    Sensor is for a 2000 Expedition 5.4 Trident, is there another sensor that regular gas flow, if so send picture and part/s #, suv is jerking above 45 to 50 MPH

  • abesherrod Oct 07, 2009

    removed the intake manifold and still could find the coolant temperature sensor that regulates the gas flow. The computer is reading the sensor defective. Is there another location that I can look for the sensor. 2000 Ford Expedition, 5.4 . SUV is jerking when speed gets above 50 MPH. Send picture/diagram if you have.

    Still can not find the coolant temperature sensor that regulates the fuel on 2000 Ford Expedtion 5.4. it is not on the right side next to the thermostat housing and altanator and is not under the intake manifold. Where else could it be ?

Hi,

Coolant Temperature Sensor

This sensor monitors the temperature of the engine and sends that information to the engine control computer to regulate the amount of fuel needed. More fuel is needed if the engine is cold; less if it's hot. If the temperature is extreme, the signal will be sent to the temperature gauge as a visual indicator of overheating and imminent danger..


Inspect

Inspect the sensor's wires and connections. ECT (engine coolant temperature) sensor problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the sensor itself.
If the wires or connections are bad, replace them. If you think the sensor is defective, it should be tested.

Replacement

Because ECT (engine coolant temperature) sensor procedures vary depending upon their location, first locate the part. You may need to partially drain the engine coolant to prevent coolant spillage.

  • Disconnect the negative battery cable.
  • Unplug the ECT.
  • Then, unscrew it.
  • Reverse the removal procedures to install the new part.
  • Connect the negative battery cable to the battery.
Location -

Engine Coolant Temperature (ECT) Sensor
4.6L Engine Coolant Temperature (ECT) Sensor is on left side of the alternator according to the pictures on my Chilton's book.
5.4L Engine Coolant Temperature (ECT) Sensor is on right side between the alternator and the top radiator hose / thermostat housing according to the pictures on my Chilton's book.

The diagram for the same is :-

Let me know, if need further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Cylinder Head Temperature Sensor The cylinder head temperature (CHT) sensor (Figure 26) is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as temperature increases, and increases as 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 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 cylinder head temperature (CHT) sensor is installed in the aluminum cylinder head and measures the metal temperature. The CHT sensor can provide complete engine temperature information and can be used to infer coolant temperature. If the CHT sensor conveys an overheating condition to the PCM, the PCM would then initiate a fail-safe cooling strategy based on information from the CHT sensor. A cooling system failure such as low coolant or coolant loss could cause an overheating condition. As a result, damage to major engine components could occur. Using both the CHT sensor and fail-safe cooling strategy, the PCM prevents damage by allowing air cooling of the engine and limp home capability. For additional information, refer to Powertrain Control Software for Fail-Safe Cooling Strategy details.





Figure 26: Cylinder Head Temperature (CHT) Sensor Differential Pressure Feedback EGR Sensor For information on the differential pressure feedback EGR sensor, refer to the description of the Exhaust Gas Recirculation Systems.
Engine Coolant Temperature 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.

Coolant temperature sensor location on 97 ford expedition


I believe they are located in the intake manifold somewhere. Make sure the one that tells the computer the coolant temp is ACTUALLY giving out the correct temperature. I had a bad one one time in a 1993 Ford F-150, 5.8L....... no check engine light came on but hard to start. The bad sensor was telling the computer it was 32 degrees F when it was almost 80 degrees outside.!!
Garbage in=Garbage out.

Here is a video link from Youtube. There are 2 sensors, 1 for the guage and the other tells the on-board computer how hot/cold the coolant is. The one for the guage has 1-wire and the other one has 2 wires.
Hope this helps, ask more if you need to. What kind of problem are you having? No heat inside? Guage needle not getting into the normal area?

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.


12_5_2011_5_38_05_pm.jpg

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.

Where is the throttle position sensor located on a 2000 ford expedition xlt


The TPS is located on the side of the throttle body closest to the front of the vehicle. There are two electrical units attached to the throttle body the other being the IAC or idle air control. The IAC is usually a cylindrical object about 3" long and 1 1/4" in diameter.
