Does BG 201139 replace OE 2296801?

Yes. BG 201139 is listed against 2296801 and 5WK9 6695C. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 201139 fit?

Recorded coverage includes IVECO. It is supplied as a direct-fit aftermarket nox sensors on 24V systems. Adaptation, reset or relearn procedures required by the vehicle manufacturer still apply after installation.

Does this fault code always mean the nox sensors has failed?

No. Exhaust leaks, wiring and connector damage, reductant quality, dosing performance and upstream engine faults can all produce the same codes. Validate those inputs before replacing BG 201139.

Product Description

This BG NOx (nitrogen oxide) sensor is designed for the urea/AdBlue-based SCR (Selective Catalytic Reduction) emissions system on IVECO Stralis / EuroCargo Euro 6. It is a direct-fit replacement for OE reference 2296801 / cross reference 5WK9 6695C. Rated for 24V electrical systems. The sensor provides accurate real-time NOx measurement for precise urea dosing control, helping maintain stable SCR performance and compliance with diesel emission standards.

Vehicle manufacturer names, logos and OE reference numbers are used for identification and compatibility purposes only. BEST GROWTH products are independent aftermarket products and are not manufactured, sponsored or endorsed by the respective vehicle manufacturers.

BG 201139 (OE 2296801): function on the vehicle

NOx Sensor 2296801 is supplied by BEST GROWTH under part number 201139, cross-referenced to OE 2296801, as a direct-fit aftermarket nox sensors. In service it acts as the closed-loop feedback element of the SCR circuit: it tells the controller how much NOx is still leaving the catalyst, so dosing is trimmed up or down instead of running to a fixed map.

BG 201139 is built to the position defined by its OE application on a 24V electrical system in truck service on the platform from IVECO. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

Cable length and connector keying are part of the specification. A cell with correct electrical output but the wrong lead length will not route to the OE bracket.

Fitment for IVECO and OE cross reference

BG 201139 replaces 2 OE references: 2296801 and 5WK9 6695C, covering cross applications. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 201139 includes IVECO, typically on Stralis / EuroCargo Euro 6. Coverage lists are a starting point for identification, not a substitute for checking the OE number on the vehicle.

Where several OE numbers appear against one BG reference, they are supersessions or regional variants of the same specification. Ordering by 2296801 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 2296801

These complaints bring a vehicle in with the IVECO nox sensors under suspicion. None of them prove BG 201139 has failed on its own, which is why the checks below matter before a replacement is ordered.

DEF over-consumption with no visible leak
torque derate or speed inducement with a full, in-spec DEF tank
no communication with the sensor control module after a cold start
sensor value frozen at a fixed number once the exhaust warms up
dosing shut-down after a few minutes of steady-state running

Checks before fitting BG 201139

Aftertreatment faults are usually system faults. Working through these checks prevents a repeat failure after the new nox sensors is fitted.

Check for a pending software or parameter update for the sensor control module on that platform.
After fitting, run the manufacturer's adaptation or relearn so stored efficiency counters reset.
Compare upstream and downstream NOx readings warmed and under load — idle values prove nothing.
Confirm supply voltage, ground quality and bus termination before condemning the sensor module.
Inspect the harness for heat damage and the connector for moisture and green corrosion.

Quality, packaging and ordering 201139

BG 201139 is manufactured and tested to aftermarket replacement standards, with electrical, leakage and functional testing carried out before packing on the 24V specification. Bulk and retail packaging, private-label cartons and customer-specific labelling are available for distributors and workshop groups.

Send OE 2296801 or the number printed on your part, the engine code and the vehicle identification number with your enquiry, and our technical team will confirm the correct reference, current stock position and lead time before you commit to an order.
