Full Version: Problem With Temperature Gauge And Warning Light
Ford Owners Club - Ford Forums > Ford Models > Ford Fusion Club
Hi all ! have a 2003 1.4 TD, The temperature gauge moves wildly up and down along with a red temperature light comes on ,had this problem last year and it just stopped !!but is back again,!!this happens for a few days then goes off again, then comes back on again for a day or two !!!! the engine in not over heating so have no idea what the problem is ?? any idea's ??
What you could try is a gauge test.

Put the ignition on then the lights, one click. Now whilst holding down the left indicator press and hold the rest button on the indicator stork. After about 5 seconds the LCD display should say Test at this let go of the reset and indicator.

Cycle through the various tests by pressing once and releasing the reset button.

Hope that helps.

It could be a dodgy thermostat (valve) or possibly the temperature sensor, but the symptoms appear more mechanical than electrical so I would go for the thermostat first.
Does the temp gauge track ok from cold to warm (5 to 10 minutes from a cold start)?
