V70 MY11 Auto: Cabin Temperature Sensor: where + cost
V70 MY11 Auto : Cabin Temperature Sensor – location and replacement cost – Error CCM-B1A6115
Can anyone give me some guidance as to the fix for the error “CCM-B1A6115 Cabin Temperature Sensor. General Electric Failures to battery or open”, please? I’m wondering, if the sensor needs to be replaced what’s a reasonable cost? I think the part itself is about £70 but I can’t find much on what the time to replace is likely to be except one comment on a video suggesting that on right hand drive (RHD) cars, you have to take out the dashboard. The background is that I noticed the aircon was a bit weak recently and as the wife’s car needed a re-gas, I took advantage of a 2-car discount and got the AC on both serviced (not just re-gassed but service, with vacuum check etc.). I was guessing that as the Volvo had barely been used for 2 years, the seals had dried and it had lost gas. Turns out there was plenty of gas (~500g out of ~800 spec) and no leak. AC still not cold and also the engine fans didn’t come on even when the engine and AC had been running for >15min. Hooking up the computer showed the error above. The mobile chap recommended a AC specialist garage in the area so I’ve booked it in for a diagnostic. In the meantime, I’ve been doing some research and using the car (but only short runs). Guess what – the AC seems to be working well, though I’ve not heard the fans spin up until I did a longer run today and they did fire up. When I said to the garage that it seemed to be working, they said that there could be enough air movement just from the car moving to cool the radiator but also pointed out that even if the engine isn’t that hot, the fact the AC is on is sufficient to make the fans kick in. They’re going to do the diagnostics tomorrow whilst I try to prepare the wallet for the impact. |

I always thought it was in the centre console, behind the little vent below the right side temperature dial?

Thanks @ferg55 , Yes, I think you’re right. The trouble for me is my car is non-standard and I have to rely on on-line schematics which show the sensor as an associated but separate unit from the CCM.
My car is ex-police so the centre console has been modified to house the various computers, cameras, radio etc. I have no little vent below the right hand temperature dial to give me a clue. Your info is useful (to me and others) as there is so little info on this version of the centre console. |

Update on AC diagnostic
Well, it’s a non-story and an ongoing saga.
Thanks to ferg55 for the info above. The non story version is – there wasn’t a problem (well, not a new one) detected. The error message is because the sensor is completely missing. During the car’s modification for police use, the sensor (and even the slot into which it fits) was completely removed. Had the mobile air-con chap used a fuller diagnostic then I’d have seen all the other – “where’s my radio”, “where’s my amp”, “why are my breaks so big”, “why’s my speedometer so sophisticated” etc. messages . It seems the car functions fine without this module and there’s no cross-impact on the engine cooling/heating. The ongoing saga is: I may have an intermittent fault (goody goody, lucky me 😉 ) The AC was definitely not on top form so I booked the service. It was definitely not blowing cold (maybe cool but not cold) during the post-service test. It has worked well since. Just like it did between when I thought it wasn’t and the service (hmm.. ). So, I’m hoping it’s a low battery voltage issue so the car is spending the night on charge. Then, let’s see how it goes. |
