On the 2005-2013 Toyota Tundra, the secondary air injection pump is prone to failure due to water intrusion. The electric motor is located in the wheel well with moisture exposure, and the rubber boot covering the motor traps water, causing the pump to short circuit. This triggers check engine lights with codes P2440, P2443, P2445, P2447, P0418, or P0419. Some vehicles may enter limp mode.

This issue also affects: Toyota 4Runner, Toyota Tacoma, Lexus GX

Common Symptoms

  • Check engine light illumination
  • Jet engine noise on cold startup
  • Decreased fuel economy
  • Limp mode activation
  • Rough idle when cold

How to Fix

Toyota issued a service bulletin for 2007-2010 models covering replacement of the entire air injection system. Repair costs range from $2,000-$4,000 for OEM replacement. Some owners opt for aftermarket bypass kits with block-off plates.
