DZ112080 DZ109690 RE553440 NOx Sensor Cross References

Fitment Verification: Match the OEM or manufacturer number stamped on the original NOx sensor or control module to one of the cross-reference numbers below before ordering.

Outlet NOx Sensor with 24-Inch / 615 mm Wire Harness

The wire harness length is especially important on this John Deere application. Skyline SNXJ02 is the outlet / downstream NOx sensor with a 24-inch / 615 mm harness.

John Deere service information identifies DZ109690 as a 12-volt NOx sensor with a 615 mm lead. It replaced RE553440 in compatible applications, and DZ112080 is the later John Deere replacement for DZ109690.

Do not select a John Deere NOx sensor based only on connector appearance. Other John Deere NOx sensor families can use different lead lengths and inlet / outlet positions. Always compare the stamped OEM number, sensor position and harness length before ordering.

Plain White Box on the Outside. OEM on the Inside.

Skyline SNX Series NOx sensors are OEM designed and manufactured by an original-equipment sensor supplier. Skyline SNXJ02 is engineered to provide the construction, electronics and application-specific performance expected from an original-equipment replacement.
