FITMENT
Compatible with DAF heavy-duty trucks equipped with PACCAR MX13 Euro 6 SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

• DAF XF / CF / LF series (MX13 engine platforms)
• PACCAR MX13 diesel engines (Euro 6 emissions systems)
  Using reference:
• SNS0159E
• 2236409
• A3C04720000-01 / A3C04720000-01-01

This is an exhaust aftertreatment NOx sensor (outlet type commonly used on SCR systems).

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

Q2: Where is it installed?
A2: It is installed on the SCR exhaust aftertreatment system, typically upstream or downstream of the SCR catalyst depending on configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, NOx sensor fault codes, reduced engine performance, or engine derating (limp mode).

Q4: Is SNS0159E interchangeable with 2236409?
A4: Yes, SNS0159E is a Continental/Bosch-type designation and 2236409 is the DAF OEM reference used for the same SCR NOx sensor system.
