Detroit Diesel Outlet NOx Sensor (PN: A101538128)

Item Name:
Detroit Diesel Outlet NOx Sensor (PN: A101538128)

Function:
The Outlet NOx Sensor (A101538128) measures the nitrogen oxide levels leaving the SCR catalyst. It acts as the "final check" for the emissions system, confirming that the DEF fluid is working effectively.

Compatibility:
Genuine Detroit Diesel part for DD13, DD15, and DD16 engines. Specifically for the "Outlet" or "Downstream" position.

Materials And Construction:
Smart sensor with an integrated control module. The probe is made of high-temp ceramic and stainless steel to survive the exhaust stream.

Installation And Maintenance:
Screws into the exhaust tailpipe area. The module bolts to the frame. Do not use anti-seize on the sensor threads as it can foul the element.

Performance:
Accurate reporting prevents engine derates. If this sensor reads too high (or fails), the truck will assume the emissions system is broken and limit speed.

• Genuine Detroit Diesel Part (A101538128).
• Outlet / Downstream position.
• Monitors SCR efficiency.
• Prevents emission derates.

Keep your Freightliner running smoothly with this Genuine Detroit NOx Sensor.
