8/21/2013 · The ‘sensor’ includes an approx. 25 harness to a square metal piece that bolts to the truck and has the connector to mate to the truck harness. Presumably there is a small circuit board in the metal piece. The block for the sensor at the back/top of the motor is on the LHS of the firewall. The block for the DPF sensor is frame mounted.
12/31/2019 · During a cold start, moisture in the exhaust system can interfere with NOx sensor operation. In this scenario, the Duramax ECM will not turn on the NOx sensor heaters until exhaust temperatures reach a certain threshold and condensed moisture is evaporated. This can result in a delay of up to 5 minutes before both NOx sensors are fully operational.

NAPA Echlin NOx sensors monitor the level of nitrogen oxide being emitted by a diesel vehicle to ensure compliance with emissions regulations.
7/1/2020 · The second NOx sensor is located between the Selective Catalytic Reduction (SCR) and the Diesel Particulate Filter (DPF) and monitors NOx levels downstream of the SCR. The second NOx sensor also provides the Engine Control Module ( ECM ) with information on the exhaust oxygen level during DPF regeneration.
