P2445 code definition
Secondary Air Injection System Pump Stuck Off Bank 1
What the P2445 code means
The secondary air injection system is designed to pump outside air into the exhaust in order to help reduce harmful emissions. This trouble code indicates that the powertrain control module has detected a malfunction with this system on the bank 1 side of the engine.
What are the causes of the P2445 code?
The most common cause of this trouble code is a failed air injection pump. The air injection pump is designed with a check valve inside which only allows air to flow in one direction, preventing exhaust gases from escaping through the air pump and only allowing air to enter. When this check valve fails, moisture is able to get inside the air pump.
During the winter months this moisture can freeze, causing the air pump to seize up and possibly break. Other possible causes of this issue would include damaged wiring or connectors associated with the air pump, blown fuses, or a broken serpentine belt
