Where is the heat sensor located in a Nissan 200sx?

In a Nissan 200SX, the heat sensor, often referred to as the coolant temperature sensor, is typically located near the thermostat housing on the engine block. It monitors the temperature of the engine coolant to provide data to the engine control unit (ECU) for optimal performance. In some models, it may also be found near the cylinder head. Always refer to the vehicle's service manual for the exact location specific to your model year.
