You can often take your instrument cluster to an expert to repair the soldering if you do not know how to do it yourself.Ī faulty cluster is not a very common problem, though, and they are often pretty expensive and need programming after replacement. In other clusters, you might have to replace the whole instrument cluster. In some cases, you can replace the temperature gauge or repair any bad solderings if you find any. However, most temperature gauges are integrated with the instrument cluster on modern cars. The next problem is a faulty temperature gauge. Check a wiring diagram of your car to measure the wiring correctly. You can also find information about this in your repair manual. However, this requires a bit of electronic car knowledge, and you may have to let your mechanic take a look at it without it. The best way to find broken wiring is to measure the resistance with a multimeter from all the wires’ directions. Check for any broken wires between these components. If you have one sensor for both of them, there could either be a problem with the wires between the sensor and the ECU (most likely) or a wiring problem between the gauge and the ECU. If you have two temperature sensors on your car (one separate for the gauge), you need to check the sensor’s wires to the gauge or ohm measure the sensor from the cluster connector. However, if you decide to replace one of them, and your car has two sensors, you should make sure to replace the sensor going to the temperature gauge. We will talk more about how to diagnose the sensor properly later in the article. You can also find more information on how to test them in a repair manual. If your car model has two coolant temperature sensors, one is used by the temperature gauge, and the other one is used for the engine control module.Įngine temperature sensors are easy to measure with a multimeter, but you need to find the correct values for them. The models with one sensor usually use the same sensor for both the engine control unit’s temperature and the gauge. Some cars have two temperature sensors, while other car models have just one.

Faulty Engine Coolant Temperature SensorĪs we talked about, the most common problem with a faulty engine temperature reading is the coolant temperature sensor itself sending wrong information to the cluster. Here is a more detailed list of the most common reasons why a temperature gauge stays on cold. Let’s go a little bit more into detail about the different causes. In some cases, it can also be a stuck thermostat causing the engine not to heat up properly. It can also be caused by bad wiring between the cluster and the sensor. The most common reason why your car’s temperature gauge stays on cold is a faulty coolant temperature sensor. Conclusion 7 Reasons Why Your Car Temperature Gauge Stays on Cold
