Code P1497 MINI Description

The P1497 MINI diagnostic trouble code indicates a downstream throttle air leak in the vehicle. This means that there is an issue with the air intake system after the throttle body, causing a disruption in the airflow. The throttle body is a vital component that controls the amount of air entering the engine, which is crucial for the combustion process. When there is a leak downstream of the throttle body, it can lead to an imbalance in the air-fuel mixture, affecting the engine's performance and efficiency.

  • 2008 Mini Cooper S. Just finished replacing thermostat housing, vacuum pump and valve cover. After about 4 miles I get CEL and code P1497 and code PO507. Any suggestions would be appreciated.

  • You should start by inspecting the repair you did. You may have left a loose hose or connector. Sounds like a leaking vacuum hose.

  • Well, that would be the most obvious so that is what I have already done. Hoping for a little more definitive explanation of what Mini's code P1497 indicates.
