Nitrogen Oxide (NOx) Sensor Repair

What is a NOx sensor?

The NOx sensor measures the amount of nitrogen oxide that is discharged by a diesel vehicle to ensure that it conforms to specified emissions regulations.

What happens if a NOx sensor fails?

It’s fairly common to have to replace your vehicle’s NOx sensor at some point in its lifetime as it is affected by wear and tear the same as most vehicle components. While some components can continue to work even when they’re a bit worn down, it’s important to replace your NOx sensor if it fails.

Signs of a failed NOx sensor that you should look out for are:

• The engine warning light coming on in the dashboard
• You’re using more fuel than normal
• Your car goes into limp mode
• You find that the power, acceleration and overall performance is reduced

Can I drive my car if the NOx sensor has failed?

You might be able to drive for a short time with a faulty NOx sensor but to be safe and to avoid potentially complex and costly repairs, get in touch with a reliable mechanic such as SW Motor Services.

Can a NOx sensor be repaired?

While NOx sensors can be repaired, this can be a costly business depending on how serious the fault is. It’s often more cost-effective to replace it with a good-quality refurbished sensor which can work just as well as a brand-new one.
