Frequently Asked Questions
This inlet NOx sensor is designed for selected heavy-duty commercial applications equipped with Detroit Diesel DD13 and DD15 engines.
- Freightliner: Cascadia with DD13 and DD15 engines, 2012–2022
- Western Star: Commercial models with DD13 and DD15 engines, 2016–2022
Always compare the OE part number on your original sensor with the numbers listed above or provide your VIN before purchasing to confirm exact compatibility.
A Nitrogen Oxide (NOx) sensor monitors nitrogen oxide levels within the vehicle's exhaust system. An inlet NOx sensor is positioned at the specified inlet location of the emissions system and supplies emissions data to the vehicle's control system.
- Emissions Monitoring: Measures NOx levels in the exhaust system
- SCR Management: Supports diesel emissions control operation
- Engine Management: Provides emissions-related data to the vehicle control system
A defective NOx sensor may cause different symptoms depending on the vehicle and emissions system configuration.
- Check engine or emissions warning light
- SCR or emissions system fault codes
- Reduced engine performance
- Incorrect or unstable emissions readings
- Increased fuel consumption
- Emissions system warnings
- Vehicle entering a reduced-power or protection mode
A qualified technician should diagnose the vehicle before replacing the sensor, as wiring, connectors and other emissions components can produce similar symptoms.
Professional installation by a qualified technician is strongly recommended.
- Electrical Connection: The 4-pin connector must be correctly connected
- Sensor Position: The sensor must be installed at the correct inlet position
- Exhaust Conditions: Correct installation is important due to high exhaust temperatures
- Diagnostic Testing: Fault codes and emissions readings should be checked after installation
- Warranty: Professional installation is required to validate the extended warranty
This NOx sensor uses a 4-pin electrical configuration. The specified pin arrangement is:
