Code P2444 GMC Description

The P2444 GMC code indicates that the secondary air injection system pump is stuck on. This system is responsible for injecting fresh air into the exhaust system to help reduce emissions. When the pump is stuck on, it can lead to an imbalance in the air-fuel mixture, causing the vehicle to run rich. This can result in decreased fuel efficiency, increased emissions, and potential damage to the catalytic converter. The pump may be stuck on due to a mechanical failure, electrical issue, or a problem with the control module.
