Plain White Box on the Outside. OEM on the Inside.
Skyline SNX Series NOx sensors are OEM manufactured, meaning they are produced by the same manufacturer that supplies original-equipment NOx sensors.
Plain white box on the outside. OEM on the inside.
Instead of paying extra for OEM-branded packaging, you receive an OEM-manufactured sensor in Skyline packaging. The sensor delivers the construction, calibration and fit expected from original equipment while providing OEM quality at an aftermarket price.
A0101532128 Detroit Inlet NOx Sensor Position
Skyline SNX109 is the inlet / upstream NOx sensor. It is positioned ahead of the primary aftertreatment components and is used to measure engine-out NOx levels before exhaust gases pass through the downstream emissions-control system.
This position is important because Detroit applications may use more than one NOx sensor. An outlet or downstream sensor with a similar connector or module appearance is not necessarily interchangeable with this inlet sensor.
Always verify the original stamped OEM number and confirm that the sensor being replaced is the inlet / upstream unit before ordering.
Detroit 1-Box and Split-Canister Aftertreatment Applications
This NOx sensor family is used on compatible Detroit aftertreatment configurations where the original inlet sensor carries A0101532128, A0081530828, A0091530328 or a related verified cross-reference.
Applications may include Detroit 1-Box integrated aftertreatment systems as well as compatible earlier split-canister / 2-Box configurations. Because Detroit system architecture varies by model year, chassis and emissions calibration, the stamped OEM sensor number should be used as the primary fitment check.
A0101532128 NOx Sensor Engine Applications
Compatible Detroit Diesel engine applications may include:
- Detroit DD13 – 12.8L
- Detroit DD15 – 14.8L
- Detroit DD16 – 15.6L
The highest-priority OEM search references for this Skyline SNX109 are A0101532128, A0081530828 and A0091530328.
