P2083 GMC Code - Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 1

Quick Answer

The P2083 GMC code indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2, Sensor 1. Common causes include Faulty EGT Sensor: The most common cause of this code is a malfunctioning EGT sensor itself, Wiring Issues: Corrosion, damage, or poor connections in the wiring harness connected to the EGT sensor can also trigger this code, ECM Malfunction: A problem with the engine control module (ECM) can interfere with the EGT sensor circuit operation. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2083 GMC Description

The P2083 GMC code indicates a problem with the Exhaust Gas Temperature (EGT) sensor circuit on Bank 2, Sensor 1. This sensor is responsible for monitoring the temperature of the exhaust gases before they enter the catalytic converter. The EGT sensor plays a crucial role in ensuring the proper functioning of the emissions control system and optimizing the engine's performance.

Common Causes of P2083 GMC

  1. Faulty EGT Sensor: The most common cause of this code is a malfunctioning EGT sensor itself.
  2. Wiring Issues: Corrosion, damage, or poor connections in the wiring harness connected to the EGT sensor can also trigger this code.
  3. ECM Malfunction: A problem with the engine control module (ECM) can interfere with the EGT sensor circuit operation.
  4. Exhaust System Leak: A leak in the exhaust system before the EGT sensor can cause inaccurate readings and trigger this code.
  5. Sensor Placement: Incorrect placement or installation of the EGT sensor can also lead to circuit intermittent issues.

Symptoms of P2083 GMC

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
  2. Reduced Fuel Efficiency: A faulty EGT sensor can cause the engine to run inefficiently, leading to decreased fuel economy.
  3. Rough Idling: The engine may experience rough idling or hesitation when the EGT sensor is not functioning properly.
  4. Engine Misfires: In severe cases, a malfunctioning EGT sensor can cause engine misfires or performance issues.
  5. Increased Emissions: An inaccurate EGT sensor can result in higher emissions output, potentially causing the vehicle to fail emissions tests.

How to Fix P2083 GMC

  1. Diagnose the Issue: Use a diagnostic tool to read the code and pinpoint the exact cause of the problem.
  2. Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as necessary.
  3. Test EGT Sensor: Test the EGT sensor itself to determine if it is functioning correctly. Replace if faulty.
  4. Clear Codes: Clear the diagnostic trouble codes (DTCs) from the ECM after the repairs have been made.
  5. Final Test: Conduct a final test drive to ensure that the issue has been resolved and the Check Engine Light remains off.

Cost to Fix P2083 GMC

The cost of repairing a P2083 GMC code can vary depending on the cause of the issue and the specific vehicle. On average, the parts for this repair, including a new EGT sensor and any necessary wiring components, can range from $100 to $300. Labor costs can add an additional $100 to $200, bringing the total repair cost to approximately $200 to $500. However, it's important to note that labor rates and part prices can vary significantly based on factors such as location, vehicle make and model, and the repair shop's hourly rates.
