200 Ford Focus 1.6, temperature gauge at full, even on ignition

I have a 2000 Ford Focus 1.6ghia. The temperature gauge is always on the red, so the engine management system thinks the car is over heating and cuts the engine. I've had the cooling sensor replaced and the car worked fine for about 6 weeks. Now it is doing it again. Coolent levels are fine. Any ideas of what I can suggest to the garage when I take it there?

Cheers,

Mark

    The gauge is on the red as soon as the gauge gets power, before the engine has even started.

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

Ford focus 2003 temperature gauge jumps to red


Check the operation of your thermostat.
Check that the radiator is filled with fluid and that there are no bubbles in the system (this should only be as a result of a radiator re-fill).
Check that the radiator fan comes on as the gauge needle moves over half way and into the red.

Ford focus fuel gauge not working


it might be the floater inside the gas tank or the sending unit which sends the info to the ecu and tells you how much gas you have replace that and it should work, sometimes it can be a faulty cluster gauge too

Dash temp guage goes to red on 2000 ford focus dohc zetech


Because you have done so many repairs already I would most likely say that the gauge is defective. I would use a manual temp probe and probe the coolant temp after the car has reached operating temp. Coolant will be between 180- 230 degrees. If coolant temp checks out and you can see coolant moving in radiator and the vehicle does not overheat then you will need either a gauge or a coolant sensor. To locate the sensor it should either be mounted in the thermostat goose neck housing or the intake manifold.

2001 ford focus zx3 temperature gauge goes in the red and the yellow exclimation comes on. But all coolant levels are ok and no leaks and the fans run.


the problem may be the temperature sensor or the gauge itself, it is most likely easier to replace the sensor than the gauge....hope this helps.......cheers

2000 FORD FOCUS IGNITION REPLACEMENT INSTRUCTIONS


Your ignition is what supplys your spark pluggs with electricity in order to creat combustion in your engine. Most older cars have distributers, if you drive a focus with a zetec it will have a coil pack. I have a 2002 Focus SVT that I upgraded the ignition system to a full racing system for around $200. What you need to change is the coil pack, spark pluggs and spark plugg wires. You only have to remove about four bolts on the coil pack and it just pulls out.
