Hi,
Recently my car has started to judder, quite violently but briefly at speed, the Engine Managment light comes on, it then drives fine (slightly more sluggish ??) for a couple - few minutes and the the light goes off and all is well again. It will then happen again at any speed, but not at all (maybe just once...) when stationary and idling.
Took it for diagnostics and it reported P0110 - Intake air temp high voltage and P0100 - Mass air flow sensore low voltage.
Replaced the MAF unit (£250....) , but it stayed the same and reported the same faults. Took back and a 2nd MAF was fitted (FOC) in case a faulty one had been supplied, but still the same and reporting the same faults.....
I have considered cleaning the throttle body and all associated breathers etc, but I thought that this was more associated with stalling / cutting out at low revs.... (have previously, 2 years ago, experienced this and solved it by a good clean out.)
Has any one experienced this and got any ideas ?
Thank you in advance,
frustrated.......

can you confirm engine code for me if its a x18xe1 then they are prone to loss of earth and there is a mod/rework for them
|
Hi Topbloke,
Yes it's a x18xe1. This sounds very possible..... I'm not aware of this and any information would be great!
Thank you,

well its is basically suppling a new earth wire for the maf sensor and the temp sensor. the original wire /earth point via the ecu fail , you would need to find the yellow wire from the maf and the brown cable from the temp sensor these wire join together in the trunking above the injectors, remove the cover, find the wires and splice into them a new wire, run this through the trunking and out near the ecu which is bolted to the engine, put a tag/eye terminal on the new bit of wire and using the earth wire bolt that is on ecu as a earth . this is a known fault and your local dealer should be aware of this, it is field remedy 2033 hope this helps
|

this could also be an egr fault
|
Hi Top bloke.
What sort of fault with the EGR ? Can this be easily tested ? Can it be easily replaced ? Where is this ?
Thank you for all your ideas, I'm getting rather annoyed by dealers not being able to help....
Thanks,

I'd go for the first idea that TB came up with; I've seen that pair of codes many times when the solder on the pins of the ECU plug cracks. [Who thought that it was a bright idea to mount an ECU on the engine....?]
It is sometimes possible to get the ECU repaired by people like BBA - depends on the type and year.

Hi TB and screwloose,
Thanks for the ideas. I think I'll give it a go over the next couple of days.
Thank you,

>>[Who thought that it was a bright idea to mount an ECU on the engine....?]
I don't know if Cummins [Celect] were the first, but they were definitely doing it long before Vauxhall.
As you might imagine, I think the principle is a good idea. For a while there will be some teething troubles, but once the more stringent engineering requirements for mounting an ECU on an engine are understood and followed through, I think you'll get better reliability. There's a good saving of all the wiring running through the bulkhead, and it makes for a much 'cleaner' engineering interface between the powertrain and the body.
Although subjecting the ECU to the engine environment will provide it's own challenges, these can be understood, controlled and overcome in a systematic way - interface problems where one engineering team has to negotiate with another for space and mass alowances are an area that's rife for error - the interfacing is different for each model, each engine type, and even down to what other options the customer specifies.

the egr problem tends to be on light throttle 4/5 gear sort off shunting/surge through the vehicle, not a missfire as such but could be confused, as such this fault rarely brings up a fault code on this engine but with the two codes that you have posted i would certainly do this mod, if it don't fix the current problem it will save you doing it later lol !!!!!!!!!!!
|
Hi - Topbloke,
Today I did this mod partially with, apparent, great success!
I found the yellow wire from the MAF easily.
But wasn't sure where the temp sensor ( I thought it was part of the MAF ??) was and therefore couldn't identify the brown cable. In the trunking there were 2 brown wires and therefore I didn't take the risk.
However I did as you said with the yellow wire and all seems good. EM light off straight after start up and driving well !!
Do you think I should also do the brown as well ? If so can you please tell me where the Temp sensor is. Or should I just leave it as it seems okay ?
Thank you very much.
Sutters.

sensor is the for the ecu but is a coolant temp sensor front of head offside near top hose two wires 1 blue other brown remove trunking and add a wire from your new one to the brown making it a y shape Regards TB

We had a problem that the engine light was permanently on and the car shuddered and surged all the time. After spending a fortune on a long list of sensors etc. we read this review so thought - nothing to loose. Fantastic. The light went out and the car runs smoothly.
How come the main dealers keep selling you the bits and charging to tell you the codes and dont know (or say). Many thanks.

For months now i have had a problem with my vectra.
Low revs-cutting out engine warning light permanently on and just sound crap judery etc..
I have had diognostic checks and replaced the mas airflow several times.
The warning light never went off even after changing to new MAF.
I have been going out of my mind with this and was even going to sell my v-reg vectra CHEAP,Then i came acros this thread and read topbloke's fix for this.
I followed his fix and did the new wires.
The problem was sorted and the engine light is now off and the engine is running great with no loss of revs or cutting out.
I would like to thank topbloke for taking the time to write the fix in this forum and saving me more cash.
You are certinaly a topbloke
THANKYOU

i assume the virtual cheque is in the post as an asside this is a field remedy from vauxhall, glad to be off help
|
|
i will ask garage to do this for me as i have same problem with mine!! Has been ongoing for 3 weeks now and still not sorted.
|

|

This works great - thanks topbloke
found the cable from the MAF with ease and the brown cable from temp sensor. followed both back into the trunking behind the injectors, stripped the wire from both in a small area (without cutting) and joined them then soldered a new wire to where the cables joined. connected the new wire to the 8mm earth on the ECU and all works perfectly fine, EM light off, No Stalls, No Juddering.
After months of sluggish driving im pleased i found topblokes advice

I have reciently had this problem my self,car misfiring juddering cutting out light on & and off. brought my w reg 1.8 vectra dec 08, when i had it mot'd may 09 i had the car serviced and the cambelt changed,the car was fine up to this point, when driving home engine light came on,went straight back to garage,after leaving the car with them for a few days they changed the maf sensor, but no better tried another 1 no good fault codes saying air sensor & air temp sensor. then i went to a vechical electrical place, they siad 99% it was my ecu and will cost £350 to have repaired,this had been going on for 5 weeks now,after phoning and asking around, i was not convinced it was the ecu . after reading this forum i tried re earthing the yellow wire on the maf sensor, i did this by splicing into the wire just under the maf sensor and earthing it to the enging about 6 inches away where there is a earth lead using a 8mm nut,so there is now three are nuts on this earth point,this took about 30mins, so far so good it as now been a week now and the car i running fine again, 5 week of hell because of a bad earth, weather i was supposed to use this earth point but so far it is working,i had spent £145 up to this point, which would have been a cost free fix.......!!!!! just hope this post could help others in the future.

Just had the same problem. Went to Vauxhall garage and got a printout of Field Remedy 2033. I have scaned this and can send it to anyone who needs it. I don't know how to put it on this site. Had an auto electrician do this for me and then drove for about 10 miles so far so good, better response, no lights or judders so far (fingers crossed). Vauxhall garage said probally ECU fault even when I told them what I wanted done said would take 1- 1,5 hours labour, rubbish topbloke was right V. easy. Took 1/2 hour with tea break. Also windows didn't auto shut but hold down button for 10 secs worked.
If you live near Bristol, Earlam Auto Electrical are ace.

Hi just reading you messages. IO bought an astra last week with the light on had it tested and came back with fault po110 po100. So bought a second hand maf sensor. it ran ok for a few hours then the light came on and its sluggish again sound like i need the field fix done. any chance you could send me a copy please. Dan

Hi saintadz can you send me field fix, I have been told exactly the same things need a new MAF, changed no better, need a new ECU, sent this off to be tested, came back nothing wrong with it. Not much of a car mechanic but the lad who has done the other bits says of I can find a fix he will carry it out. Please send to r.way@pgs.org.uk
|
|
Sent you the fix, worked a treat for me. No faults since. Only cost me 20 quid to get it fixed.
|

Have done the deed and the car is working perfectly again. Wish I had discovered this two months ago before splashing out on new EGR and MAF. Do not need the printout just follow info by Topbloke above. Dead simple fix.
|
|
Any chance of getting the fix info. Got the same problem, the warning light actually stayed on long enough to get a code !! Would be great to get rid of this one.
colin324@hotmail.com
Thanks

Hi can you send me the info too?
tonyh@webra.co.uk
I tested the yellow wire with a multimeter to the negative on the battery and it showed as a live wire carrying 12.5v when the engine was running.
is this safe to connect to the earth on the engine?
thanks
|
|
engine is X18XE1 by the way
|
|
I do not think you should put a 12v+ to earth unless you like blown fuses or fireworks.Yellow is an ignition switched 12v supply you will find another feeding your radio.There is talk above of making a Y circuit you are not getting confused are you.
|
|
it appears i am, posts above say to splice the yellow wire and connect to the earth on the engine,.. i dont know what i need to do..
|
|
help with step by step pleeeease
|
|
I cannot help you but if you put a positive to negative it will go bang.

sounds like some thing i am having trouble with. car spultters, runs bad. it has now sat on my drive for four months. engine light was coming on, . had loads of work done. arhhh. does the wire thing really work. i have some one coming from to tell me what i can get for the car, weighing it in price.

Having all these symptoms in my 1.8 Vectra too.
Changed the usual suspected sensors but no luck.
Diagnostics say crank sensor yet ive replaced 2 in succession (didnt trust the first was a good one despite it being new).
Things are pointing to the ECU but after reading this it makes a lot of sense!
Its unlikely my car would start at all if it was the crank sensor and after leaving my parents house tonight it ran like a dream for about 500 yards and then went back to being sluggish and jumpy again...
Before I take it in for the customary ECU change I would like to beef up the earthing too... Any chance of a copy of the way you did this too please Sir?
Ive a sneaky feeling this could well be my answer also..

If everyone who needs help with this fix looks on any of the Vectra forums and does a search its all there.

Vectra-sport
There may be more !
