Title: Help Needed
Post by: star_whites on 21 May 2007, 18:11:35
Well Ive just had my 1998 2.0 auto returned by the mechanic after having the head done and its still oppsed. He has done the head, replaced the t/belt and pulleys, plugs/leads, oil/filter and fitted two new tyres but has brought it back with the engine management light on.

He says that she has no power when trying to drive it and is idling eratically. I havent started her up myself yet however he did mention there were three faults and I havent a clue what.

His recomendations are I get an electrician to fix it!!!!!!!!!!!!

Any one got any ideas...

By the way I havent paid him yet  >:(

... start with the paperclip test (accessible here (http://www.topbuzz.co.uk/info/fault_codes/fault_codes.htm)) - post the results ... sounds like it could be a duff DIS pack and/or HT lead(s) though ...

Just printed instructions for paperclip test and going to try.

He has changed the ht leads so ??

i should think NOT, what kind of mechanic is that.....car idles erratically and he is arseing about with tyres and avoiding the real issue.

Idle control valve needs a right good clean ( carb cleaner) check all breathers and Ignition leads and paperclip test to see what the fault codes are.

When you have the codes report back here  :y theres a how to on paperclip test somewhere on here  ;)

Could it be the crankshaft sensor? possibly , maybe, hopefully?
Title: Re: Help Needed
Post by: Marks DTM Calib on 21 May 2007, 19:08:49
More likely to be 're-fitter' error  ::)

Don't pay him until he has sorted the car out for you and until it is running perfect!!!!

Well I have got the car keys back and started her up myself. She starts fine as if nothing is wrong, however sport mode wont engage, winter mode wont disengage and when you give her a few revs she stutters like hell then settles back down.

THe fault codes that are showing are:

Cam Shaft Sensor
Throttle Sensor
Kick Down Sensor
Idle Sensor

She is also showing autobox on the computer screen??

Any ideas appreciated.
Title: Re: Help Needed
Post by: Markie on 21 May 2007, 23:07:46
they certainly all seem related, but often one error messgae in a sensor will pass on its problems to another - so only one issue here, solve it and your car is fine.

Possibly cam sensor as listed but im not convinced....yet...as i thought that would be more like an intermittant start than a bad running car  :(
Title: Re: Help Needed
Post by: ians on 22 May 2007, 00:04:56
For starters I would give the throttle body/idle valve and the breather hoses in the vicinity a good clean, incl the small hose and port under the throttle body - all of this can affect idle and throttle response on the 2L,and check all hoses/connections are refitted properly.   Easy diy job.

I concur with the comment about fitting tyres etc when the car isn't running properly, what cr@p.

Hi there
When my Cam and Crank sensors went, it would miss when revved and if it’s in limp mode I don’t think you can engage the sports or winter mode, I also had the autobox warning light lit on the tid display. If cleaning the ICV and breathers don’t work try changing the cam sensor, as it is a stored code and see if that improves things.  

Good luck :y

This might be off the mark, but is the TPS ok?
Title: Re: Help Needed
Post by: star_whites on 22 May 2007, 18:08:54
Update........No new news. Just finnished work so Im going to go check out the hoses however I need to order the throttle body gaskets from the dealer prior to stripping it down as my local car spares informs me its a dealer only part!

Brother in law is forwarding the number for an auto electrician he knows this evening so hopefully I can get him out pretty soon.

Where abouts are the crank sensor and cam sensor, anyone got pics as it does not show you in the haynes manual (Typical) and any idea if its a dealer only part or if its available else where??
Title: Re: Help Needed
Post by: star_whites on 22 May 2007, 18:56:04
Ok just been out with paperclip and placed in right slots this time lol

Would not work with engine on, however worked with engine not running.

Now I think I got this right, when I first tunred ignition on it did:

10 flashes
pause
1 flash
pause
2 flash
pause 10, pause, 1, pause, 2, pause 10, 1, 2, 10 pause
10
pause, 3, pause, 4, pause, 10, pause 3, pause, 4, pause 10 and kept repeating

Any ideas or have I done this wrong??????

Pulling my hair out!!!!!!!!!!!

hi all.
sorry to but in to this thread,but this sounds very simular to the problems i'm having with my beast, she's a 95 2.0 16v, runs sweet untill she's hot and if it dosen't cut out and go into limp home when i re start, she goes straight into limp home when i  start up . leave it a couple of hours and it's fine again untill re start.the paper clips telling me, 92 (cam sensor) and 94(hall effect sensor ? ). is it worth me changing the cam sensor or do i just need to go mental with the idle control valve,
would be greatful of any advice.
all the best

Seeing as it is complaining of cam sensor, I would replace it.

Ok, so diagnosis is Cam Sensor. So question will be where is it situated on the engine??

On the 4 pot, pop the front cambelt cover off, it's held on by one E8 torx bolt.

Plugs in from the top near the cambelt cover.

Post by: curly on 22 May 2007, 23:16:43
hi mate,the cam sensor is situated behind the black cover at front of engine were the cam belt is,you have to remove the big auxillary belt first to get to retaining torx bolts in cover,the sensor is then in front of you on the inlet/left side of cam with two 8mm torx bolts and a lead connected to plug around the manifold area then just pulls off block,it sounds like his damaged/cracked it in doing repair as this puts the engine into limp home and stops it revving above 2500rpm stationary or driving,hope helps you out ,good luck,curly.

Post by: star_whites on 22 May 2007, 23:19:07
Thanks

Will try and get hold of a cam sensor tom morning whilst at work  ::) then will try and fit it tom evening.

Without sounding too thick does the fan belt have to be removed to remove the cam cover on her. Ive never taken a vauxhall apart before only fords, and to be honest up to now have avoided it. lol
Title: Re: Help Needed
Post by: star_whites on 22 May 2007, 23:39:00
Thanks Curly

Will let you know how I get on once I get hold of a new Cam Sensor  :)

Aux belt off is a ten second job - literally

There's hardly anything in the way

Ok, heres an update as promised!

Stripped belt and timing cover, removed old cam sensor to be replaced by new one. On inspection of new one, found that wiring cap is different so had to change wiring loom (This came with new one from Vauxhall). On changing wiring found old cables dont match the new ones (colour wise). Have tried all combinations to no avail ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

So still in same situation. Do u think there are two different types or is it usual to have to change the wiring??
Title: Re: Help Needed
Post by: star_whites on 23 May 2007, 22:35:52
One more update. After replacing the cam sensor and giving up I did another paperclip test. The results were:

0120 = Throttle Potentiometer Sensor (TPS)

0340 = Camshaft Sensor (Not sure if I got right one!!)
Title: Re: Help Needed
Post by: TheBoy on 23 May 2007, 22:40:38
cam sensor errors can throw some false codes...
Title: Re: Help Needed
Post by: star_whites on 23 May 2007, 22:42:56
Thats fine but how do I tell If ive got the right cam sensor and how can I find out which wire to connect to what wire.  :o

What is part number, someone here should be able to look up.  IIRC, they did come with a bit of replacement loom, as the plug as changed so you have to join the wires.

Ok the old cam sensor has this listed on it:

Siemans
5WK9 055 1
90 458 252 GM

5299b

The new one is on the car but the details on the box are as follows:

1 # 93171450
90 12 039
GR.2.510

Any helps appreciated as this is driving me nuts.

Still cant believe it came back with all these b####y faults!!

Hi there try this link, I find it handy finding pics of parts   http://fpuk.co.uk/products/findapart.htm
When I did my cam sensor I had to solder onto the loom, it’s just a mod on the part.
Hope this helps.

90 458 252 is the correct Vx P/N for the Cam Sensor for X20XEV engine according to EPC.

93171450 is the correct Vx P/N for the Cam Sensor for 2.0L 16v engine according to Trade Club book.

So it seems that you do have the correct part...?
