441-5127-03 A2C10474600-125B NOx sensor

441-5127-03 A2C10474600-125B exhaust NOx Nitrogen Oxide sensor

Continental NOx sensor position on CAT machine is at engine output.

441-5127-03 Nitrogen Oxide sensor is direct replacement to CAT (caterpillar) or continental brand part.

If you have did on-board computer scan after seeing check engline light on the dashboard and your machine shows any fault code from the list below, then it means nitrogen oxide sensor has failed.

There is no need to spend a fortune for original continental part at dealer shop, when replacement part will do a job.

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 Oxides.

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

441-5127-03 A2C10474600-125B sensor fits many different CAT machines.

Sensor is also kwown as control unit with nox-sensor for emissions control.

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.

Dealer will charge you over £500 for a single sensor.

You will find a list of the the most common error codes of nox sensor circuit faults.
