FITMENT
Compatible with DAF heavy-duty diesel vehicles equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

• DAF XF series trucks
• DAF CF series trucks
• DAF LF series trucks (selected SCR diesel configurations)
• Euro 5 / Euro 6 SCR aftertreatment systems depending on engine calibration

Using reference numbers:

• 1973528 (DAF OEM part number)
• 5WK96759B (Continental/VDO sensor family cross-reference)
• SCR NOx sensor system variant used in DAF emissions control systems

This sensor monitors NOx levels in the exhaust and supports accurate AdBlue dosing to meet emissions standards.

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) in the exhaust system and sends real-time data to the ECU to control AdBlue injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the SCR exhaust system, typically upstream or downstream of the catalytic converter depending on truck setup.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue warnings, NOx sensor fault codes, reduced engine power, or limp mode activation.

Q4: Is 1973528 interchangeable with other DAF sensors?
A4: It is part of a DAF SCR sensor family, but compatibility depends on engine type, ECU calibration, and emission system version.
