I have the dreaded 3 light problem with my 2009 Scion xB. My Engine Light, Traction Light, and VSC light came on. It idles rough below 1000 RPMs and I'm not sure what the idle RPM even needs to be. It shifts rough, and at 55 mph its steady at about 5000~ RPMs.

My Fiance checked the resistance on the two transmission speed sensors and they both are in spec. 660 ohms or so.

Not sure what else could be causing the problem???

ANY help is greatly appreciated. I have searched all over (from Google) and have not found any other suggestions.

Hope this describes the problem with enough detail. We do not have much money and we are trying to stay away from the dealership if possible.
