1. Check if the sensor resistance is normal, otherwise replace it.
2. Check if the sensor cable is short-circuited or open-circuited, and if the fiss is well adjusted, if a connection to the board has been unstuck, and repair accordingly.
3. When steps 1 and 2 are normal, then the components or IC are damaged, and the electronic board needs replacing.
