[SOLVED] P2086 Code: Fixing Exhaust Gas Temperature Sensor Circuit Issues

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2086 fault code.

This code indicates a problem with the Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2. The possible causes include a faulty sensor, open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor.

The repair importance is high as it can affect the engine’s performance and emissions.

The repair difficulty is moderate, and it takes around 1.0 hour to fix.

To interpret the fault code, you need to check the possible causes and visually inspect the related wiring harness and connectors.

Repair Importance Level3.33 (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 p2086 fault code. Here are the symptoms to look out for:

  • The P2086 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, and engine misfires.
  • Additionally, the vehicle may experience hesitation or stalling during acceleration, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p2086 can be caused by various factors, including a faulty sensor, poor electrical connection, exhaust leaks, and particulate matter buildup.

  • The automobile fault code P2086 can be caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2.
  • It can also be caused by an open or shorted Exhaust Gas Temperature Sensor Bank 2 Sensor 2 harness.
  • Poor electrical connection in the Exhaust Gas Temperature Sensor Bank 2 Sensor 2 circuit can also trigger this fault code.
  • Additionally, exhaust leaks and excessive particulate matter buildup on the sensor can cause the P2086 fault code.

To fix the p2086 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 p2086, 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 automobile fault code P2086 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 P2086 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P2086 code is related to the Exhaust Gas Temperature Sensor (EGTS).

The EGTS is responsible for detecting exhaust gas temperature and converting it into a voltage signal. The PCM monitors the EGTS for proper circuit continuity and out of range high values. If the EGTS is out of factory specifications, the PCM sets the P2086 OBDII code.

This code indicates that there is a range or performance issue with the EGTS circuit in Bank 2 S.

What are the possible causes of the P2086 fault code?

If you notice the engine light on or service engine soon warning light, it could be due to the P2086 fault code. This code is usually caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the 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.

How can I visually inspect the related wiring harness and connectors for the P2086 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2086 fault code, you may have a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix this issue, check the “Possible Causes” listed above and visually inspect the related wiring harness and connectors. Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P2086 fault code?

Ignoring the P2086 fault code, caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2, can lead to serious consequences. The engine light will remain on, indicating a problem, and the vehicle may experience reduced fuel efficiency and performance. Ignoring the issue can also lead to further damage to the engine and exhaust system, resulting in costly repairs. It is important to check the possible causes and visually inspect the related wiring harness and connectors to avoid these consequences.
