The hybrid powertrain control module detects no change in brake pedal position after brake applied.

DTC P057C

• The hybrid powertrain control module detects a short to voltage in the BPP sensor 5V reference circuit.
• The hybrid powertrain control module detects a short to ground or an open/high resistance in the BPP sensor 5V reference circuit.
• The hybrid powertrain control module detects a short to ground or an open/high resistance in the BPP sensor signal circuit.

DTC P057D

• The hybrid powertrain control module detects a short to voltage in the BPP sensor signal circuit.
• The hybrid powertrain control module detects an open/high resistance in the BPP sensor low reference circuit.

DTC P057E 

The hybrid powertrain control module detects the BPP sensor signal is changing faster than possible under normal operating conditions.
