Code P1B12 Saturn Description

The Electronic Brake Control Module (EBCM) monitors the brake pedal position sensor in order to provide emission related brake pedal position information to the Engine Control Module (ECM). The EBCM sends the information, via the serial data circuit, to the ECM in a continuously repeating series of 16 rolling counts, with each count assigned a value. When the ECM determines that too many of the counts have an incorrect value, the ECM sets DTC P1B12.
