Code B2113 Dodge Description

The B2113 diagnostic trouble code for Dodge vehicles indicates a 5-volt supply circuit low problem. This code is usually triggered when the Engine Control Module (ECM) detects that the voltage on the 5-volt reference circuit is below the specified range. The 5-volt supply circuit is crucial for various sensors and components in the vehicle to function properly. When the voltage drops below the acceptable level, it can lead to erratic behavior in the vehicle's systems, affecting performance and potentially causing long-term damage if not addressed promptly.
