Detection Condition

WARNING: This page is about a different car, the 2002 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.

DTC P0703 indicates PCM did not receive a BPP input.

DTC P1703 indicates BPP signal was high (KOEO) or BPP signal did not cycle high and low (KOER).

Brake Pedal Position (BPP) switch is used by PCM to disengage transaxle Torque Converter Clutch (TCC) and an input to idle speed control for idle quality. BPP is hard wired to PCM and supplies B+ when vehicle brake pedal is applied.
