New Tundra Air Injection System Bypass Module Available

A new solution is available for Toyota Tundras and Sequoias that have malfunctioning air injection system. Tundra Headquarters first ran an article “Tundra and Sequoia $4000 Air Injection System Problem”┬áin 2010 when the stories of outlandish repair costs to the nonessential system began flooding forums and blogs. While Toyota has since warrantied the air injection system on 2nd generation (2007 and up) Tundras and Sequoias, this warranty isn’t perfect:

  1. There is no warranty for 1st generation Tundras or Sequoias that have this problem
  2. The warranty ends after 10 years or 150k miles

However, a custom module being offered by a TundraSolutions.com member promises to “fix” your air injection system for less than $100.

This custom module tricks your Tundra or Sequoia into thinking that the air injection system is functioning properly.

Tundra and Sequoia $4000 Air Injection System Problem

UPDATE: As of November 2011 (nearly 18 months after this problem first came to our attention), Toyota has finally announced a special service campaign to cover this repair. You can learn more about Toyota’s Air Injection Pump Extended Warranty Campaign here.

It’s been brought to our attention that many 2007 or 2008 Tundra owners are being asked to replace their truck’s air induction pump assemblies and/or air injection switching valves at a substantial cost. The pumps and/or valves seem to be malfunctioning at about the same time that Toyota’s 3 year/36k mile warranty ends, sometimes at a total cost of more than $4,000. Obviously, this is a major concern for any 2007 and older Tundra owner.
