Ford Escort 1999 ZX2 Temperature needle not working Sign In

Engine size: 2.0
Mileage: 130k miles

When I start up the car and the engine gets hot like normal, the needle stays in one place and doesn't change at all. How can I fix this?

Do you have access to a scan tool that shows live data? Need to watch the ect sensor and see what its doing. Engine light on? Codes?

tiennu: What is this doing more exactly? Temp gauge just starts off as reading cold and just reaches a "normal" spot on dash gauge and stays there till cooled off or what?


Info for this was a messed up and I don't believe it. Said it's basically and on/off switch that can do multiple functions gauge included and don't buy that.


Get any codes as GC suggested. I plain do not believe ONE switch controls THREE functions and lousy info sheet said it was the same for 29 different models of vehicles including Mazda and a Nissan? Yes both makers are/were associated with Ford here and there.


* Does gauge on dash move at all?
* Do fan(s) come on for radiator?
* Does this engine run properly both cold and warmed up?

The needle stays at cold from the start. Once I turn the engine on, it stays at cold and does not move at all. How can I get codes and a scan tool?

How is the coolant level?

The gauge on this one uses a seperate sensor(sender) than the one used by the engine computer.

To test the gauge and wiring simply unplug the sender and ground the wire. With the key on the gauge should go full hot. If it does and you have plenty of coolant in the system, the sender is bad.

If the gauge doesn't move then you have a problem in the wiring, the gauge, or cluster traces.

Do you have a sedan, coupe, or wagon?

The sender is located in the thermostat housing on the left side of the engine right below where the radiator hose connects. It isn't uncommon for those plastic housing to leak, so don't be surprised if you need to replace it.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

The look up showed two switches with two wires, one with just one wire? All were relatively inexpensive. Yes, as DS said the plug in could be an issue + was some GM ones came with the pig-tail over it.


Test said put it in hot water on a stove with a thermometer so I called it quits looking up parts as that can't be the way it works for the gauge itself.


So far the gauge not moving at all isn't very promising to me for the gauge needle itself. If you get there and think it's just stuck sometimes you have a wild arse chance to just nudge a stuck one if only just stuck going thru the plastic dash where a mechanical trip odometer knob goes thru -- AYOR. IF, IF so the wire used for hobbies I'll call florist's wire is just right for that. May not say but about .5mm wire,
