COOLANT TEMPERATURE GAUGE CODE

Check Engine Light On – on some modern cars, the engine car computer monitors the engine temperature over time, and will set a stuck open thermostat fault code and turn the Check Engine Light (CEL) on to warn the driver.Low-temperature warning light – Some cars have a warning light which will illuminate if engine temperatures are lower than normal.This is due to non-optimal running temperatures. Increased fuel use – Low engine temperatures will also affect your car’s fuel consumption.Reduced engine performance – A cold engine will struggle to accelerate, stutter and sometimes stall while you are driving.This happens due to faulty sensors or incorrectly installed gauges. Faulty temperature gauge – Sometimes, the temperature gauge can give a low reading, even when the engine temperatures are normal.This can lead to a gradual decrease in engine temperature. Sometimes, the radiator fan can become stuck on due to faulty sensors or internal issues.

Radiator fan issues – The radiator fan reduces coolant temperature, allowing it to continuously cool the engine.An inaccurate or inconsistent reading can lead to the thermostat remaining open and bringing down engine temperature. Faulty temperature sender unit – On some modern engines the temperature sender unit monitors engine temperature and tells the thermostat when to open and close.If the thermostat becomes stuck open, too much coolant will enter the engine, resulting in engine temperatures decreasing. It does this by opening and closing to let coolant into the engine. Thermostat stuck open – The thermostat is used to regulate engine temperature.If the engine temperature gauge on the dashboard reads say 1/3 or less after 5 to 10 minutes then your engines cooling system thermostat could be stuck open, or there could be an issue with the engine temperature gauge, its wiring, or the coolant temperature sensor used for the engine temperature gauge. For example a typical engine should reach about half way on the temperature gauge on the dash after 5 to 10 minutes normal driving. If it stays lower than normal for a prolonged period of time, you should have your cooling system inspected for issues. The temperature of your engine can be monitored via the temperature gauge on your dashboard. If too much coolant flows through your engine, it will fail to reach its ideal operating temperature. It does this by pumping coolant through your engine to reduce its running temperature. Your car’s cooling system is designed to prevent the engine from overheating. Learn more about how the cooling system works > Low engine temperatures are usually caused by a problem in the car’s cooling thermostat or cooling system. Failure to reach this temperature results in decreased engine power and efficiency. In most cars, this temperature is around 90☌. Your car’s engine needs to reach an optimum temperature in order to run correctly. If you’ve ever had to start your car on a cold morning, you will know the effect that cold temperatures have on your engine. A blue light often indicates lower than normal engine temperatures.
