A0101532128 Detroit Inlet NOx Sensor Position

Skyline SNX109 is the inlet / upstream NOx sensor. It is positioned ahead of the primary aftertreatment components and measures engine-out NOx levels before exhaust gases pass through the downstream emissions-control system.

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.

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, use the stamped OEM sensor number as the primary fitment check.

Fitment Verification

Detroit aftertreatment systems can use multiple NOx sensors with different inlet and outlet positions. Fitment can also vary by engine, chassis, model year, emissions calibration, connector and harness configuration. Always verify the exact OEM number stamped on the original sensor and confirm that the sensor being replaced is the inlet / upstream unit.
