This is a GM Genuine Parts component — the same part GM specifies as the factory replacement for the original equipment sensor, not an aftermarket copy. Position 2 — What That Means Position 2 is the DOWNSTREAM (rear) sensor. It sits after the selective catalytic reduction (SCR) catalyst and measures the NOx level leaving the aftertreatment system, which the ECM uses to confirm the SCR is working and to trim diesel exhaust fluid (DEF) dosing. It is not the upstream/inlet sensor (Position 1), which sits ahead of the SCR. Ordering the wrong position is the most common mistake on this part — please confirm which sensor your fault code points to before buying. Vehicle Fitment 2014–2015 Chevrolet Cruze, 2.0L turbo-diesel (LT / LTZ 4-door sedan) This part is engine-specific to the 2.0L diesel Cruze. It does not fit the gasoline Cruze, and it is not the Duramax truck NOx sensor. Please verify your part number against the sensor you are replacing before purchase.
