maf sensor?

[hotwifey37]

ano ba yun? sabi ng mamang mekaniko...papalitan daw sa car ko kase sira na...kalerky....di ko naman alam itsura nun....h

[uls]

nag me-measure ng airflow na pumapasok sa makina

sends signal to the ECU

pag sira yan di maka idle nang maayos ang makina

Mass Air Flow (MAF) Sensor

Symptoms of Wear or Failure:

Engine may run roughly or not at all
Poor performance
Excessive fuel consumption
Stalling
Check Engine Light may come on or blink

Mass Airflow Sensor

appearance varies for different brands. normally, the MAF sensor is located after the Air Cleaner and before the Throttle Body.

usually, walang continuity dahil sa alikabok lang. try mo muna i spray ng electronic contact cleaner. pag ayaw pa rin, check the 2 wires inside the sensor, baka napatid lang ang wire, pwede hinang dyan. hope this helps

[hotwifey37]

thanks mga pogi

Are you serious?

[oj88]

Are you serious?

Was thinking the same thing...

That's one precision measuring instrument right there. A slight change in ECU reading because of fixing it the wrong way could mean engine hesitation or poor fuel economy.

Besides, these parts are consumable items... like O2 sensors or your spark plugs. They are meant to be replaced once they've reached the end of their operational life.

pede pala ihinang, bagong kaalaman ba yan?

[[archie]]

Ummm... Bakit hindi pwede solder kung napatid lang wiring?

[shelu]

yes, sirs. pwede ihinang and we have done it before. may wires sa loob ng sensor na pwede ihinang pag napatid lang ang wires. it is bit tricky but very doable. why buy a replacement if you can repair it. tricky dahil pag nahawakan mo yong wires, grounded na. actually, i learned this when the maf sensor of my 98 sentra malfunctioned. nabasa ko sa forum ng sentra club na pwede palang ayusin. nagawa naman at ok na.

[vvti2.0]

Ang bawal hinangin ay yung umiinit na element, parang filament yan sa loob.. Pero kung yung wire lang naman na pang conduct ng signal, pwede yan hinangin..

[joemelr]

Sirs linawin ko lang po, di ba yun wire na manipis sa loob filament like yun "fragile" madali maputol lalo di maingat sa paglilinis nito, Itong wire ba sinasabi nyong pwede i-solder? o yun bigger wires na connected dito?

the sensor contains a thin platinum wire, which can break if handled incorrectly

if yung "hot wire" sa loob ang hihinangin, maging accurate pa rin ba ang data ng sensor? wala bang effect yung solder sa platinum wire?

[shelu]

ang pagkasabi sa akin, pwede hinangin kahit saan sa dalawa. yong sa maf sensor ng sentra ko, doon sa gilid ang napatid, sa side wall. medyo tricky paghinang dahil pino ang wires at di pwede hawakan. natutunan ko to sa club nisssan sentra. about accuracy, i think its alright as long as it is done correctly. sa akin kasi, lakasan lang ng loob, anyway, papalitan ko na rin lang din, subukan ko munang ayusin. palagay ko, naging ok naman dahil balik sa normal ang gas consumption ng sasakyan.

[MrQ5]

di ko talaga ma gets, yun ba talagang sensor sa loob yung hininang mo?

di nahigop ng engine yung naputol na wire?

malalaman mo naman sir yung accuracy, may tolerance sya na resistance value, need mo ng multi tester/ohmmeter.

[lowslowbenz]

Jeez, if the MAF sensor is dead, no point in "repairing" it, or soldering it.

Thats just a cheap wear and tear part. I would GLADLY spend good money on the insurance of a new OEM sparepart, than having to be stranded on some lonely highway, at night, with my loved ones inside the car, all because my soldered or repaired MAF sensor fcuked up.

[red_one]

magkano ba ang MAF sensor?

[shelu]

magkano ba ang MAF sensor?

almost 2k petot din po yong sensor, nong sentra 98. yup, i agree. there is no better way than replacing the defective part with a new one. i was just sharing how we did it. tayo po kasing mga pinoy, mahilig sa kalikot at butingting sa sasakyan. lalo pag luma na ang sasakyan, kung bago at sagot pa ng insurance, syempre, palit agad ng bago.

hindi po nahigop ng makina yong wire kasi isang side lang po ang napatid. kung natanggal ng tuluyan yong wire, talagang palit na ng bago. tama po kayo sir, malalaman kung accurate pa ang sensor sa pamamagitan ng multi tester.

[red_one]

if back to normal gas consumption ang sasakyan mo, then i think okay ang pagkahinang mo. good thing siguro na sa side ang putol at hindi sa gitna ng hot wire.

if faulty ang MAF sensor, ito possible na mangyari:

- Check Engine Light will illuminate
- Engine runs poorly
- Vehicle may stall and/or hesitate on acceleration
- Poor fuel mileage
