Hi all,
My 2000 2.0l has just developed a peculiar temp gauge fault.
The car warms up as usual, the needle rises to vertical (as it always has) then starts to drop back towards cold, then rises towards normal again and then fluctuates between just off cold and normal as you drive.
Now I'm pretty sure that this is related to some temp sensor somewhere and nothing to do with the cooling system. I've done a gauge check (holding down the trip reset whilst starting) all show full sweep, not DTC errors to report, and the digital temp readout reflects the erratic behavior of the analogue gauge fluctuating between 60-85 degrees over a couple of minutes.
Another downside to this is that the petrol consumption seems to be suffering dropping about 20 miles on a tank full over the last couple of fill up's. I can only assume that the engine management system is using the reported temperature and adjusting the mixture accordingly?
Any thought anybody?
