ECT - Engine Coolant Temperature Sensor

The engine coolant temperature (ECT) sensor (Figure 27) is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signals to the PCM corresponding to temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.
Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage. The ECT sensor is similar in construction to the IAT sensor.

Change ECTsensor on a 2001 f150 5.4L triton


You have 2 seperate engine temp sensors....
1) coolant temperature sensor, which is located next to the water outlet on top of the engien where the upper radiator hose connects. This coolant temp signal is used by the powertrain control module to control such things as fuel mixture, transmission shift points, and cooling fan operation when the engine is hot. If this sensor has failed in such a way that the PCM thinks that the engine is cold, it should also be running very rich (black smoke from the tail pipe, rough idle, very poor fuel economy).
2)Cylinder Head Temperature sensor..You probably cannot see this one, as it is located on the head underneath the intake manifold. You have to Remove the intake manifold to get to this part...Sometimes you can get by just changing the thermostat ...If it is faulty it will show as a sensor..
Anywho they usually twist out ond in..Always make sure you diconnect the battery while working with electronics....
If it is giving a P0125 code this is usually caused by a thermostat that is worn out..

What controls the temperature gauge on a 1990 ford f150 5.0 engine and where is it located


The temp gauge on the dash displays the information transmitted by the coolant temperature sensor. This sensor is located - on the engine - by the water neck. The water neck is where the top radiator hose comes across and connects to the radiator. This sensor can look like the one here:

What controls the temperature gauge on a 1990ford


ECT sensor controls the computer, engine coolant temperature sender controls the gauge. 5.0? 5.8? 4.9? Then I can tell you where it is.

Replacing coolant temperature sensor on 5.4L, where is it located?


its not a true coolant temp sensor. you are looking for cylinder head temp sensor. it is located on the driver's side head, at the front, on the inboard side of the head.

REMOVAL AND INSTALLATION Engine Coolant Temperature (ECT) Sensor — 4.6L and 5.4L Removal and Installation
  1. Remove the engine coolant temperature (ECT) sensor.
    1. Disconnect the electrical connector.
    1. Remove the ECT sensor.

  • sends the PCM a signal indicating engine temperature.
  • resistance decreases as coolant temperature increases.
The ECT measures the temperature of the engine coolant. The sensor is threaded into an engine coolant passage.

ATS(Air temp sensor) CTS( Coolant temp sensor)


I have a 351 but they are common sensors and should be located same places. ATC is on the side or bottom of the air intake filter box. The CTS should be located on the goose-neck where your Thermostat is housed; this is comming off the intake mannafold and into the radiator.
