While driving the car these lights came on. Vehicle ran the same as before the lights came on. I suppose if I needed the Vehicle Skid Control then I may have a problem.
Check engine light came on and also VSC light. What can the problem be? on 2002 Lexus RX300
Don't be worried that because several warning lights are on that there are several problems. Many sensors are shared between the engine and transmission control, and the traction control and anti lock brake circuit. One sensor failure can cause several systems to fail, or appear to fail. A scan tool is needed to retrieve these codes in your car.
You should check out clublexus.com for lots of good free advice on these error codes. My first guess is that the MAF sensor is dirty and needs cleaning. Lots of good photos and DIY tutorials on the above site on how to clean it. I've had this error code and resolved it by cleaning the Mass Air Flow (MAF) sensor.
