What causes check engine and VSC lights to come on?
Have the codes scanned at a local auto parts store to pinpoint the problem. Post the code back here and we can help.
I went to the local Auto Zone in town and they helped with the check engine light but said their scan was not sophisticated enough to scan for the Vsc light. At any rate they provided PO446,Po455 and PO441. The probable causes were listed anywhere from loose gas cap to evaporative emission system, evap.canister or hose not connected , vacuum leak at engine,purse or solenoid defective and oh, yes, vacuum leak at engine.. I don't think I can handle all of that, for sure. Before I posted my question I had reset the check engine light, it blinked =, went off, Great, but when I started the car again, it shone brightly along with the light.VSC, I hate to have to bring this to a mechanic as I always feel when one sees an older woman , I don't know if I'm getting a fair shake. BTW, thank you so much for your prompt response.
All those codes are related to a EVAP and or vacuum leak. Try the cheapest fix and purchase a new gas cap and see if the light goes out in a day or 2.
My mom also has a 2005 highlander. She had the same problem with these two lights (vcs & check engine) and when she took it in it was just that the throttle fuse needed to be replaced & they tightened the battery cables. The Toyota deal ship didn't even charge for doing this.
My check engine light is on and vsc light is too. I put my car in drive and my car barely even moves
