What is a NOx Sensor?

The smart Nitrogen Oxide Sensor (NOx) is built to detect high levels of nitrogen oxides within the exhaust emissions of a vehicle. The sensor feeds back intelligence to the ECU of the system, this includes the NOx level measurements during a duty cycle. If the guideline parameters are not met an emissions light will appear on the vehicles instrument cluster, forcing operators to investigate and take action.

Why do NOx sensors fail?

There are a few reasons behind sensor failures, however the main reason is the condition of the vehicles engine. Regular servicing is paramount for ensuring the carbon output is as low as possible. Low carbon output reduces the likelihood of premature sensor failures due to carbon clogging of the sensor probe.

What is the benefit of regular servicing?

Regular maintenance servicing such as oil changes and valve clearance are key to ensuring longevity.

If I run my vehicle with an emissions failure what is likely to happen?

Running vehicles with emissions failures will cause unwanted attention from local authorities, therfore it is key to resolve the issues as quickly as possible and avoid prosecution.
