2015 ISX 15. Fault...

2015 ISX 15. Fault code SPN 3226 FMI 10. How far can I drive with this? Rough repair estimate?

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

2015 Volvo 780, Cummins ISX 15

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

I'm on the road currently and the code just came up as I was entering a customers facility. Not sure if I will do repair myself.

Hello and Welcome to Just Answer! Thank you for your question. I look forward to working with you to provide you the information you are seeking.It's just for the Outlet NOX sensor. At this time there is no effect on performance but it should be addressed ASAP and other faults may become active and derate you. You can replace the sensor yourself if you want. It takes like 5 min and the sensor can cost 2-3 hundred bucks.

Details for Cummins fault code: 3545

3226-10 Aftertreatment 1 Outlet NOx Sensor - Abnormal Rate of Change

Reason

Aftertreatment Outlet NOx Sensor Circuit - Abnormal Rate of Change. The aftertreatment outlet NOx sensor reading is not valid.

Effect

None on performance.

Component Location

The aftertreatment outlet NOx sensor location can vary, depending on engine application. It is usually located in the exhaust system at the outlet of the aftertreatment selective catalytic reduction (SCR) catalyst.

Circuit Description

The aftertreatment outlet NOx (mono-nitrogen oxides) sensor is a smart device that communicates with the engine control module (ECM) via the J1939 data link. The aftertreatment outlet NOx sensor performs its own internal diagnostics and reports malfunctions back to the primary ECM using the J1939 data link. The NOx sensor is permanently attached to the NOx control module. They are serviced as a single component and can not be replaced individually. The aftertreatment outlet NOx sensor is used to measure the NOx emissions at the outlet of the aftertreatreatment system.
