Engine warning light and vsc and vsc off light went on while driving. Dealer indicated that a valve in the charcoal canister and the canister itself needed replacement. The components are part of the emissions system and the vsc is part of the same circuit hence both sets of warning lights went on. Dealer indicated that if you top off the tank the extra gas spills over into the canister and can overwhelm the valve causing excessive usage and possible shorting. I indicated that I have never topped off the tank in this car, dealer had no other explanation. Part is not covered under the Toyota $1800 extra care gold extended warranty, and cost to replace canister was $285. 00, and $31. 00 for valve, plus $285. 00 labor. Note:78k miles on vehicle, same exact problem on three other occasions:
new valve, vacuum swi installed, total charge $152. 11
diagnosis & clean sensor reinstall code, total charge $130. 50
diagnosis & reinstall code, total charge $43. 50
