FAQ

Q1: What is this LR104387 sensor used for?

A1: It is a NOx trap temperature sensor that monitors the temperature inside the NOx trap (part of the emissions system) and sends data to the ECU to control regeneration and emissions performance.

Q2: Is this a NOx sensor or temperature sensor?

A2: It is a temperature sensor for the NOx trap system, not the NOx measurement sensor itself. It helps the SCR/DPF system manage emissions efficiency.

Q3: Which vehicles use LR104387?

A3: It is mainly used in Jaguar Land Rover diesel platforms including:

• Discovery 5 3.0D
• Range Rover 3.0D
• Range Rover Sport 3.0D
• Range Rover Velar diesel models

Q4: Where is this sensor installed?

A4: It is installed in the exhaust aftertreatment system, near or inside the NOx trap/catalyst assembly to monitor temperature conditions.

Q5: What are common failure symptoms?

A5:

• Engine warning light
• Emissions system faults
• Incorrect regeneration cycles
• Reduced engine performance (in some cases)
