Code P2160 Dodge Description

The P2160 diagnostic trouble code for Dodge vehicles refers to an issue with the Vehicle Speed Sensor 2 Circuit registering low voltage. The Vehicle Speed Sensor (VSS) is a crucial component in the vehicle's system, as it is responsible for measuring the speed at which your vehicle is traveling and sending this information to the engine control module (ECM). The ECM then uses this data to make adjustments to various systems such as transmission shifting, cruise control, and traction control.
