The exhaust gas temperature sensor is used by the Powertrain Control Module (PCM) to monitoring the exhaust gas temperature. The PCM constantly checks the range and the high temperatures can be an indicator of dangerous conditions that can lead to catastrophic engine failure. Excessively high exhaust gas temperatures are the result of a rich air/fuel ratio.
