Finding Truck Sensors and Modules by Exact Application

Find ECMs, NOx sensors and aftertreatment components using the vehicle and engine configuration, not a universal model-name location chart.

Identify the configuration

• Vehicle make/model/year and VIN.
• Engine model, serial number and emissions generation.
• Aftertreatment assembly identification where available.
• The complete fault and reporting controller.
• A photo showing vehicle orientation and the component or connector.

Use position names carefully

Inlet and outlet NOx describe a relationship to the aftertreatment system; they do not identify one universal side of the chassis. The inlet and outlet guides separate the parameters. Exhaust routing and component packaging must be checked on the actual truck.

An example of configuration-specific evidence

Navistar’s cited water-shield bulletin addresses listed N13/N9/N10 vertical-exhaust applications and build dates. That restriction is why a useful location reference should include the configuration and source instead of transferring a photo from another truck. Navistar IK0700087 (November 2015)

Verify before disconnecting or ordering

Match the service diagram, component identification and connector details. Follow the relevant access and isolation procedure. Do not order a part solely because it resembles a photo or because the fault description includes a sensor name.

Prepare useful photos for remote help

Provide a wide orientation view, the component label and a clear connector view when safely accessible. Explain what has already been moved or replaced. Torque Edge can review the identification with you; exact location and physical work still depend on the vehicle configuration.

Sources and scope

References describe the applications and editions named in each document. For work on a truck, select current service information by engine serial number, reporting controller and calibration. A general guide does not replace those procedures.
