If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p205c fault code.

Here are the symptoms to look out for:

  • The P205C fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience a decrease in acceleration or a loss of power while driving.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p205c 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 p205c 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.

To fix the p205c automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p205c, 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 is P205C. 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. Therefore, the fixing cost of P205C can range from $75 to $150.

The P205C fault code indicates a problem with the Reductant Tank Temperature Sensor circuit. This sensor measures the temperature inside the reductant tank and sends a 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 DTC will be set.

The code specifically indicates that the circuit is experiencing low voltage, which could be caused by a faulty sensor or wiring issue.

What are the possible causes of the P205C fault code in an automobile?

If you’re experiencing the P205C fault code in your automobile, you may notice that the engine light is on. This could be due to a faulty Reductant Pump and Sensor Assembly, an open or shorted harness, poor electrical connection in the assembly circuit, or a faulty Reductant Control Module. To fix the issue, it’s important to 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 one visually inspect the wiring harness and connectors related to the Reductant Pump and Sensor Assembly?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Reductant Pump and Sensor Assembly. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Also, check for an open or shorted harness and poor electrical connection in the Reductant Pump and Sensor Assembly circuit. Finally, check the Reductant Control Module for any faults.

What are the consequences of ignoring the P205C fault code in an automobile?

Ignoring the P205C fault code in an automobile, which indicates a faulty Reductant Pump and Sensor Assembly, can lead to serious consequences. The engine light will remain on, and the vehicle may fail to pass emissions tests. The faulty assembly can also cause damage to the engine and exhaust system, resulting in costly repairs. It is important to address the issue promptly by visually inspecting the wiring harness and connectors and checking for damaged components.
