    hi honda experts

    my fren's e-ek3 hatch got a problem.. it seems that everytime he open vtec (dunno whats the correct term) the check-engine-light will be turned on and will stay like that and wont turned off even after sometime. only when he switched off the engine and restart it will the check-engine-light turned off again. problem will re-occur if he open the vtec again. what could possibly be the problem? according to him, engine is actually quite new. transplanted last year. he's tryin to sell me the car but after having stumbled upon this prob, i have a lil doubt in me and am not sure about its true condition. could it be the wiring? or the engine itself? please advise. and oso, after vtec opens, i smell sumthing burnt.. is that normal? sorry no prior vtec experience... only drive iswara kodok before this..

    Thank you very much

    What engine is on the EK?

    You might need to check the error code on the ECU if its a B series.

    Google: vtec error code. Then you'll know what caused the CEL to appear.
    Burnt smell - normal. no worries.

    thank you lightningfiled and hattech-v for the inputs.. ok so ive googled and read about ecu error codes a lil bit and i will personally try to look into it assuming my understanding bout it is correct lar kan. later i will post the ECU status if there's any. and for the record, the engine is B16A.

    btw, anyone knows the address of Spoon Sports in SS3? i saw several people on this forum mentioning it. would love to have a look at the shop.

    even sometimes the error code will give you.. error.:biggrin:

    i have similar cases like what you've described, minus the burning smell.

    error code - knock sensor. - changed- after a few revving, light came on..

    after a few months, explained my scenario to my normal mechanic, and he asked me to check the vtec solenoid.

    guess what? the solenoid filter is blocked by the engine oil residue - very dirty:banghead:

    got it cleaned, and rev happy again, minus the check engine light, light.:biggrin:

    hope this will help

    thank you guys for the replies. to begin with, the car actually has no ecu.. so i cant actually post the ecu error code.

    i have actually decided to buy the car. In fact am in the process to settle the payment, geran, tukar nama n all that.

    i need to add that after having checked by a mechanic just recently, not really a honda specialist, he confirmed to me that the engine has no visible, bare or obvious problem known if not a more trivial problem resides in the engine itself/or unseen; which need further inspection. he oso added that it is most probably caused by the wiring which is a lil bit unorganized imho.

    i know i am probably making a big mistake here but i'll take my chances. (harga murah plus my fren willing to support me if really got problems, by giving me summore discounts hoho). Apart from the CEL, the car is good.

    pencalat: yes, vtec did engaged around 5++ rpm..around that; not sure d exact rpm but the "praaaang" did kicks in :)

    atkop: i am relief to hear that, well at least i am hoping that the prob is not (necessarily) caused by the engine. btw, mind to share with me which mechanic you go to?

    SC79: seriously? dindnt kno that..hmm do u have any suggestion where i shud go? im thinking of n1racing or amoil next.

    helmistaley: bro, kesian la the next owner.. huhu so, has he comlained to you yet? haha jk but gud to hear u manage to sold the car. no more penig kepala.

    To sum it up, i need get my wiring checked and fixed next. i would like to know which w/shop specialist in honda wiring? how much the cost would probably be (rough estimation oso can) so i can prepare my budget? will it be around 1K to 2K? if the work is KEMAS, CLEAN, AND THE RESULT WORK LIKE A CHARM then i dont really mind the price, err i think. :biggrin:

    thanks frens. Do reply ok..

    It could be something as simple as your minyak itam level low....might also explain the burning smell you get when high rev.... try checking the engine oil level...

    the cleaning process is quite simple really, even you can do it yourself:proud:

    take out the vtec switch asym, clean the filter (the "jaring-jaring" one), check the spring (can still "main" or not,) you might want to change the o ring/gasket etc, dry it up, and install it.

    i got it cleaned up at seri kembangan workshop- Rm 20

    haha sorry guys i apologies for my stupidity ughh :banghead:, how dumb of me, it was totally my mistake :banghead:.

    actually, i couldnt "find" the ECU so i assumed it was not there. smart eh? I have the slightest idea about ECU before apart from what i've googled and googled-pic it (and still tryna act like i got this in me hands). Again guys i am so sorry, hope u guys arent too shocked for my silly statement :rofl:. At least now i know vtec cant go without ECU LOL.. arghh i felt stupid.

    well i'd like to thank u guys for the inputs again.

    so i visited amoil the other day and get everything checked. Turned out it was my burnt ECU. yeah ECU, thats when i figured out the car actually have ECU. LOL.


    SC79: thanks, thats even nearer to my house. i would definitely drop a visit there soon. planning to get the car tuned somewhere.

    minivan: yeah, i serviced the car and the engine oil hasn't been changed for long time. changed the oil filter as well. and so far no burning smell. thanks :)

    atkop: i know not bout vtec switch asym but issit sumthing familiar to vtec solenoid? well thats what the mechanic suspected the culprit was but not and i saw it got jaring like u described.

    so i guess all my probs are solved for now.

    id like to know if there any rev-limiter out there dat can be installed? i over revved my 2nd gear the other day, (too syok layan the vtec and tak biasa with the quick rpm increase.. ya lar iswara before this slow nak naik RPM and can know from engine sound when to change gear but vtec i cant notice any sound difference, at least to me lar.) until the car cough (dunno how to describe it but the car was like tercekik makanan. slowed down and as if the car jumped a bit) so i quickly changed to gear 3. could i have damaged anything?

    thanks guys

    lol, the "cough" that you mean is actually jerk is it? That means ur car is having rev cut already by default. This will not harm ur engine if u do it once or twice, but dun keep on doing it lor although ur engine is with rev cut. Usually at 8500rpm.

    yup thats the one.


    for standard setup manual vtec normally "open or engage" @5800rpm, people sometimes change the airfilter to open pod and muffler (the loud one, 304 bodermax to "hear" the vtec sounds)

    think rev limiter is part of the ECU function?

    I'm also experiencing this problem.. Previously i did not have this problem.. But one fateful morning after joy ride from Genting there was this long stretch of road, so i engage vtec and stayed around rpm 7-7.5 for quite long lah.. Then the check engine light appears.. Being a paranoid person i stopped my car by the roadside, turned off the engine and let it be for few second/minute.. Turn back on engine the light is gone... Then engage vtec again, the check engine light appears...

    Ever since that day, everytime i engage vtec for at least 3-5seconds... the check engine light definitely appears... But if i turn off my engine and start again, the light will disappear...

    Haishh i also don't know what is the problem
