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.
Here’s the background on this problem, what’s happening, and what you can do if this problem effects your Tundra.
