Bosch Lambda Sensor wiring
Getting CEL code 32 and crap idling so I've ordered the 3 wire Bosch Lambda sensor (£49 +vat). Anyone fitted one of these? - just wondering if it's obvious how to wire it up (believe I have to replace the connecting plug it comes with and wire it to the original plug).
p.s. STi v3 (3 wire lambda in downpipe)
Thanks
Kevin.

Recent thread that may be of use. Yes, you'll need to cut the OEM connector off the old lambda sensor, and crimp it onto the new one (solder won't work very well).

I just located the local Bosch auto agent using their website. My local agent was in Aberdeen, phone call and the part was on it's way.
Judge, thanks, also what are the corresponding colours on the Bosch sensor.

Kevin,
They're on my post above!
Winders,
It does matter, yes. But I happen to know for sure that the 11983 Zirconia is the right part for your MY, because it's the same as mine (MY00).

Just got mine, its a Universal Zirconia Sensor 3 wires as described in the thread. just to be exactly sure. my OEM part has exactly the same colours two white one black, can i presume that the black wire in the oem sensors is also the signal wire?.
Many thanks in advance
