Temperature gauge rapidly changing.

[dmallett]

Basically my ph1 gets up to temperature really quick, then it will go between mid way and the top (no stop lights ever come on).
It will do this randomly, at any point it will randomly rise and drop. No patterns in when it happens.

Anyone any ideas?



The car has a new water pump, a new thermostat, a working fan and a new temperature gauge & has had the coolant flushed through & rebled correctly.

Strange. I was going to say it would be the thermostat, but that's new.

When mine did this it was the temperature sensor at fault, sounds like the only part of the system that hasn't been changed!

 

[Bluebeard]

CTS.

CTS.

Ive changed this, presuming you both mean the sensor on the the cross over bit for the heater matrix? I wrote temperature gauge rather than then temp sensor

 

[Bluebeard]

Oh. I'm out of ideas then! Lol

I think they mean the temp sensor under the air filter housing ? I might be wrong though . I think it's quite common for them to have a dodgy wiring / connection . I had this on my 182 when it was brand new , turns out it was just a dodgy connection , i gave it a good wiggle and problem went away . My temp guage would randomly shoot up and down like it had gone mad.

Time to burn it.

Aye thats the one we mean, I have sprayed contact cleaned on the plug, might get a little screw driver in there and try clean it up. Could be that making it so random.

Someone did suggest clocks,

Want me to pop up one evening and we'll have a play with the wiring/Clip?

 

[Munson]

When this happened to my 182 it was the CTS wiring. I think the sender is a misdiagnosis in most cases, and the problem just goes away because the wiring is disturbed when it is replaced.

I take it it was doing this before you changed everything?

 

[Dannyeff]

Mines is doing the same did u bleed the coolant properly? I had this problem in the puma I had before

If you wouldnt mind? need to program that key too! Ill cover you fuel money, which will be about 10p

Yes it was, it started doing it a few months back.

Spot on! Ill try have a look at it before then too and see

 

[Dannyeff]

Any luck with this

 

[dmallett]

Not yet, will hopefully have worked it out by tomorrow evening though

 

[dmallett]

Clocks changed, still not working right

Hi mate. I also had this problem on my ph1 and believe it or not i changed the earth strap that goes from the box to the front panel (behind passenger headlight) and this sorted it. Never once done it again.

Cheers bud! I got check/clean the earth points up at some point as a double measure.

I dont want to get ahead of myself but the past 4 times I drove the car it didnt read hot, im 100% its an electrical issues though.

 

[Sydor]

Hope it works. The symptoms were the exact same

 

[dmallett]

After cleaning out the big white plug in the fuse box and covering it in contact cleaner the issue seems to have stopped.

It was that easy lol
