FAQ

Q1: Are FPLA-5J299-EC and LR104388 the same sensor?
A1: Yes. FPLA-5J299-EC is the Jaguar Land Rover reference, while LR104388 and LR063032 are OE numbers used for the same NOx sensor assembly in SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Land Rover Range Rover, Range Rover Sport, Discovery, and Jaguar diesel models equipped with SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet NOx sensor depending on exhaust configuration. Many Land Rover/Jaguar systems use the same sensor type in multiple positions with different harness lengths.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in the exhaust and sends data to the ECU, which controls AdBlue dosing to reduce emissions and maintain SCR efficiency.
