Code P0405 Chrysler Description
The P0405 Chrysler code indicates a problem with the Exhaust Gas Recirculation (EGR) Position Sensor Circuit being low. The EGR system recirculates a small amount of exhaust back into the engine's intake manifold to reduce combustion temperatures and lower the formation of harmful emissions. The EGR position sensor is responsible for monitoring the position of the EGR valve and ensuring it opens and closes correctly. When the sensor detects a low voltage signal, it triggers the P0405 code, indicating a potential issue with the EGR system.
