What does trouble code P2445 mean?

The P2445 fault code indicates that the secondary air injection system pump is stuck in the off position on bank 1 of the engine. This system is designed to reduce emissions by injecting air into the exhaust system during cold start conditions, helping to facilitate the oxidation of unburned fuel and lower harmful emissions.

  • The secondary air injection system typically consists of a pump, valves, and various related sensors.
  • When the system fails to operate correctly, it can lead to increased emissions and may trigger the check engine light.
