The P2081 automobile fault code indicates a problem with the Exhaust Gas Temperature Sensor 1 (EGTS) circuit. This can be caused by exhaust leaks, a faulty EGTS, poor electrical connections, or excessive particulate matter buildup on the sensor. The engine light will turn on as a symptom.

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. The repair time is estimated to be 1.0. It is important to address this issue promptly to avoid further damage to the engine.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2081 fault code.

Here are the symptoms to look out for:

  • The P2081 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, engine stalling, rough idling, decreased fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may emit unusual smells or sounds, and the exhaust emissions may be abnormal.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2081, including exhaust leaks and faulty sensors.

  • The automobile fault code P2081 can be caused by several factors.
  • These include exhaust leaks, a faulty Exhaust Gas Temperature Sensor (EGTS) 1, an open or shorted Exhaust Gas Temperature Sensor 1 harness, poor electrical connection in the Exhaust Gas Temperature Sensor 1 circuit, excessive particulate matter buildup on the sensor, and a faulty Engine Control Module (ECM).

Below are the possible fixes for the automobile fault code p2081, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2081, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 factors that influence the cost of diagnosing and fixing the automobile fault code P2081 include the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges from $75 to $150. These are the primary factors that will impact the overall cost of the repair.

Other factors that may come into play include the specific cause of the fault code, the type of vehicle being repaired, and any additional parts or labor required to complete the repair.

The P2081 code refers to a problem with the Exhaust Gas Temperature Sensor 1 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.

The Exhaust Gas Temperature Sensor temperature information is used by the ECM during the exhaust gas particulate filter cleaning process.

What are the possible causes of the automobile fault code P2081?

If you see the engine light on or service engine soon warning light, it could be due to the P2081 fault code. This code can be caused by exhaust leaks, a faulty exhaust gas temperature sensor, poor electrical connection in the exhaust gas temperature sensor circuit, excessive particulate matter buildup on the sensor, or a faulty engine control module. To fix this issue, you should 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 one visually inspect the related wiring harness and connectors to fix the P2081 fault code?

If you’re experiencing the P2081 fault code, indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the related wiring harness and connectors. This fault code can be caused by exhaust leaks, a faulty Exhaust Gas Temperature Sensor (EGTS) 1, an open or shorted Exhaust Gas Temperature Sensor 1 harness, poor electrical connection in the Exhaust Gas Temperature Sensor 1 circuit, excessive particulate matter buildup on the sensor, or a faulty Engine Control Module (ECM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors for damaged components, broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P2081 fault code?

Ignoring the P2081 fault code can lead to serious consequences such as reduced engine performance, decreased fuel efficiency, and potential damage to the engine and exhaust system. The fault code indicates a problem with the Exhaust Gas Temperature Sensor 1, which can be caused by various factors such as exhaust leaks, faulty sensor, or poor electrical connection. It is important to address the issue promptly by visually inspecting the related wiring harness and connectors and checking for damaged components to avoid further damage to the engine.
