I had the same problem with my 2007 Avalon xls. I took it to AutoZone and they tested it and said it was because my gas cap was'nt tightened tight enough, so i tightened it till it clicked, then disconnected the battery connections for 30 seconds to reset the check engine and VSC light and i have'nt had a problem since!

Update I had to replace the gas cap....no more problems !

Thank you, farmboy! My husband didn't believe it would work when I told him. But 2 minutes later, success!! Although my husband said to note that the check lights will go off after a time of the error not happening. Whatever, this gave me peace of mind much sooner!

I followed Farmboy93 advice on the gas cap. I tightened the gas cap and unhooked the battery then hooked it back up and the VSC & check engine lights went off. However they came back on. So i bought a new gas cap repeated the process and the lights went off again. So this morning they're bacl on. Has anybody had an actual problem that cause those lights to come on that had to be fixed other the it being a issue with the gas cap? Any suggestions?

Thank you! Prayed for fix and found the answer here. New Toyota gas cap and disconnecting reconnecting battery worked. Labor Cruise Control also working now ! Praise Jesus

2005 Avalon both Check Engine and VSC lights on. 3 months ago, gas cap tightening to click fixed it. This time issue was misfiring cylinder with bad ignition coil. Needed periodic maintenance of changing spark plugs too. Service guys explained that the system tries to protect itself when it gets this type of error, so it actually could have shut down the engine. I noticed a brief shutdown twice during acceleration. it also turned off the cruise control. There is another pesky player possibly tripping these lights: the various oxygen sensors in the exhaust stream. Again, system protection may shut down engine to prevent too much unburned gas going out to the catalytic converter, which would get very hot processing it. Sensor can be expensive to replace.

2006 Avalon Limited with check engine and VSC lights on. Lazor Cruise Control would not stay engaged. Bought new Totota replacement gas cap from dealer and disconnected/reconnected battery. Lights went off and Labor Cruise Control working for 3 weeks now! My Lord Jesus led me to this site; Praise Him! Additional thanks to farmboy!

Thank You Farmboy93. Per your instructions I tightened the gas cap, unhooked the battery for about 60 seconds, then hooked it back up, and the VSC & check engine lights went off. It has been a week and the two lights have not come back, but I did notice that my gas cap plastic threads are barely engaging with the gas tank outlet, and a very slight push, pushes the gas cap out. After 175,000 miles maybe time to change the gas cap!
