Useful checks before replacing parts
- Measure sensor B signal, reference supply, ground, reported temperature, freeze-frame data, and related low-input battery temperature codes.
- Inspect for short-to-ground faults, low reference voltage, connector corrosion, water intrusion, damaged wiring, and sensor resistance outside specification.
- Compare signal behavior with nearby battery temperature sensors to determine whether the low reading is real or electrical.
