Code P2480 Description

The P2480 code indicates a problem with the Exhaust Gas Temperature (EGT) Sensor Circuit/Open in Bank 1 Sensor 5. This sensor is responsible for monitoring the temperature of the exhaust gases in the exhaust system. The EGT sensor helps the engine control module (ECM) adjust the fuel mixture and timing to optimize engine performance and reduce emissions.
