FAQ

Q1: What is this NOx sensor used for?

A1: It measures nitrogen oxide (NOx) in diesel exhaust and sends data to the SCR system to control AdBlue (DEF) injection and reduce harmful emissions.

Q2: Are LR104387 and T2H19036 the same part?

A2: Yes.

• LR104387 = Jaguar Land Rover OEM part number
• T2H19036 = JLR internal reference
  They refer to the same rear NOx sensor used in 3.0D SCR systems.
  

Q3: Where is this sensor installed?

A3: This is typically the rear NOx sensor, installed after the SCR catalyst in the exhaust aftertreatment system to monitor emissions efficiency.

Q4: Which engines use this sensor?

A4: Mainly 3.0L V6 diesel engines (TDV6 / Ingenium variants) used in Discovery, Range Rover, Range Rover Sport, and Velar models.

Q5: What are common failure symptoms?

A5:

• Engine warning light
• AdBlue / SCR system fault
• NOx efficiency error
• Limp mode (reduced engine power)
