Code P20F5 RAM Description

The P20F5 diagnostic trouble code (DTC) indicates that the vehicle's reductant consumption is too high. Reductant, often referred to as diesel exhaust fluid (DEF), is a crucial component in modern diesel vehicles equipped with selective catalytic reduction (SCR) systems. The reductant helps reduce harmful emissions such as nitrogen oxides (NOx) by converting them into harmless nitrogen and water vapor. When the vehicle's reductant consumption is too high, it can lead to inefficient emission control and potentially harm the vehicle's overall performance.
