Code P0405 Dodge Description
The P0405 code for Dodge vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) Position Sensor Circuit being low. The EGR system is an essential part of the vehicle's emissions control system, reducing nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the intake system. The EGR position sensor is responsible for monitoring the position of the EGR valve, ensuring it opens and closes at the appropriate times to regulate exhaust gas flow. When the sensor detects a low voltage signal, it triggers the P0405 code, indicating a potential issue with the EGR system's operation.
