I recently had the check engine light illuminate at the same time the TRAC OFF light came on. I lost engine power. Had the code read and it indicated secondary air injection problem. Toyota has an issue with this listed on the tundra trucks. Federal government says emissions are covered for 96 months or 80000 miles. So riddle me this Batman. How can the air pump in this system be covered by Toyota but the equally expensive valve in this system not be covered. Anyone else have this issue with Toyota
