The OBD-II code P1404 refers to an issue with the EGR (Exhaust Gas Recirculation) system, specifically indicating that the EGR valve position sensor is reporting a problem. This typically means that the sensor is malfunctioning, out of range, or there is a blockage in the EGR system. Common symptoms may include poor engine performance, increased emissions, or illumination of the check engine light. It's advisable to diagnose the exact cause and address any underlying issues to maintain optimal engine performance.
