HELP: Civic 2000 Malfunction Sensor

[CargoBoy]

Gurus - Need your help. Im encountering intermittent blinking of "Engine Malfunction" indicator dash indicator (instrument panel) of my Civic VTI 2000 (SIR Boy). This is the colored orange indicator on my dash with icon that looks like a conduit pipe. The manual says that this sensor sense the emission level of the engine. The light goes off when i stop the car and it will light up again after i drive for some more kilometers. Can you please help on how can i fix this? Is this a major problem?

bring it to a shop that has an engine scanner; speedlab, speedyfix, etc. anyway that kind of intermittent problem is a sign of a loose/busted knock sensor.

sir, Check engine ba yan, ganyan din nangyari sa ESi ko, pina-diagnose ko sa Casa honda cars pangasinan dito sa remote office nila dito sa may baler qc. pinalitan nila ng speedometer sensor isang set yun. cost nun?P3,8++ kasama na check ng ECU.
try mo muna i-reset yung ECU mo, by doing this, disconnect mo and connect mo yung negative terminals ng battery mo kung ganun parin, may problema talaga.kung hindi, may busted wire/harness diyan sa may engine mo.

pa scan mo na yan asap, pag ang MIL (malfunction indicator lamp or check engine) ay nag biblink that means meron active misfire that need immediate repair otherwise you're going to kill the cat con sooner. blinking is different than steady illumination of the MIL. steady means there was a problem detected by the ECU (or other computers) that needs attention but not as critical as the blinking MIL. and pls dont ever disconnect the negative battery to reset since ma eerase ang fault sa ECU and hindi mo agad maretreive kahit gamitan mo pa ng scanner. if the problem goes away the computer will extinguish the mil automatically after 2 good trips if it doesnt see the problem again. the fault will be erased in the comp memory after several drive cycles (most are within 40 warm-up cycles).

ps. mods paki delete na lang yung above post ko

Kakatapos mo lang ba mag-change timing belt?

Kasi baka yung kagaya nung nangyari sa akin.....after ng timing belt change eh nalimutan i-ayos ng mabuti ng mechaniko yung mga wiring kaya kumikiskis dun sa belt..... Nagdidikitan yung wiring kaya umiilaw yung MIL ko...

Nung inayos ulit eh ok na.....

So baka minor lang yan kaya check mo muna...

should be relatively easy to diagnose naman. swing by and we can check it for you.

Hi EG - Thanks for the input - Yes, not sure kong coincidental nga yun. The 1st time i encountered the intermittent blinking of check engine (malfunction sensor) indicator nagloko na rin yun speedometer ko, now the speedometer is completely dead. Will check shop with scanner capability.

Hi SUV - Timing Belt was changed when Odo reach 80K now its on 114K mark. Wala naman akong ginalaw sa makina lately, basta bigla na lang itong lumabas..
