I bought a 206cc in Jan (2.0) Y reg (01) but since having it the MIL has come on a couple of times.
The first time it came up with a code for "Cat In-Efficiency" but I put this down to the blowing back box.
I had the MOT 2 weeks ago and it passed emissions (with a new back box).
This week the code came back with another, P0110 which relates to the IAT (inlet air temp sensor) malfunction.
As this relates to fueling I am thinking that is probably why the CAT has been "complaining".
Does anyone have a spare IAT going spare?

A new one should cost less than a tenner --- try this site
http://www.ignitionleads.co.uk/index.aspx --- they carry EMS sensors for most cars.

They are £9.08 + p & p + vat.
£19.99.
I bought one anyway as I need it asap.
