Hi all, sorry that this is ANOTHER Lambda Link thread:
Does anyone know if the pin out diagrams as supplied by BRD, and in some threads on here are shown from the ECU side of the connector, or the WIRE-OUT side?
I'm embarrassed to bother Bob or Branko again today, but the wire which is supposed to be live on mine, won't light up a circuit tester.
Thanks in advance,
Alcazar

 

what year is your car mate MY98..???

Dan

 

Could it be that you will only get a signal once the sensor is heated up...???

Dan

 

Cheers again Dan.
The problem seems to be that pin 1 is supposed to be switched live, but won't make my circuit tester light up. I've found a switched live elsewhere, so that may be solved.
What IS bugging me is that the diagram I have of the pin-outs from my ECU, as supplied by BRD, can be read in two ways: does it show the connector from the rear, ie:where the wires come out, or from the front, ie: where it push-fits onto the ECU?
I think I want B136 pin 5, but what colour will it be??????
A very confused Alcazar

 

i`m looking at a diagram for a my97(think) ecu wiring chart and from what i can make out the oxygen sensor(i take it that means lambda sensor) is terminal no.21 connector no. b136 for the signal. can anyone comfirm this, and also tell me what colour the wire is if that is poss.

cheers mike

 

Alcazar on my diagram b136 is crankshaft position sensor and camshaft position sensor. thats if were looking at the same diagram.

sorry if i`m making things worse

There was a change between 97 and 98 cars. The diagram I have refers to 98, but gives B136, pin 5 for oxygen sensor. Trouble is WHICH IS pin 5??????
And what COLOUR wire????
Alcazar

 

alcazar,

I think most of the diagrams are viewed so your looking at the connector from the back (where the wires go into the block) as its plugged in.

I think the o2 sensor signal wire is normally white with silver rings around it, it could be different on an MY98 car.


Oh, and make sure you get a real good look at the connector because when i was fiting mine i counted along the wires and got the wrong one because the first position on the connector didnt have a wire in it, it was blank.

Had same problem - MY98 - it is pin 5 on the bottom connector (top row counted from right) - but it's blue !
I initially went for the white & silver one as in all other ecus but that was the speed sensor - weird readings.
Also I had another panic & went thru whole process again until I realised that u don't get a signal until it's warmed up a bit - 30 secs maybe.
But u l live & learn - could probably do whole thing in under 5 mins now.
Easiest place for red & black is behind stereo - ciggy lighter or similar.

 

Is it ok to use a Scotch connector thing, or is it best to solder the wires to the AFR?

Was planning to take the +ve & gnd from the ECU connections, I assume this is also ok?

 

Do 'NOT' use scotch blocks they are crap for connections like this..!!!!

Dan

 

is terminal no.21 connector no. b136 right for a MY 97 uk cr the right one? and will it be white with silver rings?

cheers mike
