Introduction: Secondary Air Injection Pump Replacement in a 2006 Toyota Sequoia

In October 2016, I experienced a Secondary Air Injection Pump failure in my 2006 Sequoia. Toyota had extended the warranty on this part, but even though I had just 149K miles on the odometer, my car was a 2006 and the warranty only went back to 2007. I decided to replace the smog pump and its associated valves myself. I am an aircraft mechanic and have worked on my cars since college days so this repair did not look particularly daunting. I made this 3 part video to show Sequoia or Tundra owners what is involved, the expense, and where to get the parts as cheaply as possible. This video would also be of help to anybody having a Sequoia/Tundra of a year model with the smog pump located under the Intake Manifold. It should be noted that the first video in this series would ALSO apply to any Sequoia or Tundra of this vintage needing a Starter replacement, a new Intake Manifold Gasket, or one that has a Cooling System Leak under the intake manifold.

I must now do this a second time on my Tundra. I thank you for clear, concise, well photographed presentation.

Obviously that is a weak link and Toyota should have done better. I missed the cut-off on the recall by about a month (I think) and they would not give it to me.
Thanks for kind words.

A weak link for sure. Now I'm having trouble finding a decent quality aftermarket secondary fan. One that has positive reviews is "out of stock - unavailable until further notice." I don't want to spend $500+ on OEM.
I spoke with Hewitt Technologies about their bypass systems, but I never got a warm fuzzy that I wouldn't be in the lurch at some point, and their Gen 2 kit is as much as all the parts I would need to do the repair.

I hear you. There was one YouTube viewer that bought an after-mkt smog pump that he took the guts out of and put them into the Toyota casing. I think it was a Dorman pump that looked identical to a Chevy pump...

Question 1 year ago on Introduction

Hi Dave,

Do you have a copy of the notebook you created with the part-numbers for this job titled, "Secondary Air Injection Pump Replacement in a 2006 Toyota Sequoia"? If so, would you be willing to share it with me? My wife's 2005 sequoia is having the same issues, and I'm trying to save money by completing the job myself.

- Francisco
