中文
含义
NTC温度传感器检测到开路，电阻值异常偏大或无穷大。
常见原因
- NTC传感器内部断裂或老化开路
- 传感器连接插头松动脱落或接触不良
- 传感器线束断路
- 主控板NTC采样电路故障
自助排查
- 断开电源找到NTC传感器位置
- 拔下传感器插头用万用表测量电阻若无穷大则传感器内部断路
- 检查插头端子是否氧化松动线束是否有断裂
- 若传感器阻值正常则问题可能出在主控板需联系售后
English
Meaning
The NTC temperature sensor has been detected as open-circuit; its resistance is abnormally high or infinite.
Common Causes
- Internal breakage or aging open circuit in NTC sensor
- Sensor connector loose disconnected or poor contact
- Broken wire in sensor harness
- Main control board NTC sampling circuit fault
Self-Check Steps
- Disconnect power and locate NTC sensor
- Unplug sensor measure resistance infinite reading = open-circuit sensor
- Check connector terminals for oxidation or looseness
- If sensor resistance is normal main control board may be at fault
