Q: What does code P0CAE mean?

Hybrid/EV Battery Temperature Sensor N Range/Performance. P0CAE indicates that the hybrid or electric vehicle battery pack's temperature sensor 'N' is reporting a signal that is outside the expected range or is not performing as designed. The battery energy control module compares this sensor's reading against other temperature sensors and expected values, and it sets this code when the signal is implausible, intermittent, or stuck within a range that does not match reality.
