So i decided to see if the car had any codes stored...here's what i got:

A1 Transmission codes:
1-1-4 open.closed short curcuit for prog. selecter ???
2-2-3 off scale low tps
3-1-3 faulty signal for pnp

So i then proceeded to reset..and when i did i thought i heard a clicking noise in the throttle body area..like the butterfly opened and closed??
checked and codes are now gone..

A2 Engine
3-4-3 fuel pump relay faulty
reset and codes are cleared

A3

2-1-1 no LF wheel signal for moving off
2-1-3 no LR wheel signal for moving off
2-1-4 no right wheel signal for moving off
4-2-4 pressure switch for TRACS faulty or shorted
1-4-2 stop lamp switch faulty

reset codes and they cleared BUT not i have the ABS light on on the dash??? WTF???

can it be a switch or a fuse that has blown???
any advice would be great..thanks

If you have not driven it yet the light might stay on till you drive it.

I would wait an see how fast the codes come back.If they do.

 

Hey Tech, no i did not drive it yet...i will take it for a spin and see what happens...i'll keep you guys posted...it's funny, i didn't have all this abs problems when i had the all season toyo's this summer? only after i put on the winters...very strange..well maybe the codes where in there but it's the first time i see them..
as for the TPS..is there something i should do to clean it? can this problem have cause poor gas milage? thanks

TEMP IN MONTREAL TODAY...-20 C....WITH WINDCHILL...-32C

 

so i took the car out of the garage...and once i started driving the ABS light went off...there is a light snow on the ground the abs and trac control are having a field day....i think these tires i got are either garbage or maybe there is something wrong with them? or maybe i need an alignment? I will see the garage that sold them to me on monday..i had better traction with the caprice (RWD) with the bridgstone duelers on them!

HMMM If the TPS code comes back you might want to replace it.

 

TRANNY:
If the same codes do not return, no worries. These electronic self-diagnostic pick up codes for negligible reasons once a while (even passenger-airplanes do that all the time). Make sure that the fluid is clear red and does not have burnt odor. Also make sure to keep the correct fluid level.

ENGINE:
I would follow Tech. You may also want to replace the fuel pump relay, as it is known to go bad. Unless it was replaced recently, I would put a new one in.

ABS:
What year is your 850? If 96/97, you can ship it out to this guy for repair & upgrade:

If, however, it is 1995 or earlier model, you would have it fix it yourself. This post may be of a ref: https://volvoforums.com/m_58856/tm.htm

Please note, that there are 2 different casings for the ABS module; plastic & metal.

The beauty of electronics is, once something goes wrong no one can figure out the exact cause, including the people who designed it.

Hey JPN how are you?
ya i filled up the tranny fluid..in between the upper and lower markings. Since doing so it hasn't happened (flashing arrow)..the only thing i notice is that when the shifter leaves park the light will flash for a spilt second and go away..this usually happens when it's cold outside..once the engine is warmed up it doesn't do it anymore..I will verify the fluid again, i may do a flush, it's a little dark but doesn't smell burnt.

After i reset all the codes, i was driving around for most of the day and i just got in now (about 11 hours later) and i just checked to see if any of the codes came back and it's all good.

I think that the ABS is kicking in cause the tires i have, i find, are not that great, i'm gonna bring my car to the garage i got them at to check them out...i notice that there is a "howling" long when driving and turning the steering wheel to the right...can the tires be slanted in a bit? i do hop onto the sidewalk a bit at work.
thanks
