FAQ

Q1: Is LR140308 a NOx sensor?
A1: Yes. LR140308 is a Land Rover NOx sensor used in diesel SCR (AdBlue) emission systems to monitor nitrogen oxide levels in the exhaust.

Q2: What vehicles use this sensor?
A2: It is commonly used on Land Rover Defender, Velar, Discovery Sport, and Jaguar diesel models with Ingenium engines and Euro 6 SCR systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream or downstream NOx sensor depending on exhaust layout and SCR configuration.

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