I started getting a anti skid message recently (again). It's been a few years since I replaced the sas and that seems to have fixed it, I'm guessing it's the same issue again. Is it worth the extra cost to get a new sensor vs a used one $420 vs $100-150? Or should I try to clean it? 2006 xc90 4.4 173,000

 

Update: Ebay $150 used, rock auto SMP brand $311.99, FCP Euro Volvo brand $418.89

 

You may as well try cleaning it, see my first ever post on instructions. Also I've read you can adjust the potentiometer on the SAS sensor board to decrease its resistance from about 300 Ohms to 250 to improve results as well.
