Temp sensor fault

[Anonymous]

It seems I'm the latest victim of the notorious Temp sensor fault.
It's booked in tomorrow, I dropped it in today, a salesman told me he had the same fault on his gti
and it's nothing to worry about, the car isn't overheating and that his was an easy fix.
I'm not so sure, I've done about 5 miles in it with the fault and I've got some oil custard inside
my oil filler cap, surely not a good thing.

I've read pretty much all the threads I can find on here, and a few elsewhere dating way back to 2010 and couldn't find
a definitive answer, does anyone know if Peugeot have sorted a permanent fix for the problem?


Cheers

Hi,
I had the same thing happen on my Asphalt, was quite frightening when it first happened especially as I had only had it a couple of weeks. Anyway dealer in Chester booked it in, knowing immediately what it was and it was fixed under warranty. Happy days!

New sensor fitted, the one with the new wiring harness, not the housing.
They say they've had 100% success with them, they checked the rest or the car over and said everything else is tip top, and that my oily custard is just condensation from low mileage.

I'm a happy bunny again :dance:

Yes the one with the harness is the modified modified fix

I've had this temperature fault issue now on three previous occasions and the last fix was the harness fix as described above. However, when I don't have the heating turned on in the car I still get the temperature start to rise straight away from cold and then drops back down to zero again when the heating is switched on and then rise normally.
Any ideas anybody as the dealership don’t seem to know?

Does it trigger any codes as in illuminate the EML? If not then this could be difficult to solve. Maybe have the dealership try another modified modified replacement just in case you got a bad one? If that does not fix it then I would hope your dealership will report it to Peugeot for them to fix it with a new modified modified modified fix

Hi.
I doesn't trigger anything on the display and this was the reply I received from the dealership:
"Good After noon Peter

Regarding your temp gauge we have a rcz on our sales pitch so i have been out to test that one to see if that is the same as yours and to be honest it seems to do the same as yours apart from you said your gauge goes back to zero when the heating is on this one drops considerably but not to zero i think it is when you have the heating on it takes the heat away from your engine and cools in down that why the temp gauge drops"

The temp gauge should not react the way you describe it does, mine does not do that. So the dealerships response is irrelevant in my books. I have never liked electrical gauges as they are problematic, direct reading gauges are best but today's cars they all use electronics.

If the temp gauge is reading the coolant temperature it will start in the cold area then gradually increase, then when the engine gets to the operating temperature it may drop a little as the thermostat opens (it is usually closed until the engine temperature reaches a desired temperature and then lets cooler coolant from the radiator into the engine and now all of the coolant is flowing with air flow assisting cooling with the movement of the car along with cooling fans to keep it all constant. When in heavy traffic it may go higher but the fans will keep it cool, but a working system will not over-heat etc.)

I've had my heating off since I picked it back up on Monday as it's been quite warm weather and my temp gauge climbs slowly to 90 degrees and stays there,exactly the same as it did prior to the fault with the sensor.

Is there another pug dealer that you can try or a pug specialist for a 2nd opinion?

he is speaking utter tripe.. your heating gauge should stay at 12 oclock 99% of the time. :beer:

Hes not 100% wrong. I used to have to put my heating on full blast in my 206 to stop it from overheating in traffic.

But its not relevant to the problem.
