NOx Sensor Repair

What is a NOx sensor?

NOx sensors in cars monitor the levels of nitrogen oxides (NOx) in the exhaust gases. These gases are harmful pollutants that are produced during combustion, especially at high temperatures. NOx sensors are essential in modern vehicles, particularly those with diesel engines because they help make sure that your vehicle complies with emission standards.

How does a NOx sensor work?

The NOx sensor works by measuring the NOx levels and sending the data to the car’s computer, which adjusts the engine’s air-fuel mixture or activates systems like selective catalytic reduction (SCR) to reduce emissions.

What are common NOx sensor problems?

Common problems with NOx sensors include:

• Contamination from soot or unburned fuel
• Electrical faults
• Software issues

What happens if the NOx sensor fails or is faulty?

If the NOx sensor in your vehicle fails, it can prevent the engine from operating efficiently and you might notice that your vehicle is using more fuel than usual or that it isn’t performing as well.  The main issue is that emissions may increase and that is one of the reasons for a vehicle failing its MOT test.

The best way to avoid any issues with the NOx sensor is to bring your vehicle into Mill Road Motors for regular maintenance at our workshop in Christchurch so that we can help to keep the sensor working correctly and keep your vehicle performing as it should.

At Mill Road Motors, our affiliations with respected organisations like the RMI, IGA, The Motor Ombudsman and 1 TEC Auto Hub ensure we deliver services of the highest standard, staying up-to-date with the latest automotive technologies.
