Ammonia (NH3) Sensors
SCR ammonia-sensing modules for Euro 6 diesel aftertreatment. All 15 OE cross-references and all 15 housing styles are listed below. Send the OE number and a photo of the original part so we can confirm the match before quoting.
Ammonia-slip sensing, matched by the number on the old part.
An NH3 sensor module is specified by the platform, the connector and the housing — not by appearance alone. The same die-cast body is used across several OE numbers with different calibrations and label layouts.
One housing family, many part numbers.
Rectangular die-cast aluminium body with two side mounting ears, twin connector prongs on the top edge and a moulded rear cover. Some versions ship with a pigtail harness and a cylindrical sensing probe. Because the calibration is tied to the OE number, we confirm the reference before offering a replacement.
- Full OE / OEM part number from the old module
- Vehicle platform, engine and model year
- Front and rear photos showing the housing and label
- Connector pin count and harness length
