What is P20FF? P20FF is a manufacturer-specific powertrain diagnostic trouble code (DTC) that indicates a problem with the reductant control module performance. This code is commonly seen on diesel vehicles equipped with a Selective Catalytic Reduction (SCR) system to reduce NOx emissions. When this code is triggered, it means the engine control module (ECM) has
