Lambda sensor

Lambda sensor
Hi,
The engine light lit up on my dad's '03 WRX the other day. He took it to the local dealer, who diagnosed it as a 'bank 1 sensor', and quoted £250-£350 to replace it. They cleaned it (with an air line or something - I'm working on 2nd hand info here ) which fixed it for a day or two.
I'm assuming it's a lambda sensor they're referring to (best online price I can find is £27+VAT ). I'll put it on my own diags on Sunday, when he's in the area.
My main question though, is whether I could find a suitable replacement lambda locally (eg at a scrappy) that would tide him over until I can get a new one fitted. IIRC there are 2 or 3 different types (in general) - does anyone know what make/model of vehicle I could take one off as a temporary measure?
Cheers,
Iain

The sensor you are refering to is actually the FRONT A/F sensor (wideband), not just an O2 sensor, and the price quoted is about right for Subaru UK supply.

The newage ECU is a bit picky when it comes to the front 02 / lambda as it's a pseudo wideband jobby and does not like non-OEM units. Breakers often have them in, try Scooby Bits or Scooby Spares

Thanks for that... Hunted all around Dunfermline for a suitable sensor-removel socket, before going into a factor's, who gave me one for nothing cos NGK provide them free every so often.

Sounds like exactly the same thing. You don't have the part/item number handy, do you?
I'm guessing it's this one though (in front of CAT)...

Nope... the one above is the rear 02 sensor and checks on the efficiency of the cats, what you need is the "Front" 02 sensor.

You get at it via the wheelarch.

Just looked at the eurocarparts link above again..........hang on, the product description does not match the product title as the Rear 02 sensor does not talk to the ECU about fuelling, that's the front 02 sensor. Might be best to ring but £130 for a front 02 sensor is a cracking price.
