P204C DODGE code

The trouble code P204C can be explicated as Reductant Pressure Sensor Circuit Low. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present.

What is a reductant pressure sensor?

The Reductant Pressure Sensor is used to monitor and control the amount of DEF the Reductant Pump is putting out. If the Reductant Pressure Sensor sends back an implausible signal, code P204B is set.

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 a reductant pump?

The Reductant Pump transfers the DEF (Diesel Exhaust Fluid) from the tank to the DEF Injector. If the Reductant Pump fails to perform as requested by the engine computer (PCM), code P208A will be stored.

How do you fix reductant pressure too low?

How To Correct Reductant Pressure Too Low Issue

  1. You must fix the defective reductant pump.
  2. Make sure to mend the faulty reductant injector.
  3. It is essential to restore the flawed reductant purge valve.
  4. Repair or replace the quirky reductant pressure line.
  5. Rehabilitate the defaults in the reductant pressure sensor.

What is reductant in a car?
