Why the "Check Engine" light comes on?

[eign]

Ask ko lang possible reasons why "Check Engine" light comes on? I'm driving a 97 Corolla GLI (matic) and noticed that the "Check Engine" light turns on after a few minutes of driving. I haven't noticed anything else odd though. Pina check na sya sa talyer and ok naman daw, wala daw problema, they suggested na "pundihin" na lang ilaw kung naiilang ako. Tama ba yun?

Can anybody recommend a trustworthy shop within Las Pinas/Alabang area?

ewan ko lang kung applicable sa iyo.. pero kasi itong van namin ganyan din... 2003 dodge... tapos nuong unang dinala ko sa dealer kasi umilaw nga ang check engine, ang nakita nila - di nakasara ang ang gas cap ng mabuti... eh di isinara ng maayos... tapos after a few months ilaw ulit... balik ko na naman... ganun pa rin nasingaw daw ang amoy ng gasolina kaya nag-light up.. eniway, pinalitan ang gas cap... other than that okay nman ang lahat... hth

Check engine

All modern vehicle have a computer or the ECM (Electronic Control Module) that controls the operation of the car powertrain. The main purpose of this is to keep the engine running at top efficiency w/ the lowest possible emissions.
Your car computer system has self-testing capability when the computer sense that there is a problem w/ some of the components it stores the correspondent trouble code in its memory and lights up the "check engine" or "service engine soon" to tell you that there is a problem and needs to be looked at.
Bring your car to the dealership or any reputable garage(shop)to hook up the scanner to the car computer to retrieve the stored trouble code(s).

when the check engine light comes on, nag-iiba ba ang takbo ng makina? Like parang pigil or sakal? If not, baka may mga loose or maduming sensors lang.

As for the suggestion of that talyer that you consulted, that was a pretty stupid suggestion and obviously they don't know what they are doing. Kaya nga may CEL (Check Engine Light) eh to warn you that something is not right with the car.

To be sure, you can go to Toyota Casa and have your ECU scanned for errors, sa Mitsu casas ballpark figure is 600-700 pesos yata ang ECU scan, I don't know about Toyotas' rate.

Eign,
Does your corolla have a computer box?
If not, belt or alternator seguro yan.

low in oil? never ever return doon sa talyer na nagsabi na "pundihin" yun ilaw ng check engine mo....

[CVT]

When the "check engine" light turns on while driving, the manual typically says you have to bring it to the manufacturer for check-up.

There are a few reasons why this light turns on.... One of them is that the computer box could be defective or intermittent, which means that the right mix of air and fuel is compromised. In some of the vehicles, it automatically puts the vehicle into limp mode,- meaning that you can only travel at low speed..... Do not ignore it. It could mean/result to bigger worries.

Hehehe, natawa ako dun sa suggestion na "pundihin" na lang ang CEL. Old school mechanics malamang.

Kung namamahalan ka sa casa, just go to any talyer na may OBD scanner para malaman kung anong error code ang binabato ng car mo.

Pero, its worth a try resetting the ECU, since sabi mo naman you haven't noticed anything odd.

[shadow]

sana sinabi mo rin sa mekaniko mo na pundihin mo rin yun mata niya....hehehe
dumaan ka ba sa baha bago nangyari yan?

[mazingerZ]

Better have your car checked muna with CASA or shops with OBD scanners bro. I'm sure there is a reason bakit umilaw yan. CELs only light up prior to start-up ng kotse, and namamatay after ignition if everythings okay. Hanep din ang mekaniko mo hehehe. . .

Tsips!

Can you suggest any shop that has these ECU scanners?

TIA!

Speedyfix has one.

[Galactus]

Sa Speedyfix alam ko meron. Check his sig for the address.

But if you're the DIY type, then check this ad... http://www.sulit.com.ph/index.php/vi...ext=151#paging

Hmmm...mura lang pala ang OBD scanner.

[t2erns]

don't reset the ecu unless you know the reason ng MIL (malfunction indicator lamp or check engine light) if it's blinking then iit needs scanning asap there's active misfire, if it's steady not serious enought to kill the cat, but still you need to scan it. try searching the net and you'll find how to read codes by using only a small piece of jumper wire.

[tibo_3rd]

have your oils checked: transmission, power steering, brakes, engine. there might be a leak somewhere.

i too had the same thing. the check engine light was on during different occasions. i brought it in and they saw a leak in the power steering column. had the seals replaced temporarily until i had the whole steering coulumn assembly replaced. and so far it doesn't light up again.

[Dieseldude]

Check engine light or "MIL", or malfunction inlicator lamp warns you that the ECU has detected an engine fault.

You can bring your car to a Toyota service dealer for fault scanning. They have the necessary scan tool to detect and identify the specific fault/s.

MIL should not be disabled for obvious reasons.

pa diagnose mo na lang po using a computer sa casa.mura lang naman and accurate pa... mahirap mangapa pag ganyan dahil electical and it involves ECU.. also check your manual din kasi sa honda may self diagnose feature na pwede gawin.im not sure with the model of your car though...

May computer box na ba ang corolla 97? Curious lang i really dont know.
Baka kasi check engine light niya is not a MIL warning.

[umzzzzz]

AFAIK (Correct me if I'm wrong)... all cars which have "check engine" indicators are equipped with computer boxes... Also... may mga codes ang light kapag nag flash... a flashing check engine light indicates something other than that of a steady illuminated check engine light. Better consult a manual or an experienced mechanic.
