P204D: Affordable Fix For Your Car
The automobile fault code P204D can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the P204D fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.
P204D: Fuel Pressure Sensor Circuit Low Input
The P204D 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 ECM is connected to the Reductant Control Module via the CAN bus.
The DTC will be set when the ECM detects that the reductant pressure sensor signal is open or shorted to ground. The P204D Code indicates a Reductant Pressure Sensor Circuit High.
FAQ
If you see the engine light or service engine soon warning light on your dashboard, it could be due to the P204D fault code. This code is triggered by a faulty Reductant Pump and Sensor Assembly, an open or shorted harness, poor electrical connection, or a faulty Reductant Control Module. 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’s pins.
When the P204D fault code appears, the engine light or service engine soon warning light turns on, indicating a problem with the Reductant Pump and Sensor Assembly. To identify if the Reductant Pump and Sensor Assembly harness is open or shorted, check for poor electrical connections, a faulty Reductant Control Module, or damaged components. Visually inspect the related wiring harness and connectors, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P204D fault code, start by checking the Reductant Pump and Sensor Assembly circuit for a good electrical connection. Visually inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector pins. This will help ensure that the fault isn’t caused by a poor electrical connection.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Reductant Pump and Sensor Assembly, open or shorted harness, poor electrical connection, or a faulty Reductant Control Module.
Check the possible causes, inspect the wiring harness and connectors, and look for damaged components or corroded pins.
