Hello

Where is Interior air Temperature Sensor Citroen C4 mk2 1.6 e-HDi 2012?

Thanks..

There isn't a physical sensor!

The passenger compartment temperature is calculated from the following elements:

• External temperature sensor
• Sunshine sensor
• Air flow and distribution

The calculation depends on several parameters stored when the vehicle stopped, such as:

• External temperature
• Calculated passenger compartment temperature
• Day, date, time, second (this information makes it possible to calculate for how long the vehicle has been stationary)

On this vehicle, the passenger compartment temperature is not measured but calculated from a temperature assessment: Result of the sum of the power added and removed (This assessment is made for each zone).

What is this? There is product for C4 MK2 called: internal temperature sensor HELLA 6PT 009 104-151

I think that Diesel Air reheating is not working too. So no warm from it and not Warm from heating cell. Heating cell get hot and blower motor works but no heat to capin.

BSI reset...I have not tried yet.

That's not a Citroen part number, but it looks to be an evaporator sensor.

The evaporator sensor measures the temperature as near as possible to the actual evaporator, so that it can stop the air conditioning to prevent the evaporator from freezing. As I explained you do not have an internal temperature sensor - there is no such sensor on most PSA cars - it is calculated as I described.
