P204A: Fuel Rail Pressure Sensor Circuit Low Input
The P204A fault code refers to the Reductant Pressure Sensor Circuit. The Reductant Pressure Sensor is located in the Reductant Pump and Sensor Assembly.
It responds to pressure changes in the reductant system and provides a signal to the Reductant Control Module. The Diagnostic Trouble Code (DTC) will be set when the Engine Control Module (ECM) detects that the reductant pressure sensor signal is open or shorted to ground.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P204A fault code. This code is caused by a faulty reductant pressure sensor, an open or shorted reductant pressure sensor harness, or a poor electrical connection in the reductant pressure sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to a faulty Reductant Pressure Sensor or an open/shorted harness.
