Lambda connection/ fault code 33?
Hi All,
Newbie again! I have a couple of issues with my93 WRX. First is the lambda connection itself. I can see the lambda in the downpipe and the 3 wires coming off it which end up in a plug, however the plug is not connected to anything! Might explain my high fuel consumption??? Anyway, I don't suppose anyone out there knows where the other end of this connection would be?
Also my CEL has made an appearance and I have diagnosed fault code 33 (speed sensor). Can anyone tell me where this is/ what could be the real problem? Speedo head is also broken so not sure if this is related? Help and wisdom much appreciated. Thanks.

overheat sensor
I thought the lamba sensor was in the headers ...not the downpipe
Far as i know that one you are on about is the cat overheat sensor..which does not matter if connect or not.
I maybe wrong but thats whats on my 96 wrx.

Not sure if this is relevant but I have been told that I have a decat pipe fitted? Help and wisdom much appreciated. Thanks.

the lamba plug on the classic scoob is about 4" after the turbo in the down pipe!
the plug has 3 wire's and there is another plug lurking around that area that i connects to , have a look under the intercooler near the gear box bell housing

Scoobymods, on older WRX's the lambda is in the exhaust headers, not in the downpipe.
Look under the drivers side bumper and you will see it sticking out the headers.
If you can take a pic of what you're looking it it might help. Has the downpipe been changed for a decat one? What does the plug connector in the DP look like? The lambda one is quite chunky and has 3 spade connectors inside it.
The cat on fire sensor is much smaller and the connector is also quite small.
With regard to the speed sensor, not sure but do a search.
