Pinpoint Test N: DTC B2734, B2736, B2737, B2738, B2740 Pedal Travel Sensor Fault

Normal Operation
The brake pedal travel sensor sends current to the Anti-Lock Brake System (ABS) module proportional to the brake pedal position.

Reference voltage is supplied by circuit 3010 (TN). Ground is provided through circuit 3011 (BK/OG). The sensor signal is supplied by circuit 3012 (WH).

Possible Causes
^ circuit 3010 (TN) open, short to voltage, or short to ground
^ circuit 3011 (BK/OG) open, short to voltage, or short to ground
^ circuit 3012 (WH) open, short to voltage, or short to ground
^ brake pedal travel sensor
^ ABS module
