Q: What does code P05E6 mean?

Park Brake Sensor/Switch Circuit Range/Performance. P05E6 indicates that the powertrain control module (PCM) has detected an out-of-range or erratic signal from the park brake sensor or switch circuit, meaning the voltage or performance does not match expected values for the current park brake state. The PCM compares the park brake switch input against other inputs such as vehicle speed and transmission range to determine if the circuit is functioning correctly.
