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

• Tractor Series: 8295R, 8320R, 8345R, 9360R, 9410R, 9460R, 9510R
• Combine Series: S660, S670
• Also fits related 7R / 8R platform SCR-equipped models (depending on engine/emissions setup)

OEM / Cross reference numbers:

• RE552182 / RE575061 (related Deere NOx sensor family)
• DZ112080 (updated OEM platform reference)
• 5WK96773 / 5WK9 6773 (Continental sensor platform equivalent)
• RE553440 (related SCR NOx sensor family variant)

FUNCTION:

• Measures nitrogen oxide (NOx) levels in diesel exhaust
• Sends real-time emissions data to ECU via CAN/J1939 communication
• Controls AdBlue (DEF) dosing in SCR system
• Monitors catalyst efficiency and emissions performance
• Ensures Tier 4 Final / Stage IV emissions compliance
• Prevents engine derate and SCR system faults

INSTALLATION POSITION:

• SCR inlet or outlet NOx sensor (system dependent)
• Mounted on exhaust line before or after SCR catalyst
• Works in dual-sensor configuration (upstream + downstream)

IMPORTANT NOTE:
John Deere NOx sensors in this range are part of a universal SCR sensor platform, meaning:

• Same sensor design used across tractors and combines
• Inlet and outlet sensors are NOT interchangeable
• ECU software determines correct sensor position
• Calibration differs depending on engine and emissions system

Incorrect installation may cause SCR faults, AdBlue errors, or engine derate.

FAQ:

Q1: What machines does it fit?
A1: John Deere 8295R–9510R tractors and S660/S670 combines with SCR systems.

Q2: Is it inlet or outlet sensor?
A2: It can be inlet or outlet depending on SCR configuration.

Q3: Are RE552182 and DZ112080 the same?
A3: DZ112080 is an updated OEM reference within the same NOx sensor platform family.

Q4: What are failure symptoms?
A4: SCR warning light, NOx sensor fault codes, AdBlue system errors, engine derate.

Q5: Does installation require programming?
A5: Some John Deere machines require SCR reset or ECU adaptation after replacement.
