P204B: Affordable Fix For Your Car
The automobile fault code P204B can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing the P204B fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.
P204B: Fuel Pressure Sensor Circuit Low Input
The P204B fault code is related to the Reductant Pressure Sensor in the Reductant Pump and Sensor Assembly. The Reductant Control Module supplies 5 V to the reductant pressure sensor on the 5 V reference circuit and provides a ground on the low reference circuit. The reductant pressure sensor provides a signal to the Reductant Control Module on the sensor signal circuit relative to the pressure changes in the reductant system.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the reductant pressure sensor signal is open or shorted to ground.
