Better diesel engine performance with high-quality NOx Sensors.
The cleaner way to get your fleet back on the road. Our solution flush is trusted by over 100+ companies.
Cost savings
Aftermarket sensors often come at a lower price point than OEM sensors, allowing businesses to save on costs without sacrificing quality.
Availability
These sensors are typically available more readily, helping to minimize downtime and ensuring that vehicles remain operational.
Compatibility and Reliability
Many aftermarket sensors are rigorously tested for compatibility with various vehicle systems, ensuring effective operation.
Performance in Harsh Conditions
Aftermarket NOx sensors can perform reliably under extreme conditions, such as cold weather, reducing the likelihood of sensor failures during critical times.

Frequently asked questions
Everything you need to know about the solution flush.
Why should I replace my sensor?
Sensors can fail due to wear and tear over time, leading to increased fuel consumption, excessive DEF usage, and reduced engine power.
What does a NOx sensor detect?
The NOx sensor detects nitrogen oxides in the exhaust gas. This is important for engines with urea-based SCR systems. The sensor helps regulate the amount of urea injected into the exhaust stream, reducing emissions and keeping the engine compliant with environmental standards.
What can cause a NOx sensor to fail?
Several factors can lead to NOx sensor failure, including:
Soot Buildup: soot from the combustion process can cover the sensor, reducing its accuracy. Over time, abrasive soot particles can damage the sensor itself.
Water Intrusion: water in the sensor’s wiring or ECU can lead to malfunction.
Physical Damage: any damage to the sensor or its wiring can render it ineffective.
How many NOx sensors are there in a diesel engine?
Typically, diesel engines feature two NOx sensors—one located upstream of the SCR catalyst and one downstream. These sensors work together to measure and regulate NOx emissions effectively.
How do I know which NOx sensor is faulty?
To identify a faulty NOx sensor, you can use a multimeter to check the voltage. If the voltage doesn’t match the manufacturer’s specifications, the sensor may be malfunctioning. Diagnostic tools can also help pinpoint which sensor—upstream or downstream—is causing the issue by reading specific error codes.
Can you clean a diesel NOx sensor?
NOx sensors are self-cleaning to some extent, so manual cleaning is not recommended. If the sensor is malfunctioning, it’s best to replace it. Attempting to clean it may cause further damage and won’t necessarily resolve the issue.
