Some 2014-2015 Toyota Tundra trucks equipped with a 3UR engine may exhibit a MIL on with DTC P2440 (secondary air injection system switching valve stuck open bank 1) and/or P2442 (secondary air injection system switching valve stuck open bank 2). The condition may be caused by debris/ice in the air switching valve assembly. The ECM logic has been changed to reduce the possibility of this concern. Reprogram the ECM with the latest calibration.
