Hi,
i'm new to the forum and i need some advice please.
i had my accord for three years now and there was no probs with it.
always serviced on time with honda parts and 0w30 oil.FF was changed about 5K ago for genuine part as well.

now here's my problem.
yesterday started her up and when was on idle engine just cut off after about 10 sec.
since then this happend to me 2 more times and it seems to happen only when cold.
and also when i rev it up a bit doesn't happen neither.
and two of the lights flashed at the same time GLOW PLUG and ENGINE MANAGEMENT.

please need some help,
any ideas guys
 
Hi Mike, welcome to TA. But I wish it was in happier circumstances!

If the engine management light is on, then the ECU will have recorded an error code (DTC). You need to get access to an OBD2 reader and have the stored code read off, then post it here so we can make informed suggestions. Otherwise, we can only guess.

Many TA members have bought their own readers... they are cheap and readily available. If you lived near me I'd read it for you - if you put your specific location then maybe someone near you might offer? Or take it to a garage to get it read?
 
thanks for reply.
i have ordered the code reader myself and as soon as i'll get i'll have a look at the errors.
i'll post the codes ASAP.
 
got the reader today.
one fault was found but didn't show the error number.
anyway i have erased it and at the minute it works fine.
 
hi all.
the problem is back but this time it cutted off while driving.
also noticed smell of fumes at the back of an engine when bonnet open.
any ideas guys?
 
The fumes are almost certainly caused by a cracked exhaust manifold... this is a common problem (mine does this). However, a cracked engine manifold wouldn't cause your cutting out issue. I don't properly understand how you found an ECU error, but the reader didn't give you the number - sorry to ask, but are you sure you're using it correctly?

Can you get the engine to restart? Did the ECU warning light come back on? If so, have you tried again to read & delete the code?
 
hi,
i know its strange but yes im using it correctly.
it shows me that there is an error but no code comes with it.
i can delete it but it does the same and comes back.

i noticet today that if i leave the error it seems to be running as normal but as soon as its deleted engine is cutting off.
and theres no problem to restart.
starts at the first turn all the time.
 
came back from honda today.
they found temp fault with ecu and that aparently was causing my problems.
wait and see.
also the said my exhaust manifold has a crack and qouted 680 for repair.im out of warranty by 2 months,great.
the wouldn't do it as a good will cos of not full hond service history.
 
Does temp mean temperature or temporary? Either way, I guess it's likely to play up again!

...A faulty ECU would explain the earlier confusion.

EDIT - Maybe the exhaust manifold won't get any worse (mine hasn't over the last few years).
 
yes i meant temporary,
but they weren't able to say what was causing the fault?
 
I can't imagine how you might fix this, short of fitting another ECU. They don't go wrong very often, so I guess a secondhand one would do the job. I don't know how much other 'coding' would need to be done to make it fully compatible with the vehicle, but ideally the injector calibration data would need to be programmed in (the ECU is otherwise self-learning). Not sure about the immobiliser side of things though - hopefully someone else can answer this?
 
I've never known an ECU failure in these cars yet mate. Sounds like they're just guessing because they don't know how to use their own tools properly! Cutting off like that is most likely a fuelling issue, either a blocked or incorrectly installed fuel filter or even a leak in one of the lines perhaps. Take it to an independant garage.
 
Listen to F6had. Since Ever since I joined this forum I don't think he's missed a beat in terms of diagnosis. He has a freakish sixth sense for this. He seriously knows his Onions. Take it to a trustworthy indy as suggested and best of luck with it.
 
^^ thanks bud, but I'm also only really guessing.. but I'd say my guesswork is no more or less relevant than theirs. If a car goes to the main dealer with an engine management light on, the least they should be able to tell you is what the error code relates to!!

I use the HDS every day, I've never seen it give an 'unknown' error of any kind. Cutting off could be anything, a knackered MAF, MAP, EGR sticking, fuelling or simply a vacum pipe off somewhere.. For stuff like this, I tend to either have a go myself or use one of my trusted mates who I know will not fob me off.
 
thanks for replies.
and guess what, problem is back.
took the car to diesel specialist and was told it might be sensor on fuel pump but he will only do the job when i'll get it confirmed with honda.
so how can i if they can't tell me what the problem is?
oh,and i've cleaned MAF and few other things but not yet the EGR.
try over the weekend.

There isn't a sensor on the diesel pump, the connector on the side of it is the supply to the pressure control valve, which is an electric solenoid - yes, this could be faulty, but you would then get a P0088 (rail pressure high) or P0087 (rail pressure low) error code (DTC) recorded and stored in the ECU.

This has always sounded like an odd problem, especially as you seem to get the ECU error light on with no stored code. In post #8 you did say that Honda have already diagnosed an ECU fault... despite it being very unusual for these to go wrong, I don't think you should simply ignore this, as complex electronics units do go wrong now and again! Although often this turns out to be a connector problem (so I suggest you at least pull off/push on the ECU connectors to see if that sorts it out).

When you took it to Honda and they told you the ECU was faulty, did they quote you for a repair? Did they use the Honda Diagnostic System? Did you get any sort of report from them?
 
had a second visit at honda today.came out with internal ECU error.
ECU was reseted and apparently latest software was istalled?
anyway was told that if this won't help then need to replace the ECU @ about 1000.


Is getting hold of second hand one an option?
can it be reprogrammed?
and is there any difference between ECU for pre-facelift and facelift?
cheers
 
You can definitely use a second hand one, the entire 2003-2008 range was fitted with the Bosch EDC16 ECU. You will need to have your maps transferred over and the keys recoded. I've never done ECU recoding to another car but I do believe my HDS can do it.
