Title: EML Stays On Engine Runs Slackish
Post by: OpelJay on 20 February 2012, 20:15:35
Hello you good looking ppl :D lol

Basically over the last 2 days ive noised my eml has decided to stay on... but as the car is still running i don't see it it been a big problem...

but i have noised that there are tremor like systems when driving along. earlier i started her up and to my delight it turned off when driving it felt like there was a spring in its step felt much better, sadly soon as i turned off and returned with my take out it was back and same crappy systems appeared again.

i have a hunch that its a lambda sensor but want to see what ppl say first thanks for your feedback :)

13 Oxygen sensor Open circuit

your lambda dont turn any signal to ECU..
 
check wiring first..

cool does that mean i need to unclip it then reconnect or is this normal meaning to change it?

thanks again ;)

never seen a completely dead lambda (ie no signal)..  even very old lambdas after heat up , they return signals.. :-\
 
but for your info, recommended life for lambdas 100 K kms  after that period they slow down and degrade performance..
 
so first check the sockets and wiring imo..

did you check wiring..   also you can use an ohmmeter/voltmeter to check

well i was thinking its only just scraped its mot emissions and the car has done nearly 125,000 so maybe time for a new 1ant really got the tools to check the old one plus im in the army and im based out here in Germany so not like i can nip round me muckers just need to find a cheap 1 at the right price :)

code 13 is not crank sensor.. but if its limiting the revs, thats another problem..

I've lost a bet with exactly same symptoms :-\  against Mr DTM.. but probably that was a different engine..cant trust my memory now :P

Is the fault on petrol or LPG.

The lambda fault code be thrown when the ecu hits the limit on its adjustment value based on lambda readings, been seen a few times with LPG setups which are not at optimal settings

lambda fault on lpg is something normal .. I think question is asked for normal fuel

besides for lpg the codes must be O2 sensor voltage low or high..

Ok I'll change the lambda sensor seems strange now on 2 occasions in 3 days the light went out and worked fine then it comes back again hope I don't waste my money the lambda sensor ant cheap :(

I don't really have a volt meter and don't fancy been ripped off by the garage funny thing was I removed the cam shaft sensor plugged it back on then the light went out drove mint! Got back then the light back on ;( tryed messing about again a few times but no luck seems strange if can go from been crap to ok then mashed again???

Redo the paperclip test, and post up every code before going further...
Title: Re: EML Stays On Engine Runs Slackish
Post by: cem_devecioglu on 21 February 2012, 21:27:18
generally the open circuit is caused by broken wiring/socket problem :-\

At this stage, I'm not convinced there is a 13 code ;)

Lets wait for OP to recheck the codes...

Ok tomorrow in working on the tanks so I'll get under me car and check the clip for the lambda sensor then I will do a paper clip test again and let you know all your feedback is most appreciated :)
Title: Re: EML Stays On Engine Runs Slackish
Post by: OpelJay on 22 February 2012, 14:48:26
ok the code is saying now 10 flashes followed by 3 flashes followed by 4 flashes then ten flashes again then starts over again hope this helps cause the car was running like shit this morning :(
Title: Re: EML Stays On Engine Runs Slackish
Post by: cem_devecioglu on 22 February 2012, 15:18:26

When my cam sensor was on the way out it would do this.  Cleaning up the plug and socket with some electrical contact cleaner kept it going for a couple of weeks before the light would come back on.  Eventually, the period of working got shorter so there was no option but to change the sensor.  Once that was changed it was like driving a different car!

yes, tried 2 i got of ebay.....neither worked.  :o  Bought genuine.....after fitting light went out on first crack of key. :y  Had to do a little wiring though as it was the modified sensor, as opposed to the older square type  one fitted originally.

If you go for a second hand one, or a cheapy ebay one .. make sure you buy at least 2 if not 3  ..as you will be replacing them on a regular basis.

The advice to fit only new, genuine items is not from some predilection to Vx parts . but because it is a known that the others simply don't work.

Your money, your choice .. but unless you like changing them regularly, and you have a good recovery plan, there is only one way to go IMHO

I thought that a non-genuine camshaft sensor couldn't be that bad so that's what I originally bought.  I should have listened to the advise on here as it just didn't work at all.  I had to send it back for a refund and buy a genuine one anyway.  All I got for my pig-headedness was a lot of hassle and delay.

Get a genuine one, or you will regret it.

Only cure is a genuine Vauxhall cam sensor replacement. It may cost a lot but will save you a lot in the long run.

does it play up on petrol or gas if it plays up on gas you need to spray carb cleaner into injectors-had mine play up -cuts out/rough idle popped n banged tooo  :'(  undid gas feed to injectors and loads of cleaner later-result.  :y
