We are glad that we could be of help. Would you please consider showing your support so that we can continue to help other Toyota Owners. Support ToyoHeadquartersCheck Eng/Trac Off came on last Thursday on my 2012 Prerunner. My mechanic read the codes and told me the parts would be $2100. plus for the Air Injection System parts. He also told me about the Toyota Warranty Extension. Clearwater Toyota agreed to look at the truck Friday morning. They said that "yes the repair would be covered". The truck was ready at about 2:00 in the afternoon, no charge, thank you very much. They didn't even show how much it would have been without the warranty extension. Very classy I think.
