Why does the Ford Focus temperature gauge not rise?

[LaSophia]

The reasons why the Ford Focus temperature gauge does not rise are: 1. The power line of the temperature gauge is broken. 2. The heating coil of the temperature gauge is burnt out. 3. The heating coil of the temperature gauge sensor is burnt out or the contact is poor. 4. The wiring of the temperature gauge sensor is poor or broken. 5. The voltage regulator supplying stable power to the temperature gauge circuit is damaged. The solutions to fix the temperature gauge not rising are as follows: 1. First, confirm whether the circuit is normal. Turn on the ignition switch and short the two wires—if the temperature gauge moves, the circuit is fine; otherwise, there is a circuit fault. 2. If the circuit is confirmed to be normal as above, connect the thermostat and turn on the ignition switch—if the temperature gauge moves, the thermostat is faulty and needs to be replaced.
