O2 sensor wiring
O2 sensor wiring
(OP)
Hello,
This is my first post but I am sure I'll visiting quite a bit.
I need help with an AC DELCO AFS-65 Wiring assignments. I had never encountered such people where they flat out refuse to give the information as if it is a big big secret.
Anyway, it seems like This sensor is equivalent (replacement) to GM 25161151 used on 94-95 Corvettes and 25133504 and 25165313 which are used from 93 to 96 Centrury Skylark, LeSabre, Park Ave, Rivera, Regal and Road master.
I am hoping somebody can help me identiying which wire is for what (may be from a wiring diagram for the above cars or something).
If not, is there a way to identify these wires through testing?
This Oxygen sensor has the following wire colors (in connector sequence):
Bage - Thick wire and is Attached to the body
Purble - Thick Wire goes inside the sensor
Black - Thinner wire goes inside the sensor
Orange - Thinner wire goes inside the sensor
Thank You
Mike

RE: O2 sensor wiring
Basically, you have a 4 wire heated sensor though, best guess at present would be purple/sensor Orange/heater power Blacks/ground.
Do a Google search on 4 wire heated O2 sensors or AFS65 Oxygen sensor. If anyone has ever put it on the Internet, you should be able to find it.
RE: O2 sensor wiring
To understand what you are going to measure read, for instance, these articles: http://www.asashop.org/autoinc/july97/techtotech.htm
and http://www.asashop.org/autoinc/april2000/techtips.htm
If you have a scope you can probably learn a lot from Jaff Bach's articles in Autoinc., one such an article would be http://www.asashop.org/autoinc/jan2001/techtotech.cfm
Backprobe the purple wire with a DMM or scope.
Good luck
RE: O2 sensor wiring
I think I may have enough to proceed with the installations but I'll do some testing after I read the articles.
Thanks Again
