Nox Sensors

Browse NOx sensor listings for diesel truck applications and compare the complete part number before ordering. The sensor position, vehicle configuration and emissions system matter. A listing for the same engine family or truck brand does not by itself establish that a sensor will work in your vehicle.

Part selection, fitment and ordering guidance

Match the sensor position and connection

Send the VIN or engine serial number, the number from the existing sensor and whether it is identified as an inlet or outlet sensor in the service information. Compare the connector, cable arrangement and any included control module shown in the listing. Ask ATP to check a superseded or cross-reference number before selecting an alternative.

Use the vehicle manufacturer's diagnostic procedure; an emissions fault does not prove that the NOx sensor itself has failed.
Confirm the exact sale item, condition and included components in the product description.
Have the installer confirm whether the vehicle requires a reset, setup or other service procedure after replacement.

Check the listing for new, used or remanufactured condition and current availability. ATP is an independent reseller, not an authorized manufacturer dealer. ATP warranty terms and return eligibility apply; manufacturer coverage is not assumed.
