Code P140F Ford Description

The P140F Ford code indicates that the Exhaust Gas Recirculation (EGR) throttle is stuck in a specific position. The EGR system is responsible for recirculating a portion of the engine's exhaust gases back into the combustion chamber to reduce emissions and improve fuel efficiency. When the EGR throttle is stuck, it can disrupt the proper operation of the EGR system, leading to issues with engine performance, emissions, and fuel economy.
