WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The brake fluid pressure sensor is integral to the BPMV/EBCM. The brake fluid pressure sensor is not serviceable. After replacing the BPMV, and the DTC resets as a current code, it may be necessary to perform a brake pressure sensor calibration with the Tech 2 in ABS, special function.
