2016 Volvo D13 NOx Code Bank 1 Sensor 2 Explained

The 2016 Volvo D13 engine can experience issues related to the NOx code Bank 1 Sensor 2. This code relates to the downstream NOx sensor positioned after the selective catalytic reduction (SCR) catalyst. Its role is to monitor nitrogen oxide (NOx) levels in the exhaust system to maintain emissions compliance.

Common problems with D13 engines include NOx sensor failures and faults in the exhaust gas recirculation (EGR) system. Specifically, the Bank 1 Sensor 2 code can stem from various causes such as contamination of the sensor, wiring problems, or decreased efficiency of the SCR catalyst.

Troubleshooting steps should focus on inspecting the sensor wiring and connectors for any damage. If the sensor is faulty, cleaning or replacing it can resolve the issue. It is also important to verify that the SCR system is functioning properly. Maintaining the exhaust aftertreatment system regularly can help prevent the occurrence of these errors.

• Inspect NOx sensor wiring and connectors for damage
• Clean or replace the NOx sensor if needed
• Verify operation of the SCR system
• Maintain the exhaust aftertreatment system regularly
