P20F5: Your Car’s Fuel System Needs Attention
The P20F5 fault code is related to the Diesel Exhaust Fluid (DEF) consumption in the automobile. The Powertrain Control Module (PCM) monitors the DEF pressure in the supply line and compares it to the known DEF Supply Pump volume.
If the PCM detects high DEF consumption, it will illuminate the MIL light immediately after the diagnostics runs and fails.
The DEF injection into the aftertreatment system will be disabled, and the P20F5 code will be displayed, indicating reductant consumption too high.
