如何排查
先做花钱最少、侵入最小的检查——大多数这类码不是零件问题。
- ✓ Check the small grille near the steering column or dash for blockage.

B0160 —— 常见问题
Why does the fan run constantly on full? +
If the ECU believes the cabin is far from target it commands maximum output. A dead sensor is the usual cause.
Can I clean the sensor? +
You can clean the grille, but do not spray cleaners into the sensor itself.
