A code P2179 in a Cadillac CTS indicates a problem with the throttle actuator control system, specifically related to the throttle position sensor. This code usually suggests that there's an issue with the throttle body or its connection, which can affect engine performance. Common symptoms may include poor acceleration, stalling, or a check engine light. It's advisable to have the vehicle diagnosed and repaired by a professional to prevent further issues.
