The coolant temperature sensor is an important part of your vehicle's cooling system. It monitors the temperature of the coolant and sends a signal to the engine computer, which adjusts the amount of fuel and air that is sent to the engine. If the coolant temperature sensor fails, it can cause your vehicle to run rich or lean, which can damage the engine.
If you suspect that your coolant temperature sensor is failing, you should take your vehicle to a qualified mechanic for diagnosis and repair.
