Table 9.8 NOx Sensor Mating Connector Terminal Assignment
It is the customers responsibility to connect the two NOx sensors to the
engine ECM J1 connector as part of the machine harness. Connection of
these sensors to the ECM must be made as shown in figure 9.12.

9.3 Ammonia (NH3)Sensor
9.3.1 Ammonia (NH3) Sensor Operation
The 1204F DOC+SCR solution requires an Ammonia sensor to directly
measure the ammonia levels within the tailpipe out exhaust emissions. The
Ammonia sensor must be mounted in the exhaust pipe work post the SCR
catalyst. The Ammonia sensor is used to ensure excess ammonia is not
being injected into the exhaust gas flow and to provide information for dosing
adjustments to be made if necessary.
