Code P0906 Dodge Description

The P0906 diagnostic trouble code (DTC) for Dodge vehicles refers to the "Gate Select Position Circuit Low." This code indicates that there is an issue with the gate select position sensor circuit being below the expected voltage level. The gate select position sensor is responsible for detecting the position of the gear selector in automatic transmission vehicles. This information is crucial for the transmission control module (TCM) to accurately determine which gear the vehicle should be in. When the gate select position circuit is low, it can lead to incorrect gear selection by the TCM, resulting in poor vehicle performance, drivability issues, and potential safety concerns.
