FITMENT:
Compatible with John Deere agricultural and construction equipment equipped with SCR (AdBlue/DEF) emission systems, including:

• John Deere 5085M
• John Deere 5100M
• John Deere 5115M
• Selected 5M / 6M / 7M series tractors
• Other Deere SCR-equipped agricultural machines (model-dependent)

OEM / Cross reference numbers:

• RE552182
• RE575061 (related supersession in some catalogs)
• 5WK96773 / 5WK9 6773
• 5WK97373 (platform-related variant reference in some listings)

This NOx sensor is used in the SCR exhaust aftertreatment system, measuring nitrogen oxide levels in diesel exhaust and controlling AdBlue dosing for emissions compliance.

FUNCTION:

• Measures NOx concentration in exhaust gas
• Sends data to ECU via CAN communication
• Controls SCR/AdBlue injection system
• Monitors catalyst efficiency and emissions performance
• Ensures Tier 4 / Stage V emissions compliance

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (depending on tractor configuration)
• Mounted on exhaust line between DPF and SCR catalyst or downstream SCR section

IMPORTANT NOTE:
John Deere NOx sensors like RE552182 belong to a shared agricultural SCR sensor platform, meaning:

• Same sensor may be used across multiple tractor models
• Inlet and outlet sensors are NOT interchangeable
• ECU calibration and wiring determine correct function
  Always confirm OEM number or VIN before ordering.
