A system and method for detecting an air leak within an engine is provided. The engine includes an intake manifold communicating with an engine cylinder. The method includes measuring an exhaust gas constituent in exhaust gases from the engine when the engine is operating in an idle operating mode. The method further includes determining whether the air leak is present in the engine based on a measured exhaust gas constituent, a first air-fuel correction value, and a second air-fuel correction value.
