This Special Instruction outlines the steps needed to handle and install NOx sensors. NOx sensors are used in many different applications. Examples of applications include Clean Emissions Modules (CEM) for off-road applications, and different Selective Catalyst Reduction (SCR) systems used in stationary engine applications.Do not perform any procedure contained in this publication or order any parts until you have read and understand the procedure.Required Parts

Do not unplug the NOx sensor cable when the sensor is powered on. Damage to the engine ECM may occur.
Avoid impacting the NOx sensor, dropping the sensor could cause permanent damage. If the sensor is impacted, discard the sensor.
Handle and store the NOx sensor in a clean, dry area that is free of contamination, and inclement weather.
Do not remove the sensing unit protective cap
