What does a faulty temperature sensor do?

While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal. The computer will again miscalculate the signal and cause the engine to heat up instead of cooling it down. When this happens, the car might misfire, or it could lead to engine knocking.
