Does a Chrysler pt cruiser have sensor which protects the engine from overheating?

Yes, the Chrysler PT Cruiser has a sensor that protects the engine from overheating. This sensor is called the coolant temperature sensor, and it is located in the engine block. The coolant temperature sensor monitors the temperature of the coolant in the engine, and if it detects that the coolant is too hot, it sends a signal to the engine control unit (ECU). The ECU then takes action to cool down the engine, such as by turning on the cooling fans or reducing the engine speed.
