Code P0120 Dodge Description

The P0120 code for Dodge vehicles refers to an issue with the Electronic Throttle Control (ETC) motor performance. The ETC system is responsible for controlling the throttle opening in response to driver input. The throttle body houses the ETC motor, which adjusts the throttle plate position based on signals from the vehicle's Engine Control Module (ECM). When the ECM detects that the ETC motor's performance is outside the expected range, it triggers the P0120 code.
