The P205A fault code in automobiles indicates a problem with the Reductant Tank Temperature Sensor. 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 sensor, an open or shorted harness, or a poor electrical connection.

It is important to address this issue promptly as it can lead to reduced fuel efficiency and increased emissions. The repair process involves visually inspecting the wiring harness and connectors for any damage or corrosion. The difficulty level of this repair is considered to be low, and it can be completed in approximately 1.0 hour.

To interpret the fault code, it is recommended to check the “Possible Causes” listed above and visually inspect the related components.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p205a fault code.

Here are the symptoms to look out for:

  • The P205A 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.

P205A fault code can be caused by a faulty sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code p205a can be caused by a faulty Reductant Tank Temperature Sensor.
  • It can also be caused by an open or shorted Reductant Tank Temperature Sensor harness.
  • Additionally, a poor electrical connection in the Reductant Tank Temperature Sensor circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p205a, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p205a, 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 P205A 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 P205A fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P205A code refers to a fault in 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 Diagnostic Trouble Code (DTC) will be set.

What are the possible causes of the P205A automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P205A fault code. This code is usually caused by a faulty reductant tank temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor 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 Tank Temperature Sensor?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Reductant Tank Temperature Sensor. 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. This will help you identify if the Reductant Tank Temperature Sensor harness is open or shorted, or if the circuit has a poor electrical connection.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P205A fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P205A fault code, you should visually inspect the related wiring harness and connectors. This will help you identify the cause of the problem and determine the appropriate fix. Check for any damaged components and look for any broken, bent, pushed out, or corroded connector’s pins. Once you have identified the issue, you can take the necessary steps to repair or replace the damaged components or connector’s pins.
