48V Battery Temperature Sensor Circuit Malfunction
2014-2021 Mitsubishi Outlander 2.4L I4
Description
The 48V lithium-ion battery temperature sensor is reporting values outside the expected range.
Symptoms
- 48V system may be limited
- Charging/discharging restricted as precaution
- Inaccurate temperature reading
- Mild hybrid functions intermittent
- 48V battery warning
Common Causes
- Temperature sensor failure
- Sensor wiring open or shorted
- Connector corrosion
- Sensor out of calibration
- Thermal paste degradation on sensor
Diagnostic Steps
- Read 48V battery temperature PID
- Compare to infrared temperature measurement
- Test sensor resistance vs specification
- Inspect sensor connector
- Check wiring for damage
Repair Notes
Replace 48V battery temperature sensor. Ensure proper thermal contact with battery cells.
