Hi all,

Firstly sorry for posting yet another Lambda topic, but I have tried to find the info I'm asking for here and I'm still non-the-wiser!

Quick couple of questions: I believe the Lambda sensor on my MY99 Turbo has given up the ghost (error code 32, worsening MPG, terrible idle) so I need to replace it.

Where exactly is it, how accessible is it and do I need any special tools to replace it (I've read stuff about O2 wrenches)? I'm a bit of a mechanical newbie, although I'm handy enough with electronics so I'm not a compelte lost cause, so is it the sort of job someone like myself could do? I'm planning on using a generic Halfords jobby (£30 odd I believe) for the moment as I really need the car working again asap... this should be ok shouldn't it?

Last thing I wanted to say is how amazingly useful these forums are! I wouldn't have known where to start in identifying what was up with my car and the Subaru dealers have been painfully slow and less than helpful. So thanks to everyone who's posted here and made Scoobynet a gold mine of Scooby knowledge!

Cheers,

Richard

 

Look to the right hand side of the turbo heatshield under the bonnet you'll see the downpipe and on the top right near to the bottom of the heatshield you'll see the lamda sensor,its 22mm nut flange with a wiring plug on a short lead,be carefull how you pull the plug apart the clip lifts up not squeezed in,When you fit the new one replace the washer and Dont overtighten it.....
Hope this helps

 

The new one is a generic sensor , you will have to cut off the plug from the original sensor and wire up to the subaru plug from the old one. ( only 3 wires )

the "halfords universal jobby" is not a current line for any Halfords . They are £25 , but only if you can find a store that still has one.

It is called a Lewmark Oxygen Sensor L300.

good luck

You can also get Bosch universal sensors from any Motor Factor (use Yell) for about the same price.

One more thing, you won't be able to solder the OEM connector onto the new sensor wires, as they're not copper (stainless steel I think). Crimps and heated shrink wrap should do you OK.

 

Thanks for the advice guys! I'll buy a Bosch universal sensor and have a go at fitting it at the weekend.

Cheers!
