NOx Sensor 5462436

BG 201097 (OE 5462436): function on the vehicle

NOx Sensor 5462436 is supplied by BEST GROWTH under part number 201097, cross-referenced to OE 5462436, as a direct-fit aftermarket nox sensors. In service it runs a heated zirconia measuring cell inside its own sensor control module, converts the raw cell current into a NOx value in ppm, and publishes it on the bus. The engine controller cannot calculate dosing quantity or conversion efficiency without a plausible signal from it.

BG 201097 is built to the position defined by its OE application on a 24V electrical system on platforms from Cummins, DAF and IVECO. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

Because the sensor carries its own control module, most "sensor" faults are really bus, supply or ground faults at the connector — the electrical side is worth ten minutes before the part is ordered.

Fitment for Cummins, DAF and IVECO and OE cross reference

BG 201097 replaces 3 OE references: 5462436, 2894940 1705572 2294291 2659850 and 5WK9 6675A 5WK9 7401, covering cross applications. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 201097 includes Cummins, DAF and IVECO, typically on ISX15 / X15 Engines (24V). 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 5462436 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 5462436

These complaints bring a vehicle in with the Cummins and DAF nox sensors under suspicion. None of them prove BG 201097 has failed on its own, which is why the checks below matter before a replacement is ordered.

• 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
• upstream and downstream values reading almost identically under load

Checks before fitting BG 201097

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

• Check for exhaust leaks ahead of the sensor boss; a diluted sample reads low NOx.
• Read the sensor's own dew-point release time — a cell that never heats is a supply or module fault.
• Verify DEF concentration with a refractometer before blaming the measuring cell.
• 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.

Quality, packaging and ordering 201097

BG 201097 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 5462436 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.

Frequently asked questions

Does BG 201097 replace OE 5462436?

Yes. BG 201097 is listed against 5462436, 2894940 1705572 2294291 2659850 and 5WK9 6675A 5WK9 7401. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 201097 fit?

Recorded coverage includes Cummins, DAF and 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 201097.
