Review on 🚗 Dorman 911-643 Secondary Air Injection Check Valve: Ideal for Lexus and Toyota Models by Wayde Lash

Great solution! Cleared code p2440 on our Sequoia 08. The pumps can also be problematic (obviously water is getting into them). I took ours out and examined them but they looked dry and fine. That part worked, but it was an all-day routine. You have to remove the air intake and a thousand vacuum lines to get there. Also, he's in a difficult position, so I watched YouTube videos with tips, which helped a lot. I'm not a mechanic but the dealer wants 3k-4k for it so I took a chance
