Coolant sensor


The Engine Coolant Temp Sensor (ECT) is located in the engine compartment, on the top rear of the intake manifold

Location of temperature sensor that operates the temperature gauge


Follow the upper rad hose to the thermostat housing. It will be there. There are two, one is the ECT (engine coolant temperature SENSOR) and the other is the temperature SENDING UNIT (input for temp. gauge ONLY). f83e91b9-4b48-476a-8c50-10735b376bf1.png

Location of engine coolant temperature sensor


Automobiles: 2000 Ford Escort ZX2 4-cylinder 2.0L MFI DOHC

NOTE
The "left" side of the engine is the driver's side.

The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").

The ECT sensor is mounted in the following locations (small Ford engines):

1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine

2.0L Zetec Engine

(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.

Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.

To install:

NOTE
Coat the ECT sensor O-ring with clean coolant prior to installation.

(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.

Have a 95 ford ranger 4 cyl need to know where coolant temp switch is located my gauge is inop i found coolant temp sensor for computor need one for the gauge


On the 4 cylinder motor (2.3L,2.5L), the coolant temp sensor can be located
on the left side rear of the engine, below the cylinder head.

A picture of a typical Coolant Temp Sensor (aka ECT) is below:

Be sure to partially drain coolant below the level of the sensor to avoid spillage when removing the old part. Best of luck on your repair!

Where is the temp gage sensor location 2001 merk cougar


Hi there,

The temperature gauge relies on readings from the Engine Coolant Temp (ECT) Sensor.

The ECT sensor is usually located on (or near) the thermostat/coolant housing.

Refer to component No. 8 (2.0L Engine):

wolfman304_70.gif


Refer to component No. 9 (2.5L Engine) locate under bypass tube:

Hope this helps.

Coolant sensor is bad on my 01 Eclipse 2.4 L motor. I need to know where it is on my car and how to change it


Hi there,

Diagnostic codes # P0115 to P0119 all relate to the ECT (Engine Coolant Temp) sensor circuit.

Assuming you have correctly diagnosed a faulty ECT sensor, here are the instructions to locate and test:

* Look for a bolt size sensor with a wire attached - on Mitsubishis, the ECT sensor is usually located either on the Intake Manifold, or close to the Thermostat housing (to measuer coolant temp).

This is what is looks like:

* To test the ECT sensor:

* With the sensor portion immersed in hot water, check resistance as per the table below (convert to degrees F if necessary):

wolfman304_65.gif
* If the resistance is too far out of spec, then replace the sensor.


Cheers,

Hi there. 2002 Petrol Ford Focus Zetec 1,6lt Automatic . Radiator was boiling over and the cooling fan is not engaging. I have checked thermostat, fuses etc and all seems fine. The local garage here in...


I have the U S wiring book. It may be similar to European version. I will look at work and see. Does the cooling fan come on when you turn on the a/c and the compressor clutch? The fan should cycle with the a/c clutch. Also, do you have 12 volts at the motor connection when the car is hot? There should be a big fuse in the box under the hood and probably a relay.
ALso, the ECT, engine coolant temp sensor on the engine should also tell the computer to turn on the fan when the coolant hits a certain temp.

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.
