FAQ

Q1: Are 5WK97439 and SNS436A the same sensor?
A1: Yes. 5WK97439 is the Continental NOx sensor reference, and SNS436A is the same sensor family used in Hyundai/Kia SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Hyundai and Kia diesel SUVs such as Santa Fe, Sorento, Tucson, and Sportage equipped with Euro 5 / Euro 6 SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream or downstream NOx sensor depending on exhaust system layout and ECU calibration.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends data to the ECU, which controls AdBlue dosing to reduce emissions and maintain SCR efficiency.
