c5 temperature reading
Hi all my c5 hdi 110 02 thinks its currently around 40c or 105f outside when its around 1c in reality,is the sensor easy to find and change and does the ecu rely on this reading for fuelling information as it could explain my mpg being around the 40mpg mark rather than a little higher?
While im here il drop another question regarding my drivers door window/electric mirror controller console,windows would go down on both sides but not up [well handy eh?]. Passenger side would go up with its door controller only and drivers side up on turning wipers on full speed, until one wet night when drivers side stay down until dismantled door card and placed in a wooden prop!! Im leaning toward replacing the drivers door switches from citroen dealer to hope that clears it up unless someone else can share a similar problem. One last thing for the moderators could the citroen forum have its own subdirectories to make finding car related problems more specific as currently searching is problematic due to getting all types of citroen model show up rather than just the model your looking for.{Not a complaint this is still the best forum}.

Had similar problem with my passenger front window. Would go down with drivers door window control but only up by pressing passenger window switch. Popped out drivers door window control and took it apart and gave it a good clean. Seemed to be gunked up with maybe spilt soft drink (previous owner) and fluff. Works now good as new and was amazed at ease of fix.
Can confirm C5 temp sensor is on under side of passenger wing mirror. You can remove mirror glass by gently prising off with screwdriver from behind. This then gives you access to four (I think) plastic tabs which hold on colour coded main cover. These are bu**ers to remove but if you can get it off should be able to cut wires to temp sensor and remove. You may find it easier to remove whole wing mirror first but this involves first removing door card and inner trim.

Does anyone have spec for the just the temp sender?
I know people say they are cheap from the dealers but to me cheap is the 50p or so that just the sender would be from an electronics supplier!

thanks
Thanks for the prompt replies guys on both issues ill be prizing glass sometime soon,the c5 was pretty untidy when i got it and i still have the switches for the drivers door so they'l be dismantled and cleaned soon. Im surpsised the c5 doesnt take a temperature reading from somewhere outside for its fuelling though as most modern inject wether petrol or diesel?

It doesn't use the outside air temperature reading at startup for glow plug operation?

A while back when mine was still under warranty I had the same problem of false reading. I took it into the dealer and he said it needs to be changed asap as the ecu uses the reading to run properly. They did it there and then.

The glowplug operation is controled depending on engine temperature (which it gets from the coolant temperature sensor).Paul-R wrote:It doesn't use the outside air temperature reading at startup for glow plug operation?
If you think about it the engine could be at 95 degrees but the outside air temp could still be minus 5, The engine certainly wouldnt need glowplugs on startup then.
