My problem is CODE P2195 in my car Lexus RX 350

SOURCE: message reads 'check VSC' with engine light on?

ur vsc light will come on whenever you have a check eng light on. best thing to do is bring ur car to a local and have them scan ur car. your car should still be under factory warranty any repairs wont cost u anything.

just from my experience a 2007 ES with a check eng light is most likely a faulty a/f sensor or a loose gas cap

you most likely have an "air gap" or "tone ring" problem with one of your sensors or tone rings. i would suggest letting a technician diagnos which problem it is, as it is a diagnosis that requires some experience.

Hi, did you ever get an answer? I have the same issue. Thanks.

I'm not sure about the Lexus, but Nissan and other vehicles with the VSC usually will be on until you can drive on a straight road for approximately 2-3 miles without stops and about the same speed during the reset process. The interstate or some type of hwy will reset this light once the vehicle has learned the Vehicle Stabilization Control in which is learned by the way you drive and enables the car to have stable control. Hope this helps out, if this doesn't work, I would take it in for more diagnostics.
