P00AF OBD-II: Turbocharger/Supercharger Boost Control "A" Module
P00AF Severity
Should you fix P00AF yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P00AF?
The engine control module (PCM) uses a Boost Control Solenoid to control the turbocharger and provide the requested amount of boost. When the PCM detects an incorrect signal from the Boost Control Solenoid, it will set code P00AF.
