P2480 GMC Code - Exhaust Gas Temperature Sensor Circuit/Open Bank 1 Sensor 5
Quick Answer
The P2480 GMC code refers to a fault in the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 1 Sensor 5. Common causes include Faulty EGT Sensor: The sensor itself may be malfunctioning, leading to inaccurate temperature readings, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause an open circuit, ECM Malfunction: A problem with the Engine Control Module can prevent proper communication with the EGT sensor. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2480 GMC Description
The P2480 GMC code refers to a fault in the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 1 Sensor 5. This sensor is responsible for monitoring the exhaust gas temperature in the specific bank and sensor location. If the sensor circuit is open or not functioning properly, it can lead to issues with the engine's performance, fuel efficiency, and emissions control.
Common Causes of P2480 GMC
- Faulty EGT Sensor: The sensor itself may be malfunctioning, leading to inaccurate temperature readings.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause an open circuit.
- ECM Malfunction: A problem with the Engine Control Module can prevent proper communication with the EGT sensor.
- Exhaust System Damage: Physical damage to the exhaust system, such as a leak or blockage, can affect sensor readings.
- Electrical Issues: Problems with the vehicle's electrical system, such as a blown fuse or relay, can disrupt the EGT sensor circuit.
Symptoms of P2480 GMC
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Reduced Engine Performance: You may experience a decrease in engine power or overall performance due to incorrect temperature readings.
- Poor Fuel Efficiency: A faulty EGT sensor can cause the engine to run inefficiently, leading to increased fuel consumption.
- Rough Idling: The engine may exhibit rough idling or stalling due to inaccurate temperature data.
- Increased Emissions: Faulty EGT sensor readings can result in higher emissions output, potentially causing the vehicle to fail emissions tests.
How to Fix P2480 GMC
- Diagnostic Testing: Use a diagnostic scanner to retrieve the trouble codes and pinpoint the issue with the EGT sensor circuit.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test EGT Sensor: Test the EGT sensor for proper functionality and replace if found to be faulty.
- Verify ECM Function: Ensure that the Engine Control Module is functioning correctly and communicating with the sensor.
- Clear Codes: After completing the repairs, clear the trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2480 GMC
The cost of repairing a P2480 GMC code can vary depending on the specific cause of the issue and the labor rates in your area.
