A034M373 | Genuine OEM Cummins Nitrogen Oxide Sensor

A034M373 is a Genuine OEM Cummins Nitrogen Oxide Sensor designed to monitor nitrogen oxide (NOx) levels in the exhaust system. The sensor provides NOx measurement data used by the emissions control system to monitor and manage exhaust emissions.

PRODUCT INFORMATION

Part Number: A034M373
Brand: Cummins
Condition: Genuine OEM
Component: Nitrogen Oxide Sensor
Fuel Type: Diesel
Engine Applications: Verify by Part Number and VIN
Other important specifications: NOx sensor for exhaust emissions monitoring

APPLICATIONS

The A034M373 Nitrogen Oxide Sensor is used in diesel engine exhaust emissions monitoring systems. Specific vehicle, engine, and system applications should be verified using the original part number and VIN before purchase.

FUNCTION

The A034M373 Nitrogen Oxide Sensor measures nitrogen oxide levels in the exhaust and sends information to the engine and emissions control system. This data helps the system monitor exhaust emissions and support proper emissions control operation.

A worn, damaged, or failing Nitrogen Oxide Sensor may cause symptoms such as:
• Check engine or emissions warning light
• NOx sensor-related fault codes
• Incorrect or inconsistent NOx readings
• Reduced emissions system performance
• Emissions-related diagnostic faults
• Possible reduced engine performance or altered system operation

WHY REPLACE A NITROGEN OXIDE SENSOR?

A faulty Nitrogen Oxide Sensor can provide inaccurate exhaust emissions data and may trigger emissions-related diagnostic faults. Replacing a defective sensor with the correct A034M373 Genuine OEM Cummins part can help restore accurate NOx monitoring and proper emissions system operation.

FITMENT INFORMATION

Before purchasing, verify the Part Number, VIN, vehicle model, engine, and configuration to confirm compatibility. Do not rely on appearance alone, as NOx sensors may vary by application and emissions system.

If you are unsure whether this part is correct for your vehicle, please contact us with your VIN and original part number. We are happy to help verify compatibility before purchase.
