SERIES 50 EXHAUST TEMPERATURE SENSOR FOR THE SERIES 50G ENGINES
The Exhaust Gas Temperature Sensor is threaded into the exhaust pipe within 12 inches of the turbocharger turbine outlet in the top half of the pipe. The devise is a temperature sensor that provides an electrical signal to the ECM. The sensor is electrically connected to the ECM through the engine sensor wiring harness. Temperature data from the sensor is used for engine protection and diagnostics.

The Exhaust Gas Temperature Sensor is non-serviceable and must be replaced as an assembly. No adjustment is required.
Removal of the Exhaust Gas Temperature Sensor
Remove the exhaust gas temperature sensor as follows:
Disengage the connector from the engine sensor harness.
Loosen the nut remove sensor from the exhaust pipe.
Installation of the Exhaust Gas Temperature Sensor
Install the exhaust gas temperature sensor as follows:
Insert in fitting in exhaust pipe.
Connect sensor to engine sensor wire harness.
