I have a 2007 Prius 91000 miles, never had an issue always been great. Suddenly at 60 mph on the interstate the VSC lite, Check engine lite, and master warning lites came on. WE pulled off the road, powered down the vehicle and let it sit for a minute. We re powered the car and it powered up immediately. The VSC lite went off but others are still on. the car appears to run fine (65 on the interstate or in town speed). The fuel cap is on tight. any ideas?

I talked to you on the live chat, and I think that you may have missed the end of my typing...

What I went on to say is that more often than not, on the 02 4Runners, the Check and VSC lights in tandem look mainly after the emission system, and, since you stated no issues during the road test, I would guess that it is a fuel issue (too full/loose gas cap). But, if you can get the vehicle scanned, I will be very glad to provide you with more and better info if you provide me with the DTC codes. That would require your guy or an autozone hookup to a scan tool. I hope my clarification helps; and the graciouness of a FIxYa rating for this question would be greatly appreciated

You need to hook it up to an anyliser to find out the codes.

SOURCE: vsc lite still on

the problem is more than likely the aftermarket catylitic convertor is setting the check engine and vsc light off- have someone- Auto-Zone etc- bypass the code with their handheld computer and it might not come back on.
Replacement catylitic convertors other than those installed by Toyota will set off your sensor for some reason or another.
hope this helps,
