hi peeps.just a quikie.on the way home from work last night i was accelerating (not thrashing but firmly) down a slip road,i turned my head back from looking behind to find a gap and just caught the engine check light flash 2/3 times.there wasnt a pattern to it as i only just caught it in my eye.

i backed off but the engine still sounded sweet so for the next 2 miles i tried to replicate the conditions but all seemed good.when i got home i plugged in the connectors but only got the fan cycle and a constant flash of the light.am i right in thinking a constant flash means no fault codes stored??

if so what could have caused this temporary flash when driving? my01,bug.uk wrx,basic mods,80k on clock.thanks guys.

not sure mate i have an 02 bugeye and mine is on constantly now not sure myself

plug in the two green plugs hanging under the steering column,its a bit of a bugger sometimes to get to them,then turn ignition on so dash lights up,then your light will flash in a particular pattern ie-3 long flashes + 2 short flashes.this pattern(fault code) will cycle over and over until you turn ignition off.note tho that you may have more than one code show up.when you have that code post your results on here and someone will tell you what is wrong bud!

e.g. - not i.e.

i.e. = that is (something specific)

e.g. = for example (one of two or more examples/scenarios)

hi just tried that and it just flashed fast to fast for me to count (constant flashing) any ideas any one what the code is and whats wrong. please anyone.

milliemoo

if im right in thinking this means no fault recorded which should be a good thing!However if you have a light on all the time then something isnt quite right!maybe someone will be along to help soon!!

Adam Davies

ok thanks anyway. i pluged the green plug in under the steering column turned the ignition on and it started flashing constant but to fast for me to count

The "okay" code should flash on and off evenly every second, continuously i.e. on for 0.5s; off for 0.5s; on for 0.5s; off for 0.5s, etc....

So not so fast that you couldn't count each on/off pulse!

Adam Davies

yeh thats it on and off in 1 sec so why is the light still on ?

i think this sounds like the same thing that happened to mine.. put foot down and engine management light came on at 6k rpm.

stays on permenantly now. checked code. it says poo31 ho2s heater control circuit low bank sensor 1.

cleared code and it came back on within 5 mins..

stays on now.. what could this be.. lamda probe covered in soot? its a decatted 02 bugeye.. drives perfect, no different..

Adam Davies

i will have to take it and get it plugged in and find out i think.

Adam Davies

does anyone know what the fast flashing engine light means as discussed above.

If you mean same time period pulses for on and off (i.e. 0.5s for both), then it means "all clear, no faults logged."

i had a cam sensor problem on my bugeye everytime i booted it the managment light came on anyway disconnected the cam sensor cleaned it and plug reconnected no probs since

Adam Davies

Adam Davies

sorry fellers ment to say thanks for your help.

Well, if your engine light is on, it's because it's sensed a sensor 'issue'. You need to do a fault code check to see what's up. Normally you would have to replace the offending sensor, do a reset and the CEL should be gone. But you can do a reset regardless and, hopefully, if it's an only an erroneous CEL, then it may just extinguish and not come back............

hiya joz i was told the bugeye model in particular do suffer from tempremental sensors is that right

Adam Davies

I think so Nick - moreso than the Classic (if the posts in Gen Tech are to go by...)

Adam Davies

hi again tried resetting again and no joy by the way i posted as a new thread yesterday with engine codes explained it was a link to a site called.... Scoobypedia | Trusted knowledge for everything Subaru | Scoobypedia / Scoobypedia i hope this is of some help to some of you.

milliemoo

thats sods law that is.as the thread start explained i had a flash of my cel and not had it since.

until today that is!!!i now have the same prob as adam in that the light is on permanently after a little spirited run as id done the last time it came on.

however i think i know what is causing it.im sure i can hear a little blow/chuff from up-pipe to turbo or maybe turbo to down pipe.not sure exactly as space to hear it is limited.im for the up-pipe.this then gives my lambda a false reading and throws a cel.does this sound logical???

would this be a cause for great concern as i need to use the car daily until i book a day off to do it (soon).oh and disconnecting the battery didnt reset the cel!! help appreciated

Adam Davies

i tried the disconecting the battery thing aswell didnt work for me eather. what you said makes sence to me mate i had just changed the gasket on my down pipe just before the light come on now i think about it, never even occured to me till now so think i might pull the lambda out and give it a clean see if it makes a difference. best of luck with yours let me know how you get on.

For what its worth, I am having a similar problem, certainly blowing just below the turbo and the CEL on.

This technique doesnt work on newages Joz. Needs to be read via OBD scanner or laptop & cable.

Oops. Sorry duncan - didn't see OP had a '01 Bug.

I must stop assuming people have Classics! lol

milliemoo
