Code P1403 Ford Description

The P1403 Ford code indicates that the Differential Pressure Feedback Electronic (DPFE) sensor hoses are reversed. The DPFE sensor is a crucial component of the vehicle's exhaust gas recirculation (EGR) system, which helps to reduce emissions and improve fuel efficiency. The DPFE sensor measures the pressure difference between the exhaust gas in the EGR system and the atmosphere, allowing the engine control module (ECM) to adjust the EGR flow accordingly.
