all about optra parts, troubleshooting, overhauling etc.

hello guys,

medyo naging busy last few weeks sa shop.

fell free to ask again about sa OPTRA nyo..

last scenario we encounter is THE OXYGEN SENSOR...
common na ng trouble siya after na timing belt problem, fuel pump,crankshaft sensor, and coolant sensor.
pero reading sa OBD2 ay OXYGEN SENSOR LOW CIRCUIT P0131.

EVEN palitan ng oxygen sensor same pa rin after days na gamit babalik, mostly bigalang mawawalan ng hahatak then lalabas ang check engine, tataas yung minor/idle then balik sa normal pero naka ilaw parin yung check engine nya,

note; pinaka mahal na sensor is OXYGEN SENSOR about 5,700 estimated value nya... and yes we have SURPLUS NA oxygen sensor.

how did we do it///
its always took time para mawala talaga cya, and indeed may parts na papalitan...
how much it cost///
depende sa history ng oto, and if kung ano na ang napalitan and ano na nagawa...
sure ba na magagawa///
YES... PAGWALANG TINO WALANG BAYARAN, WE NEVER GUEST, WE ALWAYS MAKE SURE NA YUN ANG PROBLEMA, AND PAPATUNAYAN NAMIN SA INYO NA SIRA TALAGA.


COMMON SCENARIO/ PROBLEM OPTRA IDLE/// SPARK S-TECH 2 // AVEO HATCH S-TECH 2 ENGINE;
after may nagawa/ginawa, like spark plug/linis throttle body/ ignition coil/ then pag start mataas ang ilde or namamatay ng kusa.
RPM pag start about 1700 to 2700 rpm.. then drop ng 1200/1,700 rpm .. pag ng gas taas ulit sa 1700 to 2700rpm
pero PAG AUTOMATIC TRANSMISSION PAG NILAGAY SA DRIVE OR REVERSE MAGIGING NORMAL ANG IDLE PERO PAG NABALIK SA PARK OR NEUTRAL, TAAS ULIT ANG RPM.

LOWER RADIATOR HOSE LAGING NAHUHUGOT OR NAHUGOT LANG.
WE have stocks ng mga hose before upper radiator hose,lower hose, bypass tube, bypass heater hose, water pump connecting to bypass tube hose. lahat galing casa, PERO laging nahuhugot ang hose ng lower radiator common yung nakalagay sa bypass tube. pero ORIG hose cya na galing casa, then after many encounter nalaman din namin ang cuase nya.


post ko ilang naencounter nanamin next time, feel free to post your question or txt or call me

Hi sir ask ko lang po kano abutin pag nadurog nga ung socket kasi umiilaw ngayon ung abs light ko after nga mag palit ng transmission support. And any tips po para gumanda ang Fuel Consumption? Asa 7km per liter lang po ako e sa city driving. Thanks po!

Hi sir ask ko lang po kano abutin pag nadurog nga ung socket kasi umiilaw ngayon ung abs light ko after nga mag palit ng transmission support. And any tips po para gumanda ang Fuel Consumption? Asa 7km per liter lang po ako e sa city driving. Thanks po!

yung socket ng abs yung yellowish na, pwede lang naman din cya i dugtong ulit. noo need to change yung socket since na housing lang naman nya ng male and female plug...
sa consumption naman. i advise na follow yung PMS in certainn kilometer reading, need lang naman talaga cya maintain ng maayos, like radiator cleaning, oil change, throttle body cleaning, map sensor hose/egr//purge solenoid hose check/ etc. pag automati transmission hitting 80k atf is a must, we use motocraft atf. it can stand the right temp, need for accurate shift timing.

good day sir, yes po naecncounter nanamin same trouble before, worst pa eh walang check engine so wala kang pwedeng ihatol na palitan at hirap explain bakit kailangan palitan,
pag start normal, idle normal, even aircon or drive anjd reverse position sa automatic transmission ay no problem, pero bigla lang cya namamatay, kahit natakbo or naka park lang.
question muna para ma evaluate;
1. hard starting ba pag malamig, like di cya kaya ng isang start lang, second start or more bago sya dumeretso na start/
2. pag mamamatay na cya eh nararamdaman mo ba na paunti-unti baba ng idle/
3. pag nag shut down ba sya eh may lalabas na check engine pero pag start eh ok na cya ulit, or mababa nja ang idle di kaya pag naka aircon..
4. ano po huling pinagawa nyo before cya magtampo hehehe.
5. may pina convert, dagdag, pinabago sa kanya, like compressor conversion, aux fan na direct ikot agad pag on ang susi, HID,alARM, etc.
post mo sir para mabasa din ng iba na same problem.
sa 1 out of 30 unit na pumapasok sa amin same problem.
