FAQ

Q1: What is this NOx sensor used for?

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

Q2: Are LR071822 and LR118316 interchangeable?

A2: Yes.

• LR071822 = earlier OEM JLR reference
• LR118316 = updated OEM JLR reference
  Both belong to the same NOx sensor family used on Ingenium 2.0D engines.

Q3: What is GH22-5J299-AC?

A3: It is the supplier reference number for the same NOx sensor assembly used in JLR SCR systems.

Q4: Where is this sensor installed?

A4: It is installed in the exhaust aftertreatment system, typically as SCR inlet or outlet NOx sensor depending on configuration.

Q5: Which engines use this sensor?

A5: Mainly Jaguar Land Rover 2.0 Ingenium diesel engines used in Discovery Sport and Range Rover Evoque L538 platforms.

Q6: What are common failure symptoms?

A6:

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