If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p205d fault code.

Here are the symptoms to look out for:

  • The P205D fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, rough idling, poor acceleration, decreased fuel efficiency, engine misfires, and stalling.
  • It can also cause the vehicle to fail emissions tests and emit excessive exhaust fumes.
  • If you experience any of these symptoms, it is important to have your vehicle diagnosed and repaired by a qualified mechanic as soon as possible to prevent further damage.

The automobile fault code p205d can be caused by a faulty reductant pump and sensor assembly, open or shorted harness, poor electrical connection, or a faulty reductant control module.

  • The automobile fault code p205d can be caused by a faulty Reductant Pump and Sensor Assembly.
  • It can also be caused by an open or shorted Reductant Pump and Sensor Assembly harness.
  • Another cause can be a poor electrical connection in the Reductant Pump and Sensor Assembly circuit.
  • Lastly, a faulty Reductant Control Module can also trigger this fault code.

Below are the possible fixes for the automobile fault code p205d, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p205d, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P205D 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 P205D fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P205D fault code is related to the Reductant Tank Temperature Sensor. This sensor measures the temperature inside the reductant tank and sends the signal to the Reductant Control Module. If the difference between the reductant temperature sensor signal and exhaust gas temperature sensor signals is outside a calibrated range, the Diagnostic Trouble Code (DTC) will be set.

The P205D code specifically indicates that there is a high voltage in the Reductant Tank Temperature Sensor circuit.

What are the possible causes of the P205D fault code and how can they be checked?

If you’re experiencing the P205D fault code, which is indicated by the engine light being on, it could be due to 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.

How does a faulty Reductant Pump and Sensor Assembly affect the engine and trigger the P205D fault code?

A faulty Reductant Pump and Sensor Assembly can trigger the P205D fault code, causing the engine light to turn on. This can be caused by a faulty assembly, an open or shorted harness, poor electrical connection, or a faulty Reductant Control Module. To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

What steps should be taken to fix the P205D fault code and prevent it from recurring in the future?

To fix the P205D fault code, first check the possible causes such as a faulty Reductant Pump and Sensor Assembly, open or shorted harness, poor electrical connection, or a faulty Reductant Control Module. Visually inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector pins.
