Nice one mate!! Just completed this on our 2004 Volvo V70. Fast and easy. Only required the 13mm wrench/socket, T25 bit/screw driver, bone tool, and replacement part. Thank you BigTallTim!!
An excellent video and accompanying commentary. It took me two hours to complete the job with just one problem which was shifting the retaining pins holding the door panel. My pins did not have the inner pins to poke in so I resorted to brute force carefully applied. Four of the eight broke! The final result was I now have a working outside temperature display. I measured the resistance of the original thermistor as infinity, an open circuit. The new one was about 2.5kohms at room temperature and about 6.0kohms at around -15 degreesC. Well done for helping me so well.
Excellent tutorial- comprehensive in the steps to take at a pace one can follow . Thank you - you saved me a 200.00 mechanics quote on installation of a part that was priced under 20.00 !
@@bigtalltim, Hello again. Ok here is a weird one. I have a LHDrive 2002 XC70. I replaced the driver-side (Left) ambient sensor. No temp reading on the dash. I then replaced the right (passenger) ambient sensor and the dash (DIM) now reads the outside temp. My vehicle is possessed.
@jonpulicicchio5000 that *is* weird! According to the wiring diagrams it should always be via the drivers door module! At least you are sorted now - and thanks for the update!
Great video, how did you figure that was your problem? Did the car's dashboard show a much lower outside temp or did you have to go through VIDA? Have an intermitent ac problem so trying to figure out diagnosis
Hi - I used a diagnostic computer (CR-Max). If you check the temperature in the data stream for the drivers door module, it will give you a good clue… as I recall, mine was registering something like minus 111C which was clearly not right. I did another vid for the XC90 with the diagnostic process: ruclips.net/video/SjTXN0Md3cY/видео.html
My 2005 Volvo XC70 has both driver side and a passenger side Ambient Temperature Sensors located under the rear view mirrors. Any idea what the passenger side sensor does?
Hi Roy - I do indeed... it doesn't do anything! The same mirrors are used for left and right hand drive options, so it just saves them some cost on manufacturing... I believe the active one will be on the drivers side whichever variety you have, as it is controlled by the drivers door module. If you look at the data stream for the door modules in a diagnostic computer, the passenger side will show 0
In principle, yes! I deliberately took apart the "spare" side of an S60 and was surprised to discover that in fact it did contain an active sensor, and not the blanking plate that I was expecting! HOWEVER... it is likely that if one sensor has failed that the other one could also be on its way out or already dud, so better to spend the 17 quid on a new one - they are one of the cheapest sensors in this car!
I’m afraid I don’t, but if you pop into a local autofactors with your registration plate they will be able to advise the correct part based on the published build list for your vehicle… it might not be in the mirror for an s40
Great question, and in my case no. The crazy temperature was reported on the data stream in my diagnostic computer; the dash showed approximately the correct temperature.
Hi James - if one side is blowing cold it may be a different issue… a diagnostic computer will confirm whether the sensor is sending dodgy data. The dealership or any motor factor would be able to confirm the exact part you need from your registration plate or VIN number - there are some differences for different years… don’t want to give you a bum steer!
There are a couple of temperature sensors involved… what is your cabin temperature sensor reading on the diagnostic computer? That is the little one that has 3 slots in the dashboard over the temperature dial… the do get dusty and covered in fluff - may be worth blowing some compressed air through the 3 slots to clear out any fluff… after that, check the pressure of your a/c system, and the state of the serpentine belt… lastly, the a/c system has a 15amp fuse - should be in the satellite fuse box under the hood for most Volvos… check that out - it is not uncommon for them to blow
I know this was posted a long time ago but im having an issue with my 2002 V70 D5 with manual climate control. Im getting CCM-001E and CCM-001A which mean temp knob and fan knob faulty signal. This causes the motors that regulate the heat to keep moving and my ac doesnt blow constant cold in hot weather. Interestingly my CCM reads outside air temp at constant -40c. Did you have ACC or MCC? I dont know if it should read that value since its manual climate control and doesnt have any interior temp sensors. Cheap part so might try anyway. DIM displays correct outside air temp like yours, so where is that sensor located? Thanks in advance.
AC in Volvo’s can be a nightmare… the ambient temp sensor is in the r/h/s wing mirror, the cabin sensor is in behind the 3 small slots on your dashboard… fluff can be a problem (see my short) and as the temperature is determined based on resistance with a thermistor, corrosion in the connectors can also be a problem! As a workaround, manual settings on your ac should work - the temp sensor should only control “auto” mode… I have also heard of instances where folks relocate the temp sensor directly to the air intake (kinda like the old 850 position) and bypass the loom, wiring instead direct to the ecm pin… this apparently works, which suggests that the issue is corrosion in the loom - possibly under the footwell carpet if it gets damp… I suggest checking the green connector in the door for corroded pins, and cleaning out the dashboard sensor as a starter for ten!
@@bigtalltim ah allright. Well the rhs wing mirror reeds -111c and the ccm reads -40c. The thing is i have a complete manual ac panel no auto at all. I disassembled my panel and cleaned it an no more codes. Now im just waiting on the ambient temp sensor
@adriansmeds4800 sounds like you have a dodgy connection in the loom - extreme resistance is interpreted as extreme cold… as I mentioned before some guys have had success with connecting the temp sensor direct to the ecu pin - I’ve never done that, but will see what I can find about that for you… might be worth looking it up on the forums
Hey, thats what I was looking for, great vid, good job mate. But I can't find info which one is broken in my car. My s60 have steering wheel on the left side (eu version), I have correct tempreture on dash and im wondering which one is responsible for not working (manual) ac and p0073 fault. I wonder if you remember which one it would be 😅 I mean which side/mirror
I believe that it is always the drivers door - the data stream for the climate control module comes from the drivers door module… that said, it is easy to check! Plug in a diagnostic computer, and look at the CCM data stream, then put your palm on the bottom of the mirror. Even if reading way low like this one was, you will still see an increase from your hand temperature! Thanks for watching!
@@bigtalltim wow that was quick! I started digging groups and forums and you're probably right. I don't have diagnostic computer, only cheap obd2 toy and I checked everything that I could with it. But yeah, I should find out just using my hand or even lighter and looking to the dash which one it could be. Thanks a lot for your help!!! Stay safe my friend
You are very welcome! Make sure you check the cabin temp sensor as well - believe it or not, your problem could also be caused by fluff! ruclips.net/video/TmC3VBn2UQc/видео.htmlsi=vC9McGjE9Q1LKrVI
Too easy! Cheers.edit: I had a crack at this today on my 2006 V50. At 2:00 where you remove the triangular internal cover my car has what looks to be a small speaker.

yep - I had the same in my 04 S60... just a part of the stereo system - should be held in place with 3 pegs as I recall... watch out - they can get pretty brittle over time!

Thank you for the informative video. It appears I have one on each side on my 02 xc70.
Only one of them will be active - it should be the one connected to the driver door module that connects to the ECU… thanks for watching!
I thought as much. Thanks again.

Only one of them is connected - you need to plug a computer in and read the data stream from the door modules… what volvo do you have by the way?
Sorry about this but do you have an ambient Sensor part number for. My Volvo S40 Lux DG57ONW plate
I’m afraid I don’t, but if you pop into a local autofactors with your registration plate they will be able to advise the correct part based on the published build list for your vehicle… it might not be in the mirror for an s40
Did the outside temperature in the speedo cluster show a low reading ?
Great question, and in my case no. The crazy temperature was reported on the data stream in my diagnostic computer; the dash showed approximately the correct temperature.
