The temperature sensor's placement depends on its intended application. In HVAC systems, it is typically installed in air ducts or near vents to monitor air temperature. In industrial settings, it may be placed on equipment or in fluid systems to measure process temperatures. For household appliances, like refrigerators or ovens, the sensor is located within the unit to ensure accurate temperature control.
There is a sensor right where the upper radiator hose goes into the engine.
A NTC thermistor is a temperature sensor that has a "negative temperature coefficient". That means as temperature goes up, the resistance of the device goes down over it's operating range.
The temperature sender for the coolant is located in the water outlet. The upper radiator hose goes to the water outlet. The sensor with 2 wires goes to the gauge and the sensor with 3 wires goes to the computer.
Where the top hose of the radiator goes is called the water outlet pipe. The sensor for the coolant temperature is in this pipe. There are 2 sensors. One goes to the gauge on the dash and the other goes to the computer. Not sure which is which, but if you unplug the one that goes to your dash the temperature gauge will peg.
1. Water temperature sensor Intake air temperature sensor cylinder head temperature sensor exhaus temperature sensor and catalytic sensor
The Ford Zx2, all years do not have an air intake temperature sensor. The MAF sensor/mass air flow sensor detects both the air temperature, and the air volume being inducted. The MAF sensor is located in the air cleaner box near where the hose goes toward the engine, and will have a bundle of wires going into it.
The external air temperature sensor on a Chrysler PT Cruiser is located in the front of the motor. It is in the air intake tube that goes from the air cleaner to the motor.
It is just below the housing that the radiator cap goes on.
the coolant temperature sensor is faulty. It will need to be replaced
Because if the sensor temperature part is defective it will automatically turn on the fan all the time. If you unplug the temperature sensor in the cooling system the fan will automatically come on. You need to replace the temperature sensor that goes to the Powertrain Control Module (computer).
At the back of the engine on the coolant outlet that goes to the heater hoses on the firewall.
follow the top radiator hose away from radiator to engine,you will see the hose does not go directly to engine but goes to a aluminum box with 2 sensors connected to it. the one wired sensor is a temperature sensor and the 2 wired sensor is the other temperature sensor. one gives temp to dash panel,while the other sends signal to computer .
