There are 2 of these sensors fitted in the manifold with the pre cat. Lambda or Oxygen sensor measures the amount of oxygen in the exhaust system. It sends signals to the on board computer which adjusts the air/fuel ratio to the correct mixture. How can I tell if it needs replacing? Lambda sensor failure may be indicated by increased fuel consumption, an increase in emissions, CAT failure or possibly the illumination of a 'check engine' light.

Suitable For: mk3
