Title: lots of lights
Post by: amba on 01 May 2007, 21:52:38
Further assistance required please....driving home tonight car again felt lumpy and running uneven..as in speed restriction kept to 50mph but revs going from 2500-3000 and back again..when accelerated after road works eml came on again..slowed down and car eventually died..pulled over to hard shoulder to see if anthing falen off..all intact so tried to start car..thank heavens it did and off i went again albeit like a kangaroo..shortly after dash display flashed up "automatic gearbox" and then gearbox warning light on dash came on and stayed alight..again stopped ..looked and started up..managed to get home although car had vertually no acceleration and at 2500 revs barley doing 30 mph...got home and flashed up fault codes..they are as follows:
73..unsure if this is from earlier fault..have checked all plugs and leads..all sound/tight
22..this states "throttle sensor"..should I buy a new one ???
19..this is a new one today..crank sensor..again should I buy a new one??
assuming these are replaced will car drive as should ..or are these codes just telling me another problem exists..up until yesterday car drove/accelerated and ticked over like a 2.5 v6 elite should ..help please

Need The Boy to comment but I think its likely to be the crank sensor.

If a *new* code 19 has popped up I think that sounds like a crank sensor that needs doing.  I dont know whether the other codes would follow as a result of this or not, need someone like TB to comment on that.

Thats what I was going to do...buy a new crank sensor..fit it and go from there...assume that if sensor was playing up would account for erratic tickover even when engine warm and that may then be issue with revs going to gearbox...trying to think logically

I have read somewhere that if you have a problem with the crank sensor this can put the car into limp mode and the signal is also given to the gearbox ecu so both parts go into limp mode.

Ths could be complete twoddle as I read this a while back but i'm sure someone will be able to confirm.

From symptoms that have occured this does sound like what has happened,so will do the sensor...typical Vauxhall Dealer..rang them this morning to ask if they have one in stock..no guv.!!there are two listed for car ..which one do you need ..9049-2006 at £88=13 and 9049-2061 at £64=04..both need to be ordered and his only advise was to take old one out first to see what the number was...why don,t they have the details when you can give them ..engine no/vin no/etc etc..so looks like need to crawl under car and remove ..any ideas if this is simple to see

Crank sensor is easy to see from under the car.  Get under the car and look up at where the oil filter is on the passenger side of the engine.  You will see a black right angled plug with wires coming out.  This is the crank sensor.  I think that it is held in position with a single bolt which is probably a torx.

If the sensor is failing, you were lucky to be able to start the car again - apparently, they normally die and it is a tow home.  Sort the crank sensor first and then reread the codes and see if the others that you mention appear.

There is an excellent how to guide on the crank sensor replacement by the way.

Hope this helps

Good advice :y

Thanks for advise..and "how to "..is it the plug end that is the difference in the two part numbers or is it the actual sensor??it might be easier to identify from the plug end ??if that is easier to see as dont fancy taking out old one and then refitting it if it is knackered....really strang though car starts fine and is now driving ok as wife just used to go to s/market..better to send her out if it is going to stop as she will get RAC quicker

Post by: Elite Pete on 02 May 2007, 11:55:43
Its the plug end thats different but the sensor is easier to get at
Title: Re: lots of lights
Post by: amba on 02 May 2007, 12:10:03
Is the plug at the back of engine under scuttle panel?? are they just visible or does it need unplugging to see differences
Title: Re: lots of lights
Post by: cdx25 on 02 May 2007, 12:10:06
My sensor part number was readable from under the car - much easier than digging the wiring end out of the loom at the back of the engine...

Although ive never done one they are under the skuttle and I believe difficult to get at :(

If you can see the part number on the sensor, great.

If not, unplug and see whether it is a connector with rounded edges or square edges?

Or, jusat tell me what year it is?

Car was registered 16/06/1998.....W0L0VBP69W1229357..hope that helps..if I know exact part can get next day delivery so up and running properly..although as stated before ..car is running ok so could this all be "red herring"..do these sensors play up and then die or just die
Title: Re: lots of lights
Post by: gofwb on 02 May 2007, 13:11:50
Hi,

When i needed a crankshaft sensor i only had my Engine number and not the part number, in the EPC it does not list the engine numbers against the sensor, the nice Vauxhall parts man had a look at his old microfiche parts catalogue and it is listed there, so see if you Vauxhall dealer still has one, unfortunately I left the piece of paper with the cut off for the engine numbers in my last Omega when it was sold.

Frank.

Either failure mode is possible...     Mine played up with poor starting, showing a code 19, so I changed the sensor immediately on advice from here.  Result - starts as it should do and has done so ever since.  Others have experienced different forms of failure.

When you say poor starting what do you mean?  Did the engine turn over for a long while prior to starting for example?  I am interested to know as mine does not always start "on the button" as I feel it should.

Hi x25xe....starts fine normally on first turn ..just that it ran really rough like plug lead off..when accelerated it died and eml came on and car stopped..it did restart fairly easily but then gearbox light etc came on...that would seem to be "limp "mode...but today is running ok..so as davised will get new crank sensor ordered and replace as code 19 advises that is fault..will keep you informed on progress

Post by: x25xe on 02 May 2007, 14:13:19
Good luck with getting the correct part.  I have a trade card.  I don't know what kind of a hurry you are in but I could get it for you and post it it on if you like - this will add time before you can effect a repair though.

Anyway, let's hope that it is just the crank sensor and normal service will be resumed!

>> Did the engine turn over for a long while prior to starting for example?

Yep!  For me, it ran fine once started, but was sometimes very reluctant to start.  Mostly OK if it was recently driven.  When it didnt want to start it would crank like there was no spark at the plugs, but sometimes it coughed and splutted as it cranked.  Eventually it would fire.  But, it always ran fine after starting and never died on me after a successful start.  Never saw the EML on when it shouldnt be.  All problems vanished after crank sensor changed - I was showing a code 19.

Thanks x25xe..kind gesture which i really appreciate..have bitten the bullet and ordered one next day delivery from Vauxhall spares..anywaylets hope that with it replaced problems will be cured...just to be sure it was not a one off yesterday went to work in it this afternoon...wish I hadn,t...started fine and ran ok..pulled onto motorway and as accelerated it was like a kangaroo so eased of throttle and managed to get it to a steady 65mph about 2500 revs..this was fine until came off motorway about 40 miles later and at junction revs on idle were going betweeen 500//1500 so bit scarey on brake..when pulled away thought i had a lorry tied to rear end as acceleration was non existant..managed to limp back home when eml reappeared with gearbox warning ..paperclip test again revealled 19..so atleast it is consistant..suppose i was pushing my luck driving it anway..but seems really strange that with afault car will still drive...but for how much further..wont risk it in morning ..so day off and await postman

No worries mate.  From what you say it certainly sounds like the crank sensor.  I would not drive it until you get the new one fitted as you have indicated in you last post.  You can be sure that it will let you down if you do.

Good luck with changing it - just follow the guide and you will be fine.

Hopefully back on the road again very soon!

Sorry for delay in responding.

A 19 code on a v6 does signify a duff crank sensor.  Whether or not it would account for poor running is a different story, but it needs changing anyway.

When mine failed, it cut the engine, and the car coasted to a stop. This happened 3 times before I gave up. 2 of those times, I also got a gearbox warning.
