Figure 9.9 NOx Sensor Harness Clipping
Routing and clipping of the NOx sensor cable must not result in any of the
temperature limits stated in table 9.6 being exceeded. Under no
circumstances should the NOx sensor cable be tie wrapped to the sensor boy
as shown below as during operation the sensing unit will heat to temperatures
above 200DegC, which will cause damage to the sensor cable.
Installation Criteria
Max Temp Limits
Sensor to Controller Electrical Cable -40Deg to 200DegC
SEA Grommet (Rear of sensing element) -40Deg to 200DegC
SEA hex fitting -40Deg to 620DegC
Table 9.6 Sensing Unit Temperature Limits
• Harness bend radius
<20mm
• Sensor body will reach
temperatures above
200DegC

9.2.3.3 NOx Sensor Controller Electrical Connection
Electrical connection to the NOx sensor is made via a 6-way Ampseal
connector. The mating connector part numbers are shown in table 9.7.
