How do you fix a faulty NOx sensor?

If you have run a diagnostic and determined that your car has a NOx sensor problem, you have two options: repairing the sensor or replacing the faulty sensor. A good quality sensor doesn’t come cheap, so you should try to fix the faulty sensor and only replace it if you have failed to repair it….

Find NOx Sensor Failure

Like any other car part, the NOx sensors also fail, and you have to fix or replace them to restore your car to proper working condition. Luckily, when the sensors fail, they give several symptoms that include: The engine warning lights come on. While the NOx sensor isn’t mounted on the engine bay, its failure…

What happens when NOx not work

when the NOx sensor not works, there are many errors display on the dashboard, the vehicle can’t work well, Nox sensor is part of SCR system, so you will find the SCR system fault as well. These faults include increased fuel consumption, unstable and erratic idle all these are signs that the Nox Sensor could…

Smart Nox Sensor

A High Failure Diesel Automotive Part Required for Emissions Regulations. Introduction Nox sensor, full name is Nitrogen Oxide Sensor, used to detect the level of nitrogen oxide being emitted by diesel vehicles, to ensure compliance with emissions regulations. Most engines feature two Nox sensors: an upstream and downstream sensor.  As strict Nox regulation, precise Nox…

Why Need Nox Sensor

The term Nox represents several forms of nitrogen oxides such as NO (nitric oxide), NO2 (nitrogen dioxide), and N2O (nitrous oxide, also known as laughing gas). In a gasoline engine, NO is the most common form of NOx at around 93%, while NO2 is around 5% and the rest is N2O. There are other forms of NOx such as N2O4 (the dimer of NO2), which only exists…

Nox Sensor Function

Automotive NOx sensors are primarily of the amperometric type, with two or three electrochemical cells in adjacent chambers. The first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. Commercial sensors, available from several suppliers, are used for the control of NOx…
