how much is the new myvi o2 sensor? which part of the probe that have to modify? sensor head or the sensor tapak? too big? too small? tapak size too wide or too narrow? pls share more info as i guess a lot of us have aged o2 sensor.

New Myvi sensor costs RM180 only in Sabah. Okay... To explain the modification, it's like this.
Generally there are 2 shapes of sensors. The stick type where u just plug and play and the another more complicated type (stick with bracket). The Myvi is using the first type where u can just screw the sensor into the hole while my AE111 uses the second type where under the probe, there is a bracket (metal plate with 2 holes for screw attachments). So to let the Myvi sensor fit, all you have to do is just insert a metal plate and the bottom of the probe and then make 2 hole on each side of the metal plate (left and right) to screw it to the exhaust pipe. It's hard to picture... I'll try upload pictures when i'm free. I found one problem in doing this that is the surface area of the O2 sensor being reduces due to the space being taken up by the attached bracket. But it is just minor and the technician said that it is okay...
This is one weakness of the 2nd generation 4AFE engine. The sensors are different and difficult to source. Going for original UMW is insane. Most of the universal O2 sensor sold in the market today are the stick type (just plug and play). Besides that, I found out that this 2nd generation 4AFE is not as smooth and refined at high revs due to the master and slave cam system instead of belt system camshaft. You can hear the gear whine sound when you rev high above 4k rpm...
Anyways, I am still testing my FC after this fix. But based one the needle, it seems like there is no change. But I'll wait until the full tank is gone to get the accurate FC. Besides that, my idle is still unstable. If it goes one like that, I am suspecting that the wiring that goes from the O2 sensor to ECU has a problem and not the O2 sensor...
Headache and being poor because of this shitty FC...
LOL.. U did not test the O2 sensor is working or not after install..? giving the right signal..?:hmmmm:
I wanted to test... but the technician said no need. Sure ok =.=. So did not test... Haiz... Looks like the FC still same... If like that, I don't know what else is the problem now. The wiring from sensor to ECU shouldn't have a problem because the other day, the signal is inconsistent. If wiring problem, there should be no signal at all...
Damn ~
Ermm...:hmmmm: Did u reset the ecu..? maybe u hav 2 try test ur ecu bro.. as i know some ppl got issue with the ecu also.
How to remove EFI fuse ? The fuse located at where ? At the engine bay or near the driver seat ?

Oh ya btw, to reset the ECU just remove the negative connector from the battery for a few hours .. probably overnight .. then its done
I have checked already today... The Myvi O2 sensor can be used...Got reading and it is standard reading. 0.2-0.8 V.
But does this emans the FC is like that???!!!?? WTF???
My FC on my 3sfe has been bad all these years. Full tank 38L~40L can go around 350km only .. suspect o2 sensor problem ..
