I recieved these codes before (LAST WEEK Thursday)
Control System Mal-Function
Evap Emission system
Incorrect Purge Flow
Evap Emission Control Sys
Vent Control Circuit Malfunction
What I did was disconnect the neg. battery cable for about 15 minutes and boom, the light waws gone for a whole week. Last night it rained (As did last week Thursday) and this morning I found the light on again after driving for about 5 minutes. All the other days, it didnt' rain at all. I was wondering, could it been the rain affecting some part to make my light come on? And, for Toyota to look at this prob, I am assuming it's not free of charge aye?
