95 olds just dies

[rooster]

I really havent got any futher along. I did clean up all the grounds on the eng studs and
raditor support.

I going  the junk yard for some used plugs if needed , that 1 plug for the front sensor is 22
bucks, thats for a 1/2 connection.

I thought I found the problem Saturday, the wire leading the sensor on the back of the
engine. I poked the wire and it killed the engine. I did it again and killed it again. I
replaced the wire and one of the plugs . I couldent kill the engine doing that any more.
But stop on its own and throw a P0341 again.

P0 341 says its CPS range/performance !  It dosent say witch CPS sensor!

When I installed the CPS behind the damper I did not check for any air gap, I just bolted
it in place, if there is adjustment it would not be much. I havent read much about that.

Will the computer have to relearn with these new parts installed?

Went to libary today and got what I could from alldata printed out.

the Exact trouble shooting for the  code you are getting now is back on the first section...   the 2 links directly under where it says 24X ignition control....

here they are again....

these are directly from a gm service manual......  for you exact application...

The code was po341 those charts are for DTC po321, po342, thats were I was confused.

To find terminal GD6 do I just look in hayes manual for that and see what color it is?

Does backprobe mean contact your meter prob into the plug end without unpluging anything?

This is new turff for me, kinds scary looking in there!

my mistake again...

the p0341 is below the cam crank angle error on the first page of this thread... but you spotted that...

yes.. backprobing the connectors...  usually  you can get a pointed probe in..   usually by unplugging the connector and removing the rear cover on the connector.. sort of a plastic shield wire diverter.......

does that computer have 4 connectors to it...   you should be able to extract that box from the glove compartment with it still plugged in...

i see green blue and grey... is there a 4th black one hiding behind the others...


changing the pigtail at the crank angle sensor behind the damper is going to be easier...    use a new one..  price them around..

There's 2 computers !  The one on the bottom has 3 plugs the one on top has 2 plugs.

What wad of wires are you refuring to?

I have replaced all 3 sensors with new ones, I did replace a wire feeding the CPS on the back side of engine by firewall.

[wayne petty]

the P0341 points toward the crank angle sensor behind the damper..

the 489 pigtail at autozone is 20 bucks..


all i could see in that image is one computer... with 3 connectors.. i did not see a black connector body as referenced in the p0341 sections.



do you have piercing type of test clips..... bed of nails...  same type telco guys use...  and the old crank angle sensor... so you can chop into the wire so you don't damage the new wires on the new sensor... for testing ..

the computer will probably have to come out...  unless you are a contortionist...


clips like this are what i use to pierce wires without damaging the wires..

they used to be available at radio shack... but i don't see them online...

Here is another picture, the computer closest to you has 2 plugs, the plug on the right has 8 wires in a white plug:

red
black
pink
green
orange
purple
black
black

I removed the dash speaker and could see a number on it: 910021R04282511, the other number is 16200021.

The shack didnt have the bed of nails neither did granger, I did pick up some hook connecters at the shack.

here is an image of the engine control computer...

looks like only 3 connectors...

the 16200021 is this...

/Anti-Lock Brake Control Module

Application:    Labeled #16200021



did i post this link to the engine control wiring diagram...

perhaps... i should just get one of the ford transit vans... just travel the country fixing cars..

if you were able to access alldata...  there should have been a connector pin out... or numbering chart.. i have not seen one... online... at az...


i am going to try to post this link to the PFI diagnostics...

I didnt see the links with the flow charts , Thanks!!!!!!!!!!!!!!!!!!!
I did a wire color inventory of the blue plug (24 pin)thats in the Olds , the wire colors match the picture of the plug from all data (Libary). Only the plug color is different.

there should be 3 of those charts...  one for each connector...

that is for the 24 pin black connector..

Yes, I have all 3 charts.
I got the computer out and down on the floor where there was enough room to work with
it , no screws are bolts just snaps into place,

I started doing to flow chart for DTC PO341

The first box :
po341  set in 34 minutes

The second box:
DVM   says 0.011 volts  I consider this as 0 volts!

The 3rd box:
The test light is on.  
. Not so sure about this because the wire colors dont jive with whats in the diagram
picture. The flow chart tells you to probe terminal C, in the diagram picture terminal C is
the center port, on the car it is the top port with a black/white strip. Looking at the plug
closely the plug is marked A,B,C.

The forth box:
I went to junk yard today and got the computer 29 bucks.

Thats where i'm at now!

[wayne petty]

i would bet that terminal BA12 is on the smaller black connector...

and that GD6 is on the green connector....


see if those wire colors match...

Yes thay do! I only checked the green plug but all the wires on it match, brought the plugs home just to do that, no extra charge, also stocked up on extra connections and another crank sensor, just incase!

[rooster]

I replaced the computer it died in 7 minutes. I'm doing more wire chasing today
Cant find inline harness connector Z in this diagram:
http://repairguide.autozone.com/znetrgs/repair_guide_content/en_us/images/0996b43f/80/21/66/f9/large/0996b43f802166f9.gif

Going back to libary and check alldata for harness diagram if there is one. Made some inline jumper to go over the car orignal harness plugs, I sure wish I had that bed of nail clamp like yours. I have a min max meter to try out on each circut to find witch is failing. Now I'm having fun!!!!!!!!!!!!!!1

[rooster]

Here's where i'm at!  Still getting po341 with the jumper wires in place, still have the +
to do. I have replaced the plug on the harness side of the cam sensor.

Going junk yard shopping tommoro for another computer and used plug for the harness
side of the crankshaft sensor (24x). probly pick up a ignition control moduel to.

Also replaced the new cam sensor with another new sensor.

I have a question:
I replaced the 24x crankshaft sensor behind the damper, I have read but have got any
answers yet that the damper has a reflective material inside its vained reluctor, in the post
I read it warned not to extend the bolts of the puller to far or it would perice the material.
Only 1 of the 3 bolts holes could do this.

I cant say that this is true or not, I didnt look when I pulled and re-installed the damper.
Code po341 says that the computer is reciveing to many pulse's.from camshaft sensor!
When that happens computer go's into limp home mode! I can't see in there without
pulling the damper.

Can anyone confirm that a reflective material exist?
Can computer be tested?
