escort temp sensor problems (HELP)

blackgti · 23-04-2009, 02:39 PM

hi there all i've got a 97 escort gti 1.8 the temp sensor for the temp display is faulty it won't work i've replaced sensor several times now each time the sensor works for a few days then it starts playing up to start with the temp gauge goes all the way to the top and the battery light comes on but if you rev the engine it drops back to normal and the battery light goes out it does this for a few days then packs up alltogether again any advice appriciated

I would start by cleaning all the earths coming from engine/battery, though this is an odd problem, I'm thinking maybe your alternator is spiking.
It's a pitty you can't measure the voltage when this happens.

Do you think it would help to put a new alternator on as well as clean the earths cheers

I wouldn't until 100% positive that the present one is faulty, a dodgy connection is more likely, and cheaper, in any case just a new regulator/rectifier can be fitted to yours, or even recon exchange for less than around £50.

Hi blackgti
did you sort the problem?

as i would like to know as mine has started doing it
no temp at all then all of a sudden it goes into the red and after a bit it settles down to opperating normally
also the battery light comes on

any help would be great

blackgti · 31-01-2010, 06:07 PM

hi cybercypher i tried everything in the end it turned out to be some wiring on the main loom going into the fuse box that was at fault it had been rubbing and worn through did my head in took it to garage to sort in the end good luck with yours mate

Check earths itself, I would think it could be sorted if not with a new regulator and not need a whole new alternator. Check battery voltage with car running and see if it's above what it should be.

well al being well im having a alarm fitted this week by an auto electrian so while he is there ill get him to look into it, as he'll proberly know where to look for the fault
its driving me nuts

i do think it is an electrical fault cos the engine temp goes to red and the battery light stay on when you start the engine, when you rev it the battery light goes off and temp guage goes down.
also the light of the clock is intermitant as well.
we'll wait and see what he says
