Code P2054 Ford Description
The P2054 diagnostic trouble code for Ford vehicles indicates a problem with the reductant injection valve circuit on Bank 1 Unit 2. In vehicles equipped with Selective Catalytic Reduction (SCR) systems, the reductant injection valve is responsible for delivering the correct amount of diesel exhaust fluid (DEF) into the exhaust stream to reduce harmful NOx emissions. When this valve circuit is detected to be operating at a low voltage, it can lead to improper DEF injection, affecting the vehicle's emissions control system.
