Was hoping to have my STi 1(MY94) this week.But the garage just called to say that me car failed it's SVA due to high exaust emissinons.They say this is due to a faulty lambada sensor?
Can someone please help explain how this to me as I"m a scooby newbie.
Thanks for any replies:-)

 

The lambda sensor is in the exhaust and measures the air/fuel ratio so the ECU know how much fuel to squirt in.

Thanks
