Definition:
Exhaust Gas Temperature Sensor Circuit Low – Bank 1 Sensor 4
Description:
The Exhaust Gas Temperature (EGT) Sensors are used by the Powertrain Control Module (PCM) to monitor the engine exhaust temperatures in the aftertreatment system. The EGT Sensors are thermistors and change resistance based on the temperature being measured. EGT Sensors receive a 5-Volt signal from the PCM and share a sensor ground. The PCM monitors the change in signal voltage and converts this to a temperature value. The PCM illuminates the Malfunction Indicator Lamp (MIL) when the diagnostic runs and fails after two consecutive drive cycles. The PCM will turn off the MIL lamp after the diagnostic passes on four consecutive drive cycles. The PCM will disable active regeneration mode.
