emissions fault

Postby Robobone » Wed Jul 18, 2018 1:03 pm

hi everyone
i have a 2007 Meganne convertable 2.0 l which is throwing up check emmisions.
had a test done and fault was lamba sensor codes were reset came back on after a week code showed catalitic convertor. warning lights went off now back on.
as I work in the exhaust industry i get at cost price decided to get cat and sensor changed.
now my question
mechanics rekon there are two lamba sensors on a cat but the cat showing at work has only one so i am not sure what is correct.
any idea?

Hi,
according to the almost useful Haynes manual, there are 2 sensors.
One in the exhaust manifold and one downstream of the cat.
Good luck
Bob.
