Temp Gauge off & on
« on: 02 August 2007, 16:10:47 »
Hi Guys

Hope someome can advise me.

My temperature gauge is working fine one day then not at all next day. It tends to be when there is a warm day and I check the gauge for any overheating and its showing zero. Then the following day okay.

The car runs fine and I have cleaned the spade connection on what I think is the temperature sensor. But it keeps happening. :(

Any ideas? is it the sensor or the gauge? :y

Not aware of any inherent issues with this fault...   sounds to me like a faulty temp sender, going HR in hot conditions...  If you remove the plug and bridge the connections, guage should read high.. this will prove the guage, OK... if not flty sender....

 :y When you say bridge the connections. What I think is the sensor only has one spade connection with a single wire to it.

This is on top of the thermostat housing. :-/

Or am I looking at the wrong thing?

I had this problem on my Omega once, in the end the gauge stopped all together. After a lot of fault finding i traced the fault back to the bash board itself. The fault was actually where the dash connects to the loom, it is a push fit. But before you start stripping things down just push the clocks in to make sure the connection is good. This was all that was needed on mine in the end, when i pushed the clocks they moved back about 4 mm or so and bingo the temp gauge has worked ever since ;)

I've a similar problem.  temp guage sometimes sticks.  Easily fixed by a gentle tap on the dash, seems to work ok after that
