    hi all...

    just wanna have opinion from you guys about my car. i drive EK3.
    last night orange led "check-engine" suddenly appear at console.
    what does this indicates ?

    i stop a while and do some check. water for radiator still a lot. battery
    still gives it green color (mf). oil level slightly lower than upper indicator.
    i start the engine back.. now the orange light no more appear. worry
    with it, i add on some more engine oil.

    the question is, what does the orange led "check -engines" means ?

    other thing is that what is the symtom shown by car when it needs for
    new timing belt or cluth plate ?

    thanx

    CEL lights up means there's sumthin wrong with the car...can be wiring, sensor, etc....if u dont know how to check it yourself, bring your car to any workshop that can read Honda error code....they will tell u what need to b replaced/repaired...

    i think u need check for the error code first before you can determine what's the cause.
    and if dunno the cause, how to inspect your car further?

    not sensor for the CEL laa...i mean mayb got others sensors got problem so it tells the ECU to tell the people of its problem via the CEL...to know what prob exactly u need to short 2 pins at the ECU, then the CEL gonna blink to tell u what's the error code....then you'll know what exactly is faulty...

    sassuka...

    if u wanna check it yourself (diagnostics), go to google and search for "Honda ECU error codes". There should be a link to hondatech website and will provide you with the DIY method on determining the error codes. All you need in determining the error is a paper clip or a piece of a very very short wire.

    pgmfi website will help you as well...

    It'll be a good experience.......

    1 - Primary oxygen sensor low/high output
    3 - Manifold absolute pressure sensor low/high input
    4 - Crankshaft position sensor
    5 - Manifold absolute pressure circuit range/performance problem
    6 - Engine coolant temperature sensor low/high input

    13 - BARO sensor low/high input or error
    14 - IAC valve system fault
    17 - Vehicle speed sensor circuit
    20 - Electrical load detector circuit low/high input
    22 - VTEC system malfunction
    23 - Knock sensor circuit fault
    30 - TMA/TMB signal line open or short
    41 - Primary oxygen sensor heater circuit fault
    45 - System too lean/rich
    48 - Primary heated oxygen sensor malfunction
    61 - Primary oxygen sensor circuit slow response / range prob
    63 - Secondary heated O2 sensor low/high output
    65 - Secondary heated O2 sensor circuit fault
    67 - Catalyst system efficiency below threshold
    70 - Automatic transaxle
    71 - Cylinder 1 misfire
    72 - Cylinder 2 misfire
    73 - Cylinder 3 misfire
    74 - Cylinder 4 misfire
    80 - EGR insufficient flow detected
    86 - Engine coolant temperature sensor circuit range/perf prob
    90 - EVAP system leak detected in fuel tank or canister area
    91 - EVAP fuel tank pressure sensor low/high input
    92 - EVAP system insufficient purge flow

    Now...if only I could explain correctly where you should insert the wires...difficult to explain without photos. It's usually located beneath the carpet near the left side of your dashboard. If it's still a virgin, there should be a green rubber like cover covering the connector. Remove the covering and insert both ends of any short wire to each ends in the connector. After that's done, start (not ignition) your car. If your car has some errors on them, read the blinks appearing on the checklight.

    To get the number of the stored error code you need to count the number of long flashes and the number of short flashes. The long flashes will occur before the short ones. A long flash represents 10, and a short flash indicates 1. So if the flashes look like _ _ - - (where _ is a long flash and - is a short one) then the error code is 22.

    If there are multiple error codes, then there will be a noticeable pause before the next code starts.

    thanx to crower75 fo sharing the info...

    i dunno that CEL got so many sensor to detect car fault !
    looks like a dumb for not knowing much about own car tech.. ha hahah
    will do search on web and photo to conduct DIY on honda ecu error codes.
