Title: Problem with Power Steering Ultima Cossy
Post by AndreB83 on Sep 6th, 2013, 1:12am
Hey folks,

Got some trouble with the power steering. Its working but not with the full power that is normal  ???

I think there is a problem wit the speed senitive  ??? Valve ???
at the steering rack.

Is it possible for me to repair this? I think it is something like an Valve with a Plug in it.

I allready checked for leaks and dirt in the reservoir´s filter. Fluid is red and clear. Pump is working properly

Has anybody done this before?

Thanks
Andre from Germany

Could be caused by several things..............

1)    A faulty VSS, is your speedo reading ok ??

2)    Faulty pressure switch in the pipe from pump

3)    Faulty wiring from ECU to Switches / Rack

4)    Faulty Rack or Pump

HTH

Sounds like a wiring problem alongside the steering column,probably near the rack. :)

Think so too. Today its rainy outside and it worked until i arrived at work.
This only happens when its wet outside for some miles.

That suggests that water is getting into exposed electrics then

I already replaced some wires in the engineI loom (not engine bay loom) the big one frome rear left wheel to rear front wheel and both of the fuseboxes. Car is running fine now and no electric problems like ABS ant Teaction controll since 10000 km anymore. Today im getting a new speedometer because its showing the wrong pulses.

thanks for your reply

If Speedo is playing up too, it is most likely VSS, and that will affect power steering

Speedo is absolutely correct. Also via obd

Changed the combi intrument this evening. Looking brand new with new lamps.
??? Same Failure  ??? On idle it shows round 3000 rpm an it is dancing up and down.


But i can tell u that its possible to swap over all combi instruments from 2.0 2.3 and 2.9.

they are all the same.

Any Ideas?

The pulses for the rev counter are taken from the alternator. Make sure that the plugs and leads to the alternator are all tight.

All the wiring diagrams for the scorpio are on line on my web space if you need them (https://skydrive.live.com/?cid=EB36F845EA9B8FB6&id=EB36F845EA9B8FB6!146)

Presumably you got pulses data from here:
http://www.fordscorpio.co.uk/instreset.htm

In the same box it says “engine speed signal coming from the alternator, (12V V6, 2.5 TDi) or the EDIS (all others)” so yours being a 24v should be coming from the EDIS.

Thanks
Couldn´t believe that the signal comes from alternator. Renewed the whole wiring loom. could remember that.

Checked the alternator and there is only the blue cable for the charging control lamp in the combi instrument.

the faster i drive the higher is rpm. for example if i drive like 120 km/h its locked at 7000 rpm (it´s stuttering :) )

Found loose ground cable from my repair session near the left headlight. connected it but with no success.

@ snoopy: Many thanks! Your wiring diagrams helped me half a year ago fixing the wiring loom

I’ve seen this problem reported before but don’t think I’ve seen a solution. If it were me I’d try running a fresh wire from the EDIS to the revcounter & keep it away from the rest of the loom especially if it runs near the cables from the PCM to the EDIS, although those 3 are shielded (shown in the diagram) there may be a problem with the shielding.

Rev Counter signal actually comes from ECU pin 48 which is also wired to EDIS Module (PIP & SPOUT Signal)

Dave,the Scorpio Snoopy had was a 12valve,hence his reference to the alternator powering the tacho,they did not of course have EDIS.

Found!  ;D

Found two not correctly connected ground wires. One at the left headlight and one near the passengers seat from ECU.


The Power steerings works perfectly and the rev counter also.
Thanks for ur help guys
