FAQ

Q1: Is LR112139 a NOx sensor?
A1: It is commonly listed as a NOx-related exhaust aftertreatment sensor, and in Land Rover systems it is used for NOx trap / exhaust monitoring functions depending on engine variant and emissions layout.

Q2: Which vehicles use this sensor?
A2: It is used on multiple Land Rover and Jaguar Land Rover platforms including Discovery 5, Range Rover, Range Rover Sport, Velar, and New Defender diesel models with SCR/aftertreatment systems.

Q3: Is this inlet or outlet sensor?
A3: It can be installed in different positions depending on the exhaust system design (front or rear NOx/aftertreatment monitoring positions). Always confirm by VIN for exact placement.

Q4: What does this sensor do?
A4: It monitors exhaust gas conditions (including NOx-related aftertreatment behavior) and helps the ECU control AdBlue dosing and emissions efficiency in SCR-equipped diesel systems.
