The Role of NOx Sensor (For CHRYSLER)
The SCR system uses NOx sensors to measure nitrous oxide levels in the air moving through the fuel system. This is a special type of high-temperature sensor that’s designed to target NOx.
The sensors come with a set threshold for NOx emissions. If the air passes this threshold, the SCR system will release a liquid-reductant agent through a catalyst into the exhaust system. The reductant is what’s known as a Diesel Exhaust Fluid (DEF), usually urea. This sets off a chemical reaction in the combustion chamber, which breaks down the NOx into O2, H2O and CO2, which is then released through the tailpipe.
The sensors are also designed to make sure the vehicle’s SCR system is working properly. There are usually two NOx sensors, one positioned upstream of the SCR catalyst and one downstream. The upstream sensor measures how much NOx is coming out of the engine so the SCR system can inject the right amount of DEF. The downstream sensor measures how well the SCR catalyst is performing.
Common symptoms of a faulty NOx sensor that affect cars’ performance include:
● Engine warning light. The check engine light going on is a sure sign that something needs to be addressed. It can occur when an electronics component fails – such as the NOx sensor.
● Engine limp mode or non-start status. The vehicle may enter ‘limp mode’ during a journey, triggered by the on-board computer, or the engine may not start.
● Increased NOx emissions. Without the sensor able to detect any issues, the vehicle may increase emission of oxides of nitrogen.
