The P208A 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 fault code could be a faulty Reductant Pump, an open or shorted Reductant Pump harness, or a poor electrical connection in the Reductant Pump circuit.

The repair importance of this fault code is high as it can lead to increased emissions and reduced fuel efficiency.

The difficulty level of repair is moderate, and it takes approximately 1.0 hour to fix.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p208a fault code.

Here are the symptoms to look out for:

  • The P208A fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, engine misfires, rough idling, reduced engine power, poor acceleration, decreased fuel efficiency, and stalling.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving.

The automobile fault code p208a can be caused by a faulty reductant pump, open or shorted harness, or poor electrical connection.

  • The automobile fault code P208A 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.

To fix the p208a automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p208a, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • Estimated repair time for this fix is 1.0 hour.

The fault code is P208A.

The estimated repair time is 1.0 hour.

The cost of fixing the fault code depends on the repair time. Most auto repair shops charge between $75 and $150 per hour. These factors are influential in determining the overall cost of diagnosing and fixing the automobile fault code.

The P208A code refers to the reductant pump control circuit or O. The reductant pump assembly contains various components such as a pressure sensor, a purge valve, and an internal heating element. The Powertrain Control Module (PCM) regulates the system pressure by controlling the pump speed using pulse width modulation.

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 system is primed and the injector provides DEF to the SCR catalyst as determined by the PCM. When the vehicle is shut down, the PCM closes the injector and actuates the reductant purge valve, causing the pump to reverse flow and bleed down pressure on the reductant pressure line.

The PCM then opens the injector to allow gas to enter the reductant pressure line, which in turn allows the pump to purge all remaining DEF from the system and return it to the reductant tank. 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 P208A automobile fault code?

If your engine light is on and you’re seeing the P208A fault code, it could be due to 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 pins.

How can I visually inspect the wiring harness and connectors related to the Reductant Pump?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to 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, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you identify the root cause of the problem and take the necessary steps to fix it.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection, follow these steps. First, check the “Possible Causes” listed above. Then, visually inspect the related wiring harness and connectors. Finally, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you fix the issue of the Engine Light ON (or Service Engine Soon Warning Light) caused by a faulty Reductant Pump, Reductant Pump harness being open or shorted, or Reductant Pump circuit poor electrical connection.
