How to troubleshoot a faulty engine temperature sensor in the Kia Sorento?

I recently noticed that my Kia Sorento's engine temperature gauge is not displaying the correct temperature. How do I troubleshoot and fix this issue?

First, check if the engine temperature sensor is properly connected and if any wires are damaged. You can also use a multimeter to test the sensor's resistance. If the sensor is faulty, replacing it should solve the issue.

Another possible cause could be a malfunctioning thermostat. A bad thermostat can cause the engine temperature to rise or fall rapidly. Have it checked and replaced if necessary.

Make sure to also check the coolant levels in your car. Low coolant levels can cause the engine to overheat. If the levels are low, top-up with the recommended coolant.

If none of the above solutions work, it's best to bring your car to a certified mechanic for a thorough inspection. They will be able to diagnose any other potential issues that could be causing the faulty engine temperature reading.
