P0BC3 Hybrid/EV Battery Temperature Sensor E Circuit Range/Performance
The ECM detects a circuit range/performance fault on the hybrid/ev battery temperature sensor e circuit. Reading cannot be used reliably for control.
Is it safe to drive with P0BC3?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelySensor characteristic drifted
- PossibleSensor mounting displaced
- Less likelySensor element aged beyond calibration window
Symptoms
