The P2085 fault code in automobiles refers to a problem with the Exhaust Gas Temperature Sensor 2 (EGTS2) circuit.

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 due to exhaust leaks, faulty EGTS2, poor electrical connection, excessive particulate matter buildup on the sensor, or a faulty Engine Control Module (ECM).

The importance of repairing this issue lies in the fact that it can lead to decreased fuel efficiency and increased emissions.

The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2085 fault code. Here are the symptoms to look out for:

  • The P2085 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 stalling, and difficulty starting the engine.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2085, including exhaust leaks and faulty sensors.

  • The automobile fault code P2085 can be caused by several factors.
  • These include exhaust leaks, a faulty Exhaust Gas Temperature Sensor (EGTS) 2, an open or shorted Exhaust Gas Temperature Sensor 2 harness, poor electrical connection in the Exhaust Gas Temperature Sensor 2 circuit, excessive particulate matter buildup on the sensor, and a faulty Engine Control Module (ECM).

To fix the p2085 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage.

  • To fix the automobile fault code p2085, 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.
  • Ensure that everything is in good condition.
  • The estimated repair time for this fix is 1.0 hour.

The automobile fault code P2085 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the P2085 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2085 code refers to a problem with the Exhaust Gas Temperature Sensor 2 Circuit Intermittent. The Exhaust Gas Temperature Sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas.

The Engine Control Module (ECM) supplies 5 V to the exhaust gas temperature signal circuit and supplies a ground to the low reference circuit. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the Exhaust Gas Temperature Sensor resistance has changed greater than a calibrated amount in less than 1 s.

What are the possible causes of the automobile fault code P2085?

If you see the engine light on or service engine soon warning light, it could be due to the P2085 fault code. This code can be caused by exhaust leaks, faulty exhaust gas temperature sensor 2, open or shorted exhaust gas temperature sensor 2 harness, poor electrical connection in the exhaust gas temperature sensor 2 circuit, excessive particulate matter buildup on the sensor, or a faulty engine control module. To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P2085 fault code in my automobile?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light with a P2085 fault code, it could be due to exhaust leaks, faulty Exhaust Gas Temperature Sensor (EGTS) 2, or a poor electrical connection in the Exhaust Gas Temperature Sensor 2 circuit. Excessive particulate matter buildup on the sensor or a faulty Engine Control Module (ECM) could also be the cause. To fix the issue, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

What are the symptoms of the P2085 fault code in an automobile?

If you see the Engine Light ON or Service Engine Soon Warning Light in your automobile, it could be due to the P2085 fault code. This code is caused by exhaust leaks, faulty Exhaust Gas Temperature Sensor (EGTS) 2, open or shorted Exhaust Gas Temperature Sensor 2 harness, poor electrical connection in Exhaust Gas Temperature Sensor 2 circuit, excessive particulate matter buildup on sensor, or a faulty Engine Control Module (ECM). 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.
