The P2047 code means a fault is present in the reductant injection valve circuit, bank 1 unit 1. The reductant injector is used to reduce emissions gases exiting the exhaust by injecting either air or chemicals depending on the usage and vehicle.
What is a reductant valve?
OBD-II Code P2047 is defined as a Reductant Injection Valve Circuit/Open. Diesel Exhaust Fluid (DEF) is used to assist in converting leftover exhaust particles to harmless gases. In order to burn off those particles, the temperature of the exhaust system needs to increase.
What is code P202E?
The P202E error code is known as reductant injector- circuit range/performance bank 1 unit 1. This error will be set in the vehicle if the PCM determines the voltage in the control circuit which is out of the predictable or suitable range.
What is a reductant injector?
The reductant injector is used to reduce emissions gases exiting the exhaust by injecting either air or chemicals depending on the usage and vehicle. When the ECU detects the fault in the reductant injector circuit, it will set the P2047 code and the Check Engine Light will be displayed on the dashboard.
What does reductant pressure too low mean?
OBD-II Code Powertrain Control Module (PCM) failure is defined as a Reductant Pressure Too Low. Diesel Exhaust Fluid (DEF) is used to assist in converting leftover exhaust particles to harmless gases. In order to burn off those particles, the temperature of the exhaust system needs to increase.
What is reductant level?
The Reductant Level Sensor tells the engine computer (PCM) how much DEF is left in the tank. If the PCM sees that the DEF level is too low, code P203F is set. Additional warnings may be present on the instrument cluster. Failure to add DEF fluid may result in the engine not restarting until more DEF fluid is added.
