[SOLVED] P208D Code: High Control Circuit – Fix Your Reductant Pump Now!

The P208D fault code in automobiles indicates a problem with the Reductant Pump system. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this issue could be a faulty Reductant Pump, an open or shorted Reductant Pump harness, or a poor electrical connection in the Reductant Pump circuit.

The importance of repairing this issue lies in the fact that it can lead to increased emissions and reduced fuel efficiency. The repair difficulty is moderate, with a repair time of 1.0.

To fix the problem, one 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 notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p208d fault code.

Here are the symptoms to look out for:

  • The P208D fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, decreased fuel efficiency, rough idling, engine misfires, engine stalling, reduced engine power, and difficulty starting the engine.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving.

The automobile fault code p208d can be caused by a faulty reductant pump, open or shorted harness, or poor electrical connection.

  • The automobile fault code p208d can be caused by a faulty reductant pump.
  • It can also be caused by an open or shorted reductant pump harness.
  • Additionally, a poor electrical connection in the reductant pump circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p208d, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p208d, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P208D indicates a problem with the exhaust gas temperature sensor circuit.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Other factors that may influence the cost include the location of the repair shop, the type of vehicle, and the severity of the issue.

It is important to address this fault code promptly to avoid further damage to the vehicle and ensure optimal performance.

The P208D code refers to a fault in the reductant pump assembly. The assembly contains a diaphragm pressure pump, a pressure sensor, a purge valve, an outlet filter, and an internal heating element.

The reductant pressure sensor provides feedback to the Powertrain Control Module (PCM), which regulates system pressure. When the PCM requests reductant injection, the reductant injector opens and the pump operates, filling the reductant pressure line and injector and purging air from the system.

The P208D code indicates that there is a high circuit in the reductant pump control. The PCM commands the glow plug control module to provide voltage to the reductant pump assembly internal heating element when the reductant temperature approaches 12°F (-11°C).

What are the possible causes of the automobile fault code p208d?

If you see the engine light on or the service engine soon warning light, it could be due to the P208D fault code. This code is usually caused by a faulty reductant pump, an open or shorted reductant pump harness, or a poor electrical connection in the reductant pump 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’s pins.

How can I visually inspect the related wiring harness and connectors to fix the p208d fault code?
