Walker Products 1004-1043 nitrogen oxide (nox) sensor for the 2016-2024 Peterbilt 579 and other vehicles reads the nitrogen oxide level in the exhaust gas.
- Reports exhaust NOx readings to the engine's control system
- Installs at the SCR catalyst inlet position
Quick facts
- Part: Walker Products 1004-1043 nitrogen oxide (nox) sensor
- Fits: the 2016-2024 Peterbilt 579 and other vehicles
- Position: SCR catalyst inlet
A failing NOx sensor can show up as an emissions warning light or a stored fault code. With the engine off and cool, look over the sensor's connector and wiring for damage, corrosion or a loose fit. A shop can read the codes and test the sensor, since a wiring fault can look much like a failed sensor.
Fits
This NOx sensor also fits the 2016-2024 Kenworth T680 and the 2016-2024 Kenworth T880 6-cylinder 10.8L, 11.9L, 12.9L or 14.9L and the 2017-2024 T880 6-cylinder 8.9L. If your truck is not named here, look up its year and engine in the "Vehicles it fits" section. This listing is one sensor, and these trucks take one.

Frequently Asked Questions
Does the Walker Products 1004-1043 NOx sensor fit a 2016-2024 Peterbilt 579?
Yes. Walker Products 1004-1043 fits the 2016-2024 Peterbilt 579, and it installs at the SCR catalyst inlet.
Which position does this nitrogen oxide sensor go in?
This sensor is for the SCR catalyst inlet position. It reads the nitrogen oxide level in the exhaust gas at that point.
Can a bad NOx sensor be behind an emissions warning light?
Yes, a failing NOx sensor can be one reason for an emissions warning light or fault code. Because it sits in the exhaust, have a shop test it rather than probing it yourself.
Is Walker Products 1004-1043 the right NOx sensor for a 2016-2024 Kenworth T680?
Yes. Walker Products 1004-1043 fits the 2016-2024 Kenworth T680. For another truck, look in the "Vehicles it fits" section.
Is this Walker Products 1004-1043 listing a single NOx sensor?
Yes. This Walker Products 1004-1043 listing is one sensor, and the trucks it fits take one.
