Hi all. New to the forum as I just purchased my first Volvo, a 2003 Volvo XC90 with only 158,000km (98,000miles) on it . I have to say I love the vehicle! When I purchased it the previous owner told me a list of problems that he said were all caused by the corroded yaw sensor under the amplifier/passenger seat. Doing a bit of research it seems most of what he says is true but I'm not sure the other symptoms are caused by that sensor. Here is a list of cautions I've got on the dash and some symptoms:
- ABS light
- the exclamation in triangle light
- SRS airbag service urgent
- Time for Regular service
- Anti Skid Service Required
- Bulb failure position light (likely unrelated?)
- No power to radio (although it did power up briefly this morning, there was no LCD screen to do anything, just static then nothing)
- the steering wheel "kicks" every so often, especially noticeable in suburb/town driving, not spots noticible on highway
- last but not least, a clicking sort of noise when backing up.

Interested to hear your thoughts on how badly I'm screwed and if most of these things could be related to the yaw sensor.
Thanks,
Shawn

 

The ABS light and Anti-Skid Service Required message are related to the yaw sensor.

The exclamation triangle is on any time there is a message in the message center.

Time for Regular Maintenance is just a service reminder. It does not indicate a fault and can be reset. Search YouTube for the procedure.

Bulb Failure Position Light means you have one or more taillight bulbs out.

The rest is not related and would need further inspection ans diagnosis.

 

Thanks, pretty much what I figured, except I believed him that the pulsing in the steering wheel was related.

 

So before I start looking at junkyards for a yaw sensor and ICM, does anyone know what years were compatible with my 2003 XC90?


Thanks
