engine management - the lights back on ?
« on: 06 November 2011, 10:29:58 »
Hi guys,

I put this initially with my old post but perhaps it should be listed as a new one

So 20 days after the light went out as Im driving home from work last night it comes back on.

Armed with my new found knowledge I have done the pedal test it appears to be showing 2 codes one after the other :-

0170 -  fuel trim bank 1
0173 -  fuel trim bank 2

ok thats all the information i have as usual i bow to your knowledge so please help

Strangest thing is if it all is really fuel and mixture related why is it not showing in how the car runs.  If she was coughing choking back firing and running like a pig i could understand it but nothing.  I gave her a bit of a blast on the way to work and not a thing.

help !!!!

I am beginning to wonder if the sensors are the problem (Lambada)

It seem strange that the light went out for over 2 weeks without being re-set and then suddenly comes back on again ?

should i be investing in a reader that can reset this

It would be nice to see what the trims are doing, and also see if the lamdas are switching properly.

Does anyone near you have access to a decent code reader with live data?

Is there a common cause that would effect both fuel trim banks at the same time without effecting the general running of the car

Did light coming on coincide with refuel or low fuel?

Yup .. limited Live Data is possible ... in Wootton Bassett and available for the rest of the day... I think you have my number from previous PM ??

If not today then usually Mon-Wed after about 1730 or any time the other days ..depending on what else is occuring :)

Happy to try and help whenever it suits

thanks i really do appreciate that trouble is im working such obscene hours at the moment, even today goes with the job im afraid.

Im toying with a couple of ideas :-

1.  buy myself a reader that can also re-set but on a limited budget but it will have to be acceptable to my derivative of Omega.

2.  i know someone who does mobile diagnostics but will he accept the codes i give him as true without a full diagnostic and all the charges that incur
plus side he comes to my house/work
down side costs loads

If you decide to get a code reader .. you need an OBD2/EOBD for the 2.6/3.2 versions. there are many cheap copies on e-bay .. beware they are cheap and copies and often don't work.

I have a maxscan GS500.. which is no longer made there are some very similar on this link

http://www.talktomycar.co.uk/products/codereaders/codereaders.htm

The 509 is the latest version of mine. If it is as reliable and easy to use then it's good !!

Seems a lot at £90 I know .. but a single visit to Vx is £70 + VAT... once you have this it can live in the boot and always be available, especially for the day you get the 0420/0430 codes .. it's not a case of "IF" you get those .. but "when".

There are other types available ... those that are sold as ELM232 require a laptop as well as the device, not "user friendly" IMHO.

Good luck, and if you need to plug into mine .. just phone :)

Do you have a laptop ?? with USB sockets ?  I have an ELM327-USB device that I bought before I got the maxscan. It works but is not "user friendly" IMHO .. which is why I bought the maxscan. If you have a laptop you can have the 327  it's just sitting here doing nowt. I even have some additional software somewhere .....

It will read/clear engine codes and put the light out ... but if memory serves live data was tricky/poor.
