Did you know that at Cojali we test our NOx sensors?

December 11, 2025

Nowadays, NOx sensors are one of the most demanded parts in the aftermarket sector. Their relevance within the anti-pollution system, as a key element, is the best proof of this.

At Cojali Parts we have our own NOx sensors, designed entirely by our team, where we control every detail of the process.

One of our key differentiators is the ability to verify that each sensor meets the highest quality standards.

We achieve this thanks to our automatic verification bank.

Our engineering team has put all its know-how into the development of this tool, which is vital to ensure the reliability of the product. It allows us to:

• Check the analogue signals of the measuring probe.

• Simulate communication with the vehicle.

This way, our end-of-line test faithfully reproduces the operating conditions of a truck.

During the test, the sensor "thinks" that it is already installed in the vehicle!

In addition, this electronic bench allows us to program and update the software of the NOx sensors to the latest versions on the market, ensuring maximum compatibility.
