What should I do if my temperature gauge keeps going cold?
In some cases, you can replace the temperature gauge or repair any bad solderings if you find any. In other clusters, you might have to replace the instrument cluster. You can often leave your instrument cluster to an expert to repair the soldering if you do not know how to yourself.
What causes a car temperature gauge to stay on low?
What could cause the temperature gauge to stay on low? The most common causes of why the temperature gauge stays on cold are faulty coolant temp sensor, faulty temperature gauge, broken wires, bad thermostat , and air pockets in the cooling system.
Is it normal for the temp.gauge to go red hot?
Yes, coolant level is fine! The temp. gauge goes to red hot or pinned as soon as I start the car cold. And…after approx. 15 min. driving locally, the engine doesn’t seem to be overheated. so I’m assuming that the thermostat is working fine. I’m just afraid to drive it longer or farther when the temp. gauge says red hot.
How does the temperature gauge on a Honda work?
This sends a signal directly to the dashboard gauge. There is another coolant temperature sensor close by which sends a signal to the ECU to help in engine management. You shouldn’t get confused between the two as the one you want only has one wire and the other has two.

What should the temperature gauge be on a hot engine?
With a hot engine it should measure 30-50 Ohms. If you measure around this value (or definitely not near 140 Ohms) with a cold engine then the unit is faulty and needs to be replaced. A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge.
