Hi all,

Urgently require data on OE lambda # 22690-AA500, this is a 4 wire zirconia sensor, approx 650mm wire length, with a 4 pin connector block fitting.

Can anyone with access to a Subaru CDRom confirm which models this fits (I think it should be 1994-2000 UK spec cars with EJ20 engine) and where abouts on the exhaust system it fits (I suspect it may be a center section sensor?)

I would be very grateful if some one can confirm the above as we are getting conflicting info back on the part.

Finally am I correct in thinking the lambda nearest the engine (behind the turbo?) is a 3 wire with a short wire length an OE # 22690-AA321 with black/red/white wires?

Thanks in advance

Rich

 

hi the 4 pin connector is the one in mine which is connected to the cat. in my 95 wrx hope this helps. what year is yours ?

 

Sounds more like a newage lambda off the exhaust headers? They are 4 pin with black sheath to wires.
Newage centre section Lambda is slightly shorter and has yellow sheath, but is also 4 pin.
All classic lamdbas I've come across are 3 pin?

Nick, I trawled through dozens of sites last night and the info varies massively, the 3 pin 22690-AA321 sensor is the most common on classics, yet other companies do list the one I mention as being for the models I list??

I need some sort of hard evidence to go back to our manufacturers!!

 

1994-2000 UK spec cars (i.e. Classics) only have one Lambda sensor and its in the downpipe straight after the turbo. There definitly isn't one in the centre section!

 

Thanks Graz, that is a good start

 

OE lambda # 22690-AA520 will fit an 02 newage center section if it helps you,
maybe in process of elimination
