What Does the P00AF Code Mean?

The Variable Geometry Turbocharger (VGT) is electronically activated by the Electronic Turbo actuator. The Electronic Turbo actuator is a smart device and receives information from the Engine Control Module (ECM). The Electronic Turbo actuator performs its own diagnostics and reports failures back to the ECM. The ECM then decodes the error message and converts it to a fault code. This fault code is logged when the Electronic Turbo actuator detected an internal error within the Electronic Turbo actuator. The Electronic Turbo actuator will stop controlling the turbocharger when this fault code is active. The ECM lights the MIL lamp after the diagnostic runs and fails in two consecutive drive cycles. The ECM turns off the MIL lamp after the diagnostic runs and passes in 4 consecutive drive cycles
