6/30/23, 1:50 PM Article Volvo NOx Sensor Troubleshooting Guide US10+OBD13 And Newer Emissions Component Overview There are two Nitrogen Oxide (NOx) sensors in the Exhaust Aftertreatment System, an INLET and OUTLET. They are smart sensors reporting on the DL7 (J1939-7) data link and they measure the INLET (Pre SCR) and OUTLET (Post SCR) of NOx. The NOx sensors have unique CAN identification numbers and cannot be swapped. Additionally these sensors are not operational until the exhaust is up to operating temperature and free of moisture. The Engine Control Module compares the INLET and OUTLET NOx readings to evaluate the efficiency of the SCR. The primary failure mode the NOx Sensors is internal failure, which will generate a sensor specific fault code. https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!PS1__TABTHREAD3?pyActivity=%4… 1/6 6/30/23, 1:50 PM Article Diagnosis and Repair Review the tables below to determine which category the Fault Code currently being diagnosed falls under. Proceed according to the instructions for the appropriate section. INLET NOx Sensor (NOx1) Diagnostic Trouble Codes - Sensor Failure REPLACE the sensor if any codes in red below are active and/or confirmed. Do not replace for inactive codes.

Do NOT Cut the sensor wiring harness, all NOx sensors are currently on mandatory return. Inlet NOx Sensor (NOx1) Diagnostic Trouble Codes Potential Sensor Failure These codes in yellow below indicate that the inlet NOx sensor is potentially damaged, but further investigation is required to verify sensor condition.

If the NOx sensor has been replaced within past 3 months open an E-Service Case. Repair: • If the INLET (NOx1) sensor fails the evaluation, replace the Inlet NOx Sensor ONLY. • If the NOx2 sensor (Outlet NOx Sensor) fails the test, disregard the results. OUTLET NOx Sensor (NOx2) Diagnostic Trouble Codes - Sensor Failure REPLACE the sensor if any codes in red table below are active and/or confirmed. Do not replace for inactive codes.

If NOx sensor has been replaced within past 3 months open an E-Service Case. Repair: • If the Outlet (NOx2) sensor fails the evaluation, replace the Outlet NOx Sensor ONLY. • If the NOx1 sensor (Inlet NOx Sensor) fails the test, disregard the results. Diagnostic Trouble Codes With "NOx Sensor" in the Description Direction/Repair: DO NOT REPLACE the NOx sensor(s) for these codes. Diagnostics should be performed using PTT Diagnostics and the comment section in the table below.

The table above specifies the likely cause of each code. Rules for Replacement Warranty will only cover replacement of the NOx Sensors if one of the codes in Red or Yellow listed above is active or confirmed. If the NOx Sensor is suspected to have failed with no active or confirmed codes, an eService case is required for further evaluation. Standard Diagnostic Time for a NOx Sensor is 1.0 hr.
