Frequently asked questions

What does the LR104388A NOx sensor do?
The LR104388A is a NOx trap temperature sensor fitted in the exhaust aftertreatment system on EU6 diesel engines, monitoring exhaust gas temperature at the NOx trap and DPF to keep emissions control working correctly.
Which Land Rover models use the LR104388A NOx sensor?
Fits the Discovery 5 (L462) from 2017, Range Rover L405 from 2013 and Range Rover Sport L494 from 2014, all with the 3.0-litre V6 Gen2 diesel engine, EU6 emissions standard with DPF.
Why does the NOx sensor fail on these diesel models?
NOx sensors typically fail from prolonged exposure to hot exhaust gases and soot contamination on the sensor tip, or from corrosion in the wiring connector. Common symptoms are an engine management light, a NOx trap or emissions fault code, and sometimes reduced engine power (limp mode).
Can the NOx sensor be replaced without a garage visit?
Replacing this sensor is typically a straightforward DIY job for someone comfortable working under the vehicle, usually just unscrewing the sensor and unplugging the connector. No welding or exhaust system opening is needed, though the vehicle should be cool to avoid burns from the exhaust.
