Code P20A5 Ford Description
The P20A5 Ford diagnostic code refers to the Reductant Purge Control Valve being stuck closed. This valve is a crucial component of the vehicle's Selective Catalytic Reduction (SCR) system, which is responsible for reducing harmful emissions by injecting a urea-based solution (commonly known as AdBlue) into the exhaust stream. When the Reductant Purge Control Valve is stuck closed, it prevents the proper flow of the urea solution, leading to a decrease in the efficiency of the SCR system and an increase in emissions.
