MrBSI: Thank you. I think I have found some interesting threads now. Off for a read. Any more posting on fault codes and ECU reading will now be on a new thread.I think this should stay with my original thermostat problem from here on.

On my 2001 1.4i there is only engine temp and air-intake temp reading in diagnostics.
No oil temp reading on the dash either so I assume there is no sensor for it. |
Both temp gauges on mine show around the same reading once the engines up to running temp after driving for a few minutes, coolant temp gauge is below rev couter & oil temp gauge on right.

Mine is doing this, i've got the thermostat which i'll try first, if that doesn't do it then i'll try the sensor and if that doesn't do it .... i'll hit things with a hammer until they do work

SteveTDCi: why not get some OBD software and ELM lead and compare your water temp from the ECU against the gauge reading. This should tell you if your gauge is reading accurately and the thrmostat is at fault.
A quick check for thermostat stuck open or partially open = start the car from cold. Keep your hand on the top radiator hose. if the hose warms up slowly with the engine then the thermostat is not fully closing. That is a thermostat failure. If the hose suddenly gets hot that is thermostat opening when the water gets up to temperature.
This is a reasonable basic test but on some thermostats the springs eventually get weak and they will open in a rush but open early.

Thanks, I've got the thermostat already so I'll try that first, the lead software and laptop will make it expensive

New coolant temp sensor time, common issue on the TU lumps 
I only found out my thermostat was faulty aswell after I changed the coolant temp sensor

Yeah its next on the list, i just need to let them know which one i have since I'm told there are several, mines just a two wire one. It smells like its running a little rich so i'll change the temp sensor first before going elsewhere

Check the colour of the connector plug, some are green & others blue.
Just match the colour & you cant really go wrong.

Mine had a problem with temp recently,When I start the car,the temp reach the 70,and stay on the 70 mark for long time of driving like 20-30 min. then after that the temp reach the 80 and after a while hit the 90 mark and after driving for longer time,the fan on low speed kicks in after 90 and get it back to 90 sharp.
So I changed the thermostat,and still the same,nothing changed,so I guess it's time for a new temp sensor,and hopefuly this will solve the problem,because car is running rich,and consume more pertol now :(.
Any suggestions before I do that?

Re-written now (tonight) that I have found the blue sensor that is so well hidden - though not changed yet
When stood still the indicated temp slowly rises to just under 90 and the cooling fan cuts in. Temp drops quickly to just over 80 and fan cuts out.
Normal driving and it is still holding 70.
Everything now points to the sensor except I think it has high fuel consumption.
My daughter does short runs between 4-6 miles and rarely more. She is a very steady driver (and, I believe, steady even when her parents aren't in the car) and is getting 28mpg. Is this normal in these temperatures for a 1.4 8V petrol LX. It seems quite high to me. My son has a 51 plate 16V 1.6 Alfa 147 and drives it much, much harder. He drives similar short trips and is getting 31mpg.
I am not looking to tangle the sensor and thermostat but will probably change both!
The car has done 57,000 miles, is recently serviced with all filters, fluids and plugs renewed. If this consumption is high is there anything else that is a common problem that can cause this? I don't think it pulls quite as hard as I expect but there is no misfiring either hot or cold, it does not use water and no signs of head gasket problems. The plugs, changed 1,500 miles ago, were a very good colour.
One thought is that the timing belt had been changed before we bought the car. Does anyone know if these will run without valves meeting pistons if the valve timing is one tooth out? Is this a possible cause?

Thermostat and sensor now changed (genuine Peugeot supplied items) and thermostat was stamped 89 . Gauge now fluctuates between 82 and about 88 so while I think that is a little low I will treat it as correct.
I had intended to change one item at a time but my daughter was in a hurry for the car so both got done at the same time; doing both while in a rush made sense to me at the time but now typing it out it no longer seem logical! Anyway it does mean that I will not know if it was the stat or the sensor.
I just hope it helps improve the mpg.
