I know the code is all about intake air temperature, but I have no idea where the intake air temperature sensor is.  Is this part of the MAF? and if so is it just a straight MAF change that is needed?

Car runs absolutely fine, 33MPG (on LPG) and goes like a stabbed rat, so it can't be over serious, or can it?

What do I need to do to fix it?

If it is just the MAF I wouldn't be surprised, the engine has had a lot of work done on it lately due to the cam  box gaskets failing, both coil packs (oil boiled - cracked plastics, and water ingress on the other)and the air-con condenser, and the lambda sensors, and coils springs on the front, so most of the top and front has been in bits lately and the MAF is original - eight years old, and presumably fragile-ish after this time.

All help welcomed.

Thanks in advance.

yes it is on the 2,6 so guessing you are going to need a new one

And have heard from JB, the 2.6-3.2 Mafs are known to be unreliable! replace that THEN see how it shifts!!

Only buy a GENUINE replacement or it will be wasted money 

[Jimbob]

As above, 2.6 / 3.2 MAFS are a common failure.

ebay specials best avoided.

BOSCH are the ones to go for, from wherever has em the cheapest
cross reference the 3.2 omega maf search, with the bosch part number, they can be cheaper when they are being used in a van etc as used in a fair few vehicles.  expect to pay just under £100

Original part is a Bosch product  I paid some 120 EUR a few years back from a motor factor/local speed-shop. Easy to change, impossible to clean or inspect and so far has been the best cure for 0170 or similar related codes

Thanks all, I have found the following so far -

http://www.vauxhallworldparts.com/partsearch/partdetail.php?partid=241&partlinkid=3314&vid=21&ecode=26&cont=true
It works out at about £110 delivered to my house, so not too bad, and a whole load of non-genuine which I shall not be buying.  I also have a trade club card so I will ask my local stealer, just for a laugh, to see what number they pick.

Thanks again.
