Replacing Yaw Sensor help - 04 XC90 T6

[armaheadon]

I promise I searched the forum and didn't see anything specific. I just had my XC90 diagnosed at a Volvo dealer with a faulty Yaw Sensor (Getting Anti-Skid Service Required). They want to charge $780 for the repair. I decided to roll the dice and just bought a $200 salvaged sensor as I read in this forum that the repair is fairly easy. Has anybody swapped out this sensor? If so, can you help me with some of the steps to get to it. What I know is that it is under the passenger seat (US)...and I was just going to start taking stuff out till I found it.

Thanks.

My repacement sensor cost about £450 fitted. The sensor is very sensitive and requires careful handling. Given it's importance to the saftey of the XC90 I wouldn't begrudge the cost.

All the best.

Cost me about £500 fitted at the dealer. Would rather they did it than do it myself.

I had a Volvo specialist do mine. Charlewood Volvo. They did it while I waited. Took about half an hour including checking that the fault codes had gone.

MC,
Remove the amp unit under the seat , first thing to do is check for evidence of a water leak , this should be addressed before you do (anything else) , if there is a sign of leakage it is most likely the sunroof drains.
The sensor is held in with 2 bolts , it takes a little wiggling to get out , DO NOT BEND THE BRACKET .
Depending on the code you had yaw sensor problems can be fixed with a simple vibration damper.
Hope this helps , Mister T.

Michael.... I don't know the story in the USA but my UK 2003 XC90 already had the viration damper fitted when it failed. It's the little black rubber pad you can see in the photos, and if you can bend that bracket taking it out you must be a front runner for the strongest man in the world.

Thanks for this great advice! I should get the part tomorrow and will report back on how it goes. Thanks. MC

Success..... I installed the salvaged sensor last night. The help you all gave was great. Thank you. It was definitely a tight space to work in, but I managed to do it all in under 30 minutes. I had one hiccup...once I was done and I reconnected the battery and started the car, I got a new message "Anti-Skid Temporarily Off". I was concerned...but was optimistic since they were nice enough to include 'temporarily' in the message. Thinking it may need a kick-start.. I took a spin around the block and on the first turn I hit the brakes (I wasn't going that fast) and I felt the ABS kick in a little and warning message instantly went away. Drove 30 miles today without it coming back on.. so I think I am back in business. Thanks again!

Well done. It's great to fix something yourself isn't it?

I did try to find a repairer for my unit but didn't have any joy on the internet.

All the best.
