Frequently Asked Questions
Q: Will this sensor clear my active Cummins SCR/emissions fault codes?
A: Yes. Because this premium Dinex 2nd Generation smart sensor matches original factory calibration parameters and sensor software protocols, it will allow your vehicle's ECU to reset and clear active check engine lights or engine derate fault codes once the proper adaptation reset or drive cycle is completed.
Q: How do I verify this fits my specific truck?
A: Check the cross-reference list above for your stamped OEM number. If your old sensor matches 5295473, 4326873, or 2872948, this is the correct direct-fit replacement plug.
Important Fitment Note: Always verify correct fitment using your engine serial number (ESN) or complete OEM part number cross-reference before purchasing. Exhaust setup variations can exist within the same model year range. Pictures are for reference only.
