Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
NOx Trap Temperature Sensor - an exhaust gas temperature sensor within the diesel exhaust aftertreatment system, located at the NOx trap (lean NOx trap / NOx storage catalyst).

It reports gas temperature to the engine management system, enabling the ECU to control aftertreatment operation and regeneration cycles. Fitted to 3.0L V6 diesel applications running EU6 emissions control with a diesel particulate filter.

Frequently asked questions

What does the LR104388LR NOx Trap Temperature Sensor do?
The LR104388LR NOx Trap Temperature Sensor is an exhaust gas temperature sensor at the NOx trap in the diesel aftertreatment system. It reports gas temperature to the engine management ECU, which uses it to control aftertreatment operation and regeneration cycles on 3.0 V6 diesel EU6 engines with a DPF.
Where is the NOx trap temperature sensor located?
The NOx trap temperature sensor sits at the NOx trap, the lean NOx trap or NOx storage catalyst, within the exhaust aftertreatment system downstream of the engine. It typically threads into the exhaust near that catalyst stage so it can read gas temperature. Fitted to 3.0 V6 diesel Land Rovers.
What are the signs the NOx trap temperature sensor needs replacing?
Signs typically include an engine warning light, stored temperature-sensor fault codes and disrupted DPF regeneration. On these 3.0 V6 diesel Land Rovers a failing NOx trap temperature sensor can push the engine into reduced-power limp mode. Left unaddressed, poor regeneration control can eventually lead to a blocked DPF.
Which Land Rover models take the LR104388LR sensor?
The LR104388LR fits the 3.0 V6 diesel EU6 engine with DPF in the Discovery 5 (2017 on), Range Rover L405 (2013-2022) and Range Rover Sport L494 (2014-2022). Discovery 5 covers Solihull build from VIN HA000001 and Nitra build from VIN K2000001. Confirm your engine and VIN before ordering.
