Code B0226 Description

The B0226 diagnostic trouble code (DTC) indicates that there is a high voltage condition detected in the recirculate position command circuit of the vehicle. This code is typically found in vehicles with automatic climate control systems that allow the driver to control the flow of air within the cabin. The recirculate position command circuit is responsible for regulating the recirculation of air inside the vehicle, which can impact the overall comfort and air quality for the occupants.
