FITMENT:
Compatible with Iveco heavy-duty trucks equipped with SCR (AdBlue/DEF) Euro 6 systems, including:

• Iveco Stralis II (Euro 6)
• Iveco Trakker II
• Iveco X-Way (Euro 6 / Euro 6 Step E)
• Some Iveco S-Way early SCR configurations (platform dependent)

OEM / Cross reference numbers:

• 5801627702
• 5801777219
• 5801429373
• 5WK96720A / 5WK9 6720A
• 5801618980 (related supersession in some catalogs)

FUNCTION:

• Measures nitrogen oxide (NOx) concentration in diesel exhaust
• Sends real-time data to ECU via CAN (J1939 communication)
• Controls AdBlue (DEF) injection for SCR efficiency
• Monitors catalyst performance and emissions compliance
• Prevents engine derate and SCR system faults

INSTALLATION POSITION:

• SCR inlet or outlet NOx sensor (vehicle-dependent configuration)
• Mounted on exhaust line before or after SCR catalyst
• Commonly used in Euro 6 aftertreatment systems

IMPORTANT NOTE:
Iveco NOx sensors like 5WK96720A are part of a shared SCR sensor platform, meaning:

• Same sensor design used across Stralis / Trakker / X-Way
• Inlet and outlet sensors are NOT interchangeable
• Harness length and calibration vary by position and engine setup
• ECU determines correct function (position-specific coding required)

Incorrect selection may cause SCR faults, AdBlue errors, or limp mode.

FAQ:

Q1: What vehicles does it fit?
A1: Iveco Stralis II, Trakker II, and X-Way Euro 6 trucks.

Q2: Is this inlet or outlet sensor?
A2: It can be used as inlet or outlet depending on SCR system configuration.

Q3: What are failure symptoms?
