What is the reason for the Wuling Hongguang water temperature gauge not displaying?
2 Answers
Wuling Hongguang water temperature gauge not displaying is caused by a faulty water temperature sensor or instrument wiring harness issue. The water temperature gauge displays the coolant temperature, helping the owner understand the vehicle's condition. When the car's water temperature is too high, the owner should stop and wait for the temperature to drop to normal levels before continuing to drive. Below are the reasons for the water temperature gauge not moving: 1. The power line of the water temperature gauge is broken; the heating coil of the water temperature gauge is burnt out. 2. The heating coil of the water temperature sensor is burnt out or the contact points are poor. 3. Poor connection or breakage of the water temperature sensor wire. 4. Damage to the voltage stabilizer that supplies stable power to the water temperature gauge circuit.
Last time I drove a Wuling Hongguang, I also encountered the issue of the temperature gauge not displaying. Later, I found out it was because the temperature sensor plug was loose. There are usually several common reasons for the temperature gauge not working in this car: the most common is a faulty temperature sensor, which is installed near the engine cylinder head; it could also be due to a burnt-out dashboard circuit board, especially in older cars; a blown fuse is another frequent cause, located in the fuse box under the steering wheel. It's recommended to first open the hood and check if the sensor plug is loose, then inspect the fuse. Driving without being able to see the temperature is dangerous, as you wouldn't know if the engine overheats. A mechanic told me that this issue is quite common in Wuling vehicles, and replacing the sensor with an original part only costs a few dozen yuan.
