Code P2484 Chevrolet Description

The Exhaust Gas Temperature Sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas. The exhaust temperature sensor 1 is the first exhaust temperature sensor on the exhaust system, the following exhaust temperature sensors are counted upward from the engine outlet to the exhaust system end. 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 Exhaust Gas Temperature Sensor temperature information is used by the ECM during the exhaust gas particulate filter cleaning process. 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.
