Lambdasonde (zuurstofsensor) gemonteerd op de uitlaatpijp, vóór de katalysator, in het motormanagementsysteem van de 4.0/4.6L V8 benzinemotor.

De voorste sensor meet het zuurstofgehalte van het uitlaatgas wanneer het de cilinderkop verlaat en stuurt dit signaal terug naar de motorregeleenheid. De module gebruikt dit om het lucht-brandstofmengsel in gesloten-lusregeling te houden, waardoor de brandstoftoevoer nauwkeurig blijft en de verbranding efficiënt is.

Vehicle Model Land Rover Discovery 2 1998-2004 (L318)

Fitment Notes DISCOVERY 2 1998-2004 — 4.0/4.6L V8 Benzine. Voorste zuurstof-/lambdasonde, op de downpipe.

Frequently asked questions

What does the front lambda sensor do on a Discovery 2 V8?

The front lambda sensor measures the oxygen content of the exhaust gas leaving the cylinder head and feeds that signal to the engine control module. On the 4.0/4.6L V8 petrol Discovery 2 it sits on the exhaust downpipe, upstream of the catalytic converter, letting the ECM hold the air/fuel mixture in closed-loop control.

Which sensor position is this, upstream or downstream?

This is the front (upstream) sensor, mounted on the downpipe before the catalytic converter. It's the pre-cat sensor the ECM uses for live fuelling corrections, not the post-cat sensor that monitors converter efficiency. Fits the Discovery 2 4.0/4.6L V8 petrol.

What are the signs a front oxygen sensor is failing?

Common signs on the V8 Discovery 2 are poor fuel economy, rough or uneven idle, hesitation and an illuminated engine warning light with an oxygen sensor fault code. A lazy or dead sensor typically pushes the ECM out of accurate closed-loop fuelling.

How do I confirm this fits my vehicle?

This front lambda sensor fits the Land Rover Discovery 2 (1998-2004) with the 4.0 or 4.6L V8 petrol engine. It does not apply to the Td5 diesel. Check your engine type before ordering, as petrol and diesel exhaust sensors differ.
