Air/Fuel ratio sensor (Lamda)
 

Hi,

Has anyone had the pleasure of changing the Air/Fuel ratio sensor (Lamda) on their 2003 Impreza WRX?

The engine management light has lit, and has been confirmed by a local garage that this is the problem.

The official part number is 22641-AA042. Subaru quoted the price for the part at £274.08 ex VAT.

Others have offered the part for around the £320 mark, and £400 fitted.

Therefore my question is can you get these parts for a cheaper price (ie afermarket Bosch ones etc?)

I am willing to change it myself for a huge saving, although I know they can be a pig to remove because of the heat/expansion etc. Looking forward to a comment or two about this, thanks.

easy job just get the car warm before you try and change sounds very expencive the quotes you have been having how many wires does your lamda sensor have????

shane

First thing I did on mine when I bought it 2 years ago. Couldnt beleive the price quoted by subaru UK!.

Ended up buying one from the states, from a company called RockAuto, 120 quid delivered with all duties etc sorted and its the genuine Denso part! No wires to cut

And arrived in 4 days!!!!

and then copy and paste part number into search, its 141 dollars!

Thanks a lot for all the replies.

Shane, It is the 5 wire one, not the 3 wire.

I have been looking at them in states so that may be the way I go. One went on ebay today for £40 but I missed it :(

Thanks again, will let you know how I get on.
