Nitrogen Oxide (NOx) Sensor for
1204F-E44TA, and 1204F-E44TTA
Engines
Note: There are two NOx sensors. One sensor can
be installed in the flexible exhaust pipe assembly or
can be installed in the CEM. The other sensor should
be installed into the exhaust tail pipe at a suitable
position.
Note: The first NOx sensor has a black cable. The
NOx sensor that should be installed in the
exhaust tail pipe has a gray cable. If the sensing
unit is installed in the wrong location, a
diagnostic code will be come active.
Certain transportation, storage, and handling
recommendations are listed below:
• Shipping boxes should be transported and stored
in a closed condition. Store the sensors in the
original, closed shipping box until the sensor is
ready for use. The maximum storage time in
production packaging boxes is 18 months after
production. The maximum storage time in spare
part packaging is 2 years after production.
• Sensors should be stored in a temperature range
of -40° C to 105° C.
• Handle and store the NOx sensor in a clean, dry
area, free of contamination, and inclement
weather.
• Avoid temperature shock when opening a shipping
box. Avoid a temperature difference of more than
±5° C between the sensors and the environment.
Allow at least 4 hours for the sensors to reach
ambient temperature before opening the box to
avoid condensation on the parts.
• Do not open the shipping box with a knife that will
deeply penetrate the box. The knife may damage
the sensors or sensor cables.
• Do not remove the sensing unit protective cap until
the sensor is ready for installation into the exhaust
system.
• Avoid impact to the NOx sensor, dropping the
sensor could cause permanent damage. If the
sensor has had an impact, discard the sensor.
• Do not paint any part of the sensing unit.
• Do not clean any part of the sensor with chemical
cleaners.

Typical example
1. Remove protective cap from sensor. Ensure that
the threads of NOx sensor have sufficient anti-
sieze compound applied. Install NOx sensor (1) to
the OEM tube assembly. Tighten the NOx sensor
to a torque of 50 ± 10 N·m (37 ± 7 lb ft).
2. Position clips (2) for the harness assembly.
3. If bolts and clips are required, install bolts to clips.
Tighten the bolts to a torque of 28 N·m (248 lb in).
