Does BG 201112 replace OE 22827992?

Yes. BG 201112 is listed against 22827992 and 5WK9 7373. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 201112 fit?

Recorded coverage includes Volvo. 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 201112.

Product Description

This BG NOx (nitrogen oxide) sensor is designed for the urea/AdBlue-based SCR (Selective Catalytic Reduction) emissions system on VOLVO FH4 / FM4 Truck Euro 6. It is a direct-fit replacement for OE reference 22827992 / cross reference 5WK9 7373. 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 201112 (OE 22827992): function on the vehicle

NOx Sensor 22827992 is supplied by BEST GROWTH under part number 201112, cross-referenced to OE 22827992, 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 201112 is built to the position defined by its OE application on a 24V electrical system in truck service on the platform from Volvo. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

Fitting position matters as much as the part number: upstream and downstream references often share a housing but carry different calibration data and cable lengths.

Fitment for Volvo and OE cross reference

BG 201112 replaces 2 OE references: 22827992 and 5WK9 7373, covering cross applications. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 201112 includes Volvo, typically on FH4 / FM4 Truck 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 22827992 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 22827992

These complaints bring a vehicle in with the Volvo nox sensors under suspicion. None of them prove BG 201112 has failed on its own, which is why the checks below matter before a replacement is ordered.

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
intermittent fault that clears after the engine cools and returns when hot
SCR efficiency below threshold or NOx-signal-implausible fault codes

Checks before fitting BG 201112

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

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.
Check for exhaust leaks ahead of the sensor boss; a diluted sample reads low NOx.

Quality, packaging and ordering 201112

BG 201112 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 22827992 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.
