Code P0652 Dodge Description

The P0652 code for Dodge vehicles indicates a problem with the 5-volt sensor reference 2 circuit being too low. This sensor reference circuit is crucial for providing a stable voltage signal to various sensors within the vehicle, such as the throttle position sensor, fuel pressure sensor, and more. When this circuit voltage drops below the specified range, it can lead to incorrect sensor readings and potentially affect the performance of the vehicle. This issue can trigger the Check Engine Light to illuminate and may cause the vehicle to go into a reduced power mode to prevent further damage.
