Details of the Ford p20e9 OBD Code
The Ford P20E9 code indicates a problem with the reductant heater control circuit.
Ford OBD code P20E9 means that the Reductant Pressure Too High condition has been detected.
This code is triggered by the Powertrain Control Module (PCM) when it detects that the pressure in the reductant system is higher than expected.
The reductant system is part of the vehicle’s emissions control system and is responsible for reducing harmful emissions.
The system involves components such as the reductant pump, reductant pressure sensor, and reductant injector.
When the pressure in the system is too high, it can indicate a malfunction in one of these components or a blockage in the reductant system.
