ADDITIONAL INFORMATION
Introduction
Some 2012 – 2013 model year Sequoia and Tundra vehicles equipped with 3UR engines may exhibit
a MIL “ON” condition with the following Diagnostic Trouble Codes (DTCs):
• P2440: Secondary Air Injection System Switching Valve Stuck Open Bank 1
• P2442: Secondary Air Injection System Switching Valve Stuck Open Bank 2
This condition may be caused by debris/ice in the air switching valve assembly. The Engine Control
Module/ECM (SAE term: Powertrain Control Module/PCM) logic has been changed to reduce the
possibility of this condition occurring. Use the following procedure to reprogram the ECM (PCM).
