I have a Toyota Sienna 2004 yesterday
while driving the van accelerated and I
heard a pop followed by the VSC light
which flashed briefly and it took to the right
side. Seems fine now I'm still concerned
Is the check engine light coming on in combination with the VSC light? If so, is it flickering? The different codes the VSC warning light throws are usually PO446,Po455 and PO441. The probable causes are 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.. Let me know if you have any further issues or questions! Best of luck!
