Details of the p00af OBD Code
P00AF code indicates a turbocharger/supercharger boost control module performance issue.
Code P00AF means that the turbocharger compressor bypass valve control circuit is stuck open.
This code is triggered by the Engine Control Module (ECM) when it detects that the turbocharger compressor bypass valve is not functioning properly.
The turbocharger compressor bypass valve is responsible for controlling the boost pressure in the intake system.
When the control circuit is stuck open, it can lead to a decrease in engine performance and efficiency.
Mechanic’s Tech Notes
Code P00AF relates to a turbocharger/supercharger boost control module performance issue.
To diagnose and fix OBDII code P00AF, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.
This thorough inspection can help identify and resolve issues related to code P00AF.
