lamba sensor

[Rob_bennett]

hi, on my 172 my serv light is on:dapprove: and its on because of my lamba sensor according to a data reader, BUT my car drives fine and it still gives really good mpg, the trip computer states 39.8:approve: on a motorway trip at 70-80ish.

can anyone help as i dont really want to change the sensor for x cost and still have serv on.

cheers for any help
