Hello guys, I've a 94 7AFE manual transmission and I need the ECU wiring diagram of my car or just to know if 7AFE and 4AFE pins are the same.
If none available I just need to know which is the ECU pin for the O2 sensor SIGNAL.
Thanks

Edoardo

Eduardo,
Sometimes it's worth checkin the older pages of the forum, you usually find that your question has been raised before, here's the link I posted last time

http://www.geocities.com/MotorCity/Pit/997...ct/Pinouts.html

You can check the oxygen/Lambda sensor voltage at the DLC1 (data link box)
in the engine bay (Voltage between pin TE1 and E1/Earth),

I have already seen all posts, your too, but in the link that u posted there isn't the 7AFE ecu and I don't think that it could be similar to 5SFE due to the different engine family (A vs S)
Maybe it could be similar to 4AFE ECU but who can confirm this?!?!?!

Thanks

Edoardo

Ok, you've forced me into pulling my finger out >>
The 7AFE (1.8ST) has 2 oxy sensors, main one is hooked
up to the Data link connector on the left rear of engine bay,the same link runs of to the ECU pin 6, pin 5 being
the second sub oxy sensor, both wires are coloured white,

But....you've a full diagram of my ECU!?!?!!?! please send it to me, also through PM....I need it also to wire my SAFC2

the image I have of the ECU is held in a format specific to
an exclusive program and so isn't capable of being
converted to another pic format. I'll have to print it up
and image capture it and email it to you sometime Monday,

Jon

Thanks!!!!!!!!!!!! you save me!!!!!!!!!!!!!!!!!!!!!!!!! >> >> >> >> >> >> >> >> >> >>

PS:my model is 7afe manual transmission with AC.

Ed,

your in luck, I've got a third party software image capture program which will convert
the diagram "on screen" to a BMP format. Will post the files to your email as attatchments. Files are about 2Mb each, top and bottom clips of the ECU pinouts.
You'll have to zoom the pictures to get a clearer view of the small print. Post back
on this forum if you get the files OK,

Jon

Ok,you're my saver!! thx >> >> >>
