · $50-$1,600 repair
Most Reported On
P00AF is an OBD-II diagnostic trouble code meaning “Turbocharger/Supercharger Boost Control "A" Module Performance.” The PCM uses a boost control module/solenoid ('A') to command the turbocharger or supercharger to the requested boost level. This code sets when the actual boost response does not match the commanded value, indicating the boost control 'A' module or its mechanical linkage is not performing correctly. This code is most commonly reported on 2015-2024 Ford Edge (SE, SEL, Titanium), and 2011-2025 Ford F-150, with repair costs ranging from $50 to $1,600.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
