in this episode we will be replacing the coolant temperature sensor which is a nice quick job to do and give you peace of mind that the engine temp is correct. An engine coolant temperature sensor is essential for the optimal performance of your car. The engine coolant temperature sensor’s job is to measure the coolant temperature for the engine control module.
A faulty coolant temp sensor can send a false signal to the onboard computer, resulting in an incorrect air-fuel mixture. For example, a faulty sensor can send a signal indicating the engine is cold when it is not, and more fuel will heat the engine quickly or vice versa
