Hi John.

Don't go rushing to get a lambda sensor just yet.

I would be looking for an air leak first. Any noise around the exhaust manifolds, especially when cold?

Hi John

Laidback is very wise.  I have a similar problem with mine & lambda (oxygen) sensor was highlighted as fault at Vx - who wanted to change it, but didn't.

Took it to an Independant who explained this sensor was picking up a weak air/fuel mixture hence the fault light - which will be the orange one that looks like an engine on your dash I presume.

My light has been on for 2 months now and lambda fault now cleared by itself - but latest code points to MAF sensor, which Vx also wanted to changed but still most likely an air leak at the manifold.

Often worse when cold as leak seals itself when engine warms up.  Your fuel consumption will probably suffer too.

o2 senor two voltage low...i.e its lean.......as in it could be a leaking manifold or simialr.
