Keep your truck's emissions system reading nitrogen oxide levels as designed with this Dorman sensor: the Dorman - HD Solutions Nitrogen Oxide (NOx) Sensor 904-6001, cataloged for the turbocharger outlet pipe position. It fits many trucks, among them the 2011-2012 Freightliner Cascadia, 2012 Freightliner Columbia and 2011-2012 Freightliner Coronado. See the Buyer's Guide tab for the full list of trucks and engines.

A NOx sensor measures nitrogen oxide in the exhaust stream and reports it to the truck's control system. Dorman made this sensor to match the original equipment sensor on certain vehicle years, makes and models. It is designed to bring nitrogen oxide detection back to proper working order and help the truck comply with emissions regulations.

  • Direct replacement: built to match the original sensor's function and performance on specified vehicles.
  • Proper NOx detection: intended to properly repair nitrogen oxide detection to help meet emissions regulations.
  • Application specific: reverse engineered from the original design for certain vehicle years, makes and models.
  • Trustworthy quality: supported by a U.S.-based team of engineers and quality specialists.

Specifications:

  • Package contents: one sensor with module
  • Fit type: specific fit
  • Wiring harness length: 920 mm
  • Wire gauge: 22
  • Connector: grey, rounded rectangle, female
  • Terminals: 4 male blade terminals
  • Country of origin: China

An illuminated emissions warning lamp or stored NOx sensor fault codes can be signs that this sensor may need replacing. Diagnose the cause before replacing it, because other faults can produce similar warnings.

Frequently Asked Questions

What does a NOx sensor do?

It reads nitrogen oxide levels in the exhaust and reports them to the truck's control system so the emissions system can monitor NOx. This sensor is cataloged for the turbocharger outlet pipe position.

What comes in the box with the 904-6001?

The box holds one NOx sensor with module. The harness is 920 mm long with 22-gauge wire and ends in a grey, rounded-rectangle female connector with 4 male blade terminals.

What trucks does this NOx sensor fit?

Popular applications include the 2011-2012 Freightliner Cascadia, 2012 Freightliner Columbia and 2011-2012 Freightliner Coronado. See the Buyer's Guide tab for every listed truck and engine.

What are signs a NOx sensor may need replacing?

An illuminated emissions warning lamp or stored NOx sensor fault codes are signs it may need replacing. Diagnose the cause first, because other faults can trigger similar warnings.

Is this a direct replacement for the original sensor?

Yes. Dorman reverse engineered it from the original design to match the original sensor's function and performance on specified vehicles, so it is a direct-fit replacement for the listed applications.
