What happens if your thermostat sensor is bad?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. This will cause the computer to think the engine is cold, even when it is not, and as a result will use more fuel than necessary.
How do I know if my thermostat sensor is bad?
