CEL doesn't turn off, during COLD SEASON

[tonzi]

My Honda ESI wont start unless CEL turns off, yes for honda ESI its normal. But my problem is it takes time during rainy season pag malamig makina specially in morning. would take 5-10minutes before it turns off. I went to a service center somewhere in banawe earlier to have my Computer Box scanned for P1200, But I didn't paid it though dahil wala naman na detect na problema, they checked next is the main relay sabi nung mekaniko ok pa naman daw but still when my car gets cold again it will take time nanaman. I ended up leaving the place coz they might just ask a lot from me hindi naman daw nila kaya gawin yung kotse, they need to check eveything and it will take time. so habang wala pa kong binabayaran umalis na ko haha.

help sa mga naka experience the same problem. What could be the culprit? and please any recommended electricians or mechanics? I'm just student so i really watch my budget buti naka free check ako dun sa pinuntahan ko kanina

thanks tsikot.

how about kung nakastart na makina? may CEL read pa rin?

EDIT: guesstimate ko ecu yan.

nope. pag on goin na makina wala ng CEL, just by turning it on it takes a lot of time before mawala yung CEL. I had them opened & checked my ECU. wala naman daw sunog, and i asked them if how will they figured out if my ECU is damaged. They said that they dont know how to check it. So saan ko ba dadalin na kaya tumingin at mag repair ng ECU? and do I have to consider other possible parts as well before dealing in my ECU?

help please.

actually kaya mo DIY yan kung may multi tester ka. kailangan mo lang malaman kung may dumadaloy sa mga capacitor, resistor etc. na koryente. tingin ko IC may tama sir. pwede naman rechip just in case.

kasi kung walang naread na problem obd, ecu ang ayaw magbato ng signal.

electrician sir ang kailangan. try reys electrical sa may cubao.

sir napa check ko na and na replace yung capacitor na corroded, wala namang pagbabago still an tagal pa din mawala ng CEL ko during cold start. chineck din nila yung sensors for temperature ganun pa din.

thats a cheap fix sa ecu.

EDIT: ay sorry sir hindi ko napansin ayaw pala start kung may CEL pa. anyway may redondo or crank ba kung try mo start na nakaON CEL?

hehe yes sir naka mura nga.. but still andun pa din yung problem its sunday today so walang mekaniko tomorrow ulit. medyo nakaka stress na yung problema. Yes may redondo siya pag CEL pero di talaga mag sstart i called honda. and they said this specific model 93-95 civic wouldn't start until CEL turns off so its pretty normal like 8-10seconds before it turns off. pero lately super tagal nya mawala. yun ang problema ko.

kung may redondo kasi buo yung electrical niya. sir best na maadvise ko sayo is kung may kakilala ka na kapareho ng oto mo. hiramin yung ecu siya then saksak sayo. kung nawala problem, chip na yan.

mahirap malaman kung may tama yung IC kasi micro chip na. bad trip nga problem na yan lalo na kung emergency pa lakad.

Sir! I have the SAME EXACT PROBLEM as yours!! Mine naman, pag nauulanan!! usually it takes 3 - 5 seconds during hot days, but pag naulanan, yun na.. it takes 5 - 10 mins! I already went to speedyfix and fixstop but they couldn't diagnose it because the problem won't show up anymore..

Nakakairita talaga to.. my car is 95 Civic ESi din..

kaya nga sir, super hassle yung gantong problema... nag try na din kami ng ibang comp box eh. ganun pa din.

something of this problem, the best solution is to have the pcm flash reprogrammed. there had been technical service bulltetins (TSB's) pertaining these symptoms.

Can you please explain it in layman's term? If we will have it serviced, what will we tell the mechanics? So far, they can't diagnose the problem since it's intermittent.. unfortunately, the problem won't show up once I arrive in the repair shop.

BTW Sir Tonzi, kagabi umulan po diba.. ayun, naghintay nanaman ako ng 10 minutes before I was able to start my car waaaaaaaaaaahhh!!!!!

[jick.cejoco]

it's usually the dealer who has the capability to reprogram your engine computer. sometimes, independent shops have the program, that is a specialty shop.

Can you recommend any shops here in metro manila that do this kind of service?

[jick.cejoco]

will there be a demand for this kind of service? i have asked this question in the past. the software is not cheap, will the demand pay for the software?

sir r1chmond, same here I had my engine diagnosed in Car zone in banawe wala din na detect. I had my one corroded capacitor replaced on my IC (computer box) but still same problem.. now I left my car on the mechanic just now. I'm gonna let them check the main relay and the sensors sa temp coz it seems na pag nalalamigan lang siya nagkaka problema.. I hope maayos yung problema natin. let's update each other probs thanks sir. medyo lumubag loob ko kala ko ako lang nagkakaron ng problema ng ganun, di pala ako nag iisa hahaha

Thank you din, I'll visit this thread regularly for updates. Sana magawa na auto mo para magawan ko na rin ng paraan yung akin. Thanks sir!!

I had my computer box/ic/ecu repaired kasi daw may mga lost.
They checked spark plugs and all relays and sensors.
fuel pump not working. it gotten now ayaw matangal ng CEL ko until now nasa mekaniko yung auto. haayz
badtrip po talaga yung gantong problema.

please identify the model year, engine size and engine family (nomeclature). will check for pending technical service bulletin or recalls for this specific vehicle
