check engine and trac off light on

this is the second time now on a 2013 4wd tacoma reg cab. it happened a few days after some heavy downpours. i didn't take it in because it cleared up the next day. it has happened again after more heavy rains last week and the weekend. i am figuring a sensor is getting wet somewhere. it will at times kill engine power also but that is an intermittent thing. it just don't make sense considering all the rain we have had this summer.

has anybody else had this happen?

 

I had a similar situation after intermittent rain for 24 hours "Trac off" and "check engine" lights are on. I will call it in tomorrow when they are open. [2012-prerunner-sr5-2wd-12143 miles]
