[SOLVED] P2084 Code: Fixing Exhaust Gas Temperature Sensor Circuit Issues

The P2084 fault code in automobiles indicates a problem with the Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 2. 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 a faulty EGTS, open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor.

The repair importance is high as it affects the vehicle’s emissions and fuel efficiency. The difficulty level of repair 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 p2084 fault code. Here are the symptoms to look out for:

  • The P2084 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include a decrease in engine performance, rough idling, stalling, and difficulty starting the engine.
  • The vehicle may also experience a decrease in fuel efficiency and emit black smoke from the exhaust.
  • Additionally, the engine may produce a knocking sound, and there may be a noticeable smell of gasoline.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2084, including a faulty EGTS and exhaust leaks.

  • The automobile fault code P2084 can be caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 2.
  • It can also be caused by an open or shorted Exhaust Gas Temperature Sensor Bank 1 Sensor 2 harness.
  • Poor electrical connection in the Exhaust Gas Temperature Sensor Bank 1 Sensor 2 circuit can also trigger this fault code.
  • Additionally, exhaust leaks and excessive particulate matter buildup on the sensor can cause the P2084 fault code.

To fix the p2084 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2084, 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 fault code P2084 indicates a problem with the exhaust gas temperature sensor circuit. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the location of the shop, the severity of the issue, and the type of vehicle.

The P2084 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 P2084 OBDII code. This code indicates that there is a rangeperformance issue with the EGTS circuit in Bank 1 S.

What are the possible causes of the automobile fault code P2084?

If you see the engine light on or service engine soon warning light, it could be due to the P2084 fault code. This code is usually caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 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 check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors for the P2084 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2084 fault code, you may have a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 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 check for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P2084 fault code?

Ignoring the P2084 fault code, caused by a faulty Exhaust Gas Temperature Sensor or related issues, can lead to decreased fuel efficiency, engine damage, and increased emissions. It is important to check the possible causes, visually inspect the wiring harness and connectors, and look for damaged components to avoid further damage.
