Code U1454 Dodge Description

The U1454 diagnostic trouble code for Dodge vehicles indicates that the engine control module (ECM) has detected implausible data being received from the gated park switch. The gated park switch is a component of the transmission system that is responsible for ensuring the vehicle is in the proper gear selection, particularly when shifting into park. When the ECM receives data from the gated park switch that is inconsistent or out of range, it triggers the U1454 code. This can lead to issues with the vehicle's transmission system, potentially causing erratic shifting, difficulty in engaging gears, or even preventing the vehicle from starting.
