Code P20F6 Dodge Description
The diagnostic trouble code P20F6 for Dodge vehicles indicates that the Reductant Injection Valve in Bank 1 Unit 1 is stuck open. The Reductant Injection Valve is a crucial component of the Selective Catalytic Reduction (SCR) system, which helps reduce harmful emissions by injecting a urea-based solution (DEF or AdBlue) into the exhaust stream. When the valve is stuck open, it can lead to an improper injection of the reductant, affecting the overall efficiency of the SCR system and potentially causing an increase in emissions. This issue can trigger the check engine light and impact the vehicle's performance and fuel efficiency.
