if you look at the top of the downpipe next to the turbo, you will see the sensor sticking out of the downpipe. the wires from it connect under the intercooler, they are about £90-100 from the dealers

 

cost me about £130 fitted by prosport (i use a lot less fuel now)

thanks alot guys...........

 

i have fitted a de-cat downpipe does will it still be there??
as i dont know much about engines....

thanks again

 

It should be - it'll throw a check engine light...and get very poor mpg.

Look just after the turbo, there should be a small cylindrical object with a few wires going to a white connector there...it's screwed into a welded boss on the downpipe (dead easy to change, even for the mechanically challenged).

Just changed mine on a 95WRX. It was located on the bottom left of the engine.
It cost £44 with postage (Bosch LS02 3 wire).
Do I need to reset the ECU or will it be ok?

Depending on which car it is E.G. early import, the lambda sensor could also be located in the headers, R/H side of car more or less underneath the engine.

 

before i start my car the CEL should be on, but this car doesnt even come on???
is it cos of the lamba sensor???

 

Its probably the light behind the dash, it should come on when you turn the ignition on.

You really want to make sure that one works
