External Temperature Indicator Has Started To Show Wrong

Hello, I searched the forum but opened a new topic because I could not find any results. The external heat shield on my vehicle has stopped working correctly for a few days.
Namely; When the outside temperature is around +5 degrees, the value on the screen on my vehicle can be like 0 or -1 and even lower. I tried whether the sensor is working with my hand or other heat sources, it shows the changes.
Is there anything happened to this problem before, can something like this happen because the water, mud, etc. has escaped to the sensor?
My vehicle is 2004 307 XT Gasoline / LPG, thanks in advance.

it may be contaminated yes.

Probably in the last bits of his shoulder. If you want, you can go to a cleaning path. Maybe there is oxidation or fluid contact on your legs and this is causing extra resistance. For Sensor I once put the sema into the forum. You can find Aratip. Koliva 2011-04-11 12:23:48

I looked at your messages but I couldn't find it, if you would like to add it again, would you add the scheme you mentioned.
Does this sensor have a new one, or is it a problem if it is this way?

So let me put a whirlwind

It does not cause any problems to work in this way. This sensor has no contribution to the operation of the engine. Only if it shows a minus, the flashing soner on the screen is so. I think it's not expensive. There is a sponsor in the forum, if you write in its title, it will tell you the price.

The sky above seems to be of no use to you because it was an answer to tell where the sensor is.
To remove the sensor, as Metin said, you completely break the mirror (metaphorically, so you tend to tilt it). ). In this way, you can open the clip inside by inserting a long screwdriver through the gap. Cut the wires and remove the sensor. When you install the new one, you solder it in place. Otherwise, you will have to defrag the new cable again.

I do not know your name, do not look at my fault, Mr. Koliva; I do not know correctly, I do not need to remove the door trim to remove this sensor, that is, I just need to disassemble the mirror.
I will follow up for a few days, then if I can find the sensor, I will try to remove and renew it, but of course it is a matter of finding the sensor.

It should be as Metin said. You can also test if there is an ohmmeter when you remove the sensor. He needs to read resistance.

If you find a PTC Thermistor it will work, but now I can't remember your full information. Generally, water enters the mirror from there and oxidation occurs in its connector, it is not a circuit element that can deteriorate under normal conditions.

The problem with the temperature sensor continues, I think there is no other solution to change.
Does this sensor malfunction create a problem in the operation of the digital air conditioner, do you know about it?

When I turn on the digital air conditioner, when I press auto, I know that he is adjusting his own temperature according to the temperature of the interior.

cem brother said schema, and I came to mind koliva (:

I run the air conditioner in the morning for trial purposes, a compressor comes into play, it turns out (idle) and cold air did not come, it came to my mind that it might be due to low external temperature, I ran it at 20 degrees.

I also have the same vehicle, it usually shows 3-4 degrees low in mine. But this has nothing to do with automatic air conditioning, at least not in my car. Let's say its content in cold weather is 24 degrees in auto mode. If you leave the door slightly open, the fan will start at full speed. volkan_uysal 2011-04-21 12:58:22

In a vehicle without digital air conditioner, the electric heater was also activated when we started the heating (without the vehicle running) because the outside temperature indicator showed wrong. A similar system can plot.

I said I will be hooking the subject, but I am not going to hurt another subject. How can I clean the sensor without inserting the sensor?
