NOx Sensor Routing The NOx sensor requires unique routing considerations. The NOx sensor harness must not be bundled with other wiring harnesses. However, it may be routed with other harnesses as long as they are not high voltage cables. The sensor harness is a set length and no altering or modifying of the NOx sensor harness is allowed.
