What a NOx Sensor Does
A nitrogen oxide (NOx) sensor measures the amount of NOx gases in the exhaust stream. This data is sent to the vehicle’s emissions control modules so the system can properly adjust DEF dosing and manage the SCR system to reduce emissions.
Where NOx Sensors Are Used
- Selective Catalytic Reduction (SCR) systems
- Diesel particulate filter (DPF) aftertreatment systems
- Modern heavy-duty diesel truck emissions systems
Common Engines Using NOx Sensors
- Cummins ISX, X15 and ISB 6.7 engines
- Detroit Diesel DD13, DD15 and DD16 engines
- Paccar MX-13 and MX-11 engines
- Volvo D11, D13 and D16 engines
- Mack MP7, MP8 and MP10 engines
- International A26 engines
- Hino J08 and A09 engines
Common Signs of NOx Sensor Failure
- SCR system fault codes
- Emissions warning lights
- Incorrect DEF dosing
- Engine derate conditions
- Poor emissions system performance
Verify Fitment Before Ordering
NOx sensors vary by engine platform and emissions system design. To confirm compatibility provide:
- Engine serial number
