umiilaw ang check engine light

**blackgli** · November 12th, 2009 03:11 PM

bro yung sa radiator fan mo dapat iikot lang yan pag nasa mid na temp mo. usually mga kotse ganun. kung umiikot ang radiator fan mo pag start pa lang ibig sabihin nyan basa ang terminal ng radiator fan mo. i-check mo yung wire harness ng radiator mo tapos patuyuin mo lang pati na din yung relay box sa engine bay. meron yan radiator relay baka shorted linisin mo lang.

Sa ECU problem mo kung naka-ilaw may problema yan. Ganyan din nangyari sa friend ko, kinalas lang namin ang ECU nilinis tapos hot-air then salpak ulit. Ok naman nangyari normal naman kotse nya ngayun.

goodluck!

Bago po ang ECU nya, kaya di na kilangan ng linis.

oopppps sorry na skip ko basahin na bago ecu. my bad! hehehe

kung bago ang ecu tapos naka ilaw pa din, may sensor ka nga na nagloloko. I suggest linisin mo lahat ng sensor sa engine bay mo pati na din mga connectors nya pero start with the radiator fan since yun ang nagloloko. DIY mo muna yung paglilinis ng mga connections madali lang naman yun, sa relay box linisin mo na din. Gamitan mo lang ng Contact cleaner yung mga connectors & relays. Pero ingat lang wag sobra ang gamit sa contact cleaner.

peace!

mga bossing napa check ko na sa mikaniko... savi ok lang na naka ilaw ang engine light kaysa sa nag bliblink tama ba savi niya?

and tungkol sa radiator fan may mga nadali nga daw sa mga relay nung kotse and pati yung sa wiper hndi gumgana... pero mamaya bibili ako nung mga pinbibili niya na mga fuse ata yun ,,, medyo confident naman ako kasi sa casa din siya nag wowork and nag sesetup and detailing din siya ng mga car na pang raising sigurado alam naman niya ginagawa niya.. family friend siya... comment suggestion????

Maybe he is a very good mechanic but not to your car,
He did not even know how to find the possible caused why the check engine lights still on.
The only thing or device can scan the codes ay nasa TOYOTA CASA.
Have them check the codes, ask the list of the results .

A little advice,
Don't give 100% trust to your mechanic even he is your brother, your father or a family friend unless he is a Toyota trained mechanic.

A lit CEL (blinking or otherwise) is never "OK". You need to have your casa diagnose it. Using a diagnostic tool, they can pinpoint or at least narrow down the cause of the problem.

When the CEL is lit, it usually means a problem with the emissions system. This usually happens when the ECM encounters a sensor that has a reading that's out of range. As a result, the ECM goes into a pre-programmed state (aka limp mode) and ignores the reading from the faulty or out-of-spec sensor. That said, the engine will somewhat lose efficiency (ie. the fuel system may default to open loop and the A/F ratio set to rich, etc. to protect the engine).

yes tama si xda2jojo. Hindi normal ang naka ilaw na "check engine"

have your radiator & wiper repairs muna kung working na check mo ulit kung naka ilaw pa ang check engine. Sa tingin ko may fault somewhere around your radiator sensor or relay lang talaga. bro kung fuse ang sira hindi gagana ang radiator fan mo kasi no current can pass through fuse kung busted yon. kung relay naman gagana yan or sometimes hindi. ang purpose lang kasi ng relay is "on & off" mode "open & close" state lang function nun.

pakicheck na din yung ibang relay na nasa relay box sa engine bay baka nabasa din yun...

CEL = Check engine light
ECM/ECU = Engine control module / unit = "Computer box"
A/F ratio = Air/Fuel ratio

No offense, but if you can't figure out what they meant on your own, you better take your car to a reputable mechanic.
