APPLICATIONS

The A045S167 Cummins Nitrogen Oxide Sensor is intended for compatible exhaust emissions monitoring and aftertreatment systems. Specific vehicle models, engine types, and system configurations have not been confirmed. Verify the part number against the original equipment before ordering.

FUNCTION

The Nitrogen Oxide Sensor measures NOx concentrations in exhaust gases and sends readings to the vehicle’s emissions control system. These measurements help monitor emissions levels and support proper aftertreatment system operation.

A worn, damaged, or failing Nitrogen Oxide Sensor may cause symptoms such as:

• Check engine light or emissions warning indicators
• NOx sensor-related diagnostic trouble codes
• Inaccurate exhaust emissions readings
• Aftertreatment system performance issues
• Failed emissions testing, where applicable
• Reduced engine performance or limited-power operation on some vehicles

WHY REPLACE A NITROGEN OXIDE SENSOR?

A faulty NOx sensor may provide inaccurate readings and interfere with emissions system monitoring. Replacing a defective A045S167 Cummins Nitrogen Oxide Sensor with the correct compatible part can help restore accurate NOx measurement and support proper aftertreatment operation. Additional diagnosis may be required to determine whether the sensor is the cause of the problem.

FITMENT INFORMATION

Before purchasing the A045S167 Nitrogen Oxide Sensor, verify the part number, VIN, vehicle model, engine, and exhaust aftertreatment configuration. Confirm that the replacement matches the original equipment and connector specifications. Specific fitment applications have not been independently confirmed.
