P2445: Secondary Air Injection System Pump Stuck Off Bank 1
3 vehicles · 1 makes · $300-$3,000 repair
Most Reported On
P2445 is an OBD-II diagnostic trouble code meaning “Secondary Air Injection System Pump Stuck Off Bank 1.” This generic emissions code means the secondary air injection (AIR) pump on bank 1 is not moving air when commanded to during cold-start operation. The secondary air system briefly pumps fresh air into the exhaust at startup to help burn off the rich cold-start mixture and reduce emissions, and the PCM detects no airflow or pump activity. It is primarily an emissions/inspection concern and rarely affects how the car drives, though it should be repaired to pass smog testing. This code is most commonly reported on 2008-2019 Toyota Sequoia, 2005-2011 Toyota Tacoma, and 2005-2009 Toyota 4Runner, with repair costs ranging from $300 to $3,000.
