55512347 SNS0427A A3C02960600-01 NOX exhaust gas sensor

Nitrogen Oxide sensor is factory fitted on GM brand Opel and Vauxhall cars.

If you have did on-board computer scan after seeing check engline light on the dashboard and your car is showing any of these error codes P11DC P11DB P229F62 P229F P2202 P2201 P2203 U029E00 U029E U029D00 U029D, it means that NOX sensor has failed.

It is always recommended to fix this issue as soon as possible to avoid any damages to DPF filter, otherwise diesel particulate matter or soot can clog filter and it will cost you thousands to fix.

NOX stands for Nitrogen Oxide.

Error cleaning may be required, but just once after fitting new NOX sensor, it can be done by yourself, no need to visit dealer.

Information from sensor: ASM-NOXPOSN1.

Continental SNS0427A A3C02960600-01 sensor is also kwown as control unit with nox-sensor for emissions control.

55512347 NOX sensor is factory fitted to Vauxhall or Opel cars with diesel engine.

DPF means diesel particulate filter.

What does nox sensor do ?

A nitrogen oxide sensor in short NOX is high temperature part is used in cars to detect and measure out amount of this compound (nitrogen oxides) coming out of exhaust system to ensure, it is mostly found in diesel cars.

Replacement sensor probe with ballast unit will save you a fortune, solve your NOX problems and you will comply with enviromental emissions laws again.
