Installation and fault finding

EMS Caution UK

Removal and installation

  1. Disconnect the EGTS connector, loosen the mounting thread nut and remove the EGTS. It is recommended to remove it with an open-ended torque wrench due to long wires and thread rotates separately to sensor body.
  2. Install the new EGTS  with the specified tightening torque value by car maker. Connect the EGTS connector. Turn the engine on and check if the exhaust system works properly.

Fault finding

Possible failures 

Severe vibration can break the connection of inner wires, excessively high temperature (over 900 degrees Celsius) can cause resistance deviation of thermistor element, and severely bent wires (smaller than 20mm for bending diameter) can cause wire breakage.

  • Decreased fuel efficiency: DPF regeneration can take longer time, resulting in increased fuel usage.
  • Poor Driveability: DPF regeneration can occur at shorter interval than normal, and cause inconvenience during driving.
Prevention and Solutions 

A problem with the EGTS can cause the engine warning light to turn on. This fault is stored as a diagnostic trouble code (DTC) in the engine ECU and can be inspected by a DTC scan tool. If the root cause of failure is a defective EGTS, it will need to be replaced.
