Checking your O2 sensor

[muzhaffar]

how about 02 reading at apexi pen type?
is it give voltage reading from 02 sensor?
previously, my reading flactuate a lot..
now, when engine is cold, it flactuate until reach value 4.99 and stop there..doesn't increase further..
is it the sign of o2 failure?
where is the correct place to find a new o2 sensor?for 3s-gte

anyone can recommend best place to look for new o2 sensor with reasonable price?

New O2 will cost you more than RM500 haha.
I bought a used O2 at RM80. Working fine.
Anyway, if budget isn't an issue, new is always better than used in the long run :)

You may monitor the O2's feedback signal with Apexi Turbo Timer.
However you cannot judge O2's condition with the timer.

Good info here levin818. I tried this out and when I reached the step "Keep your RPM at 2500" my meter reading remained at 0.92-0.93V area. Same thing when I'm idling.

I have to point out that I'm using a digital meter. Is it because of digital meter got lag or my sensor already kaput?

However, when I revved quickly to 3000 and back to idle, the reading did move from low volt and back to steady 0.9xV. And when I plugged out one of the injector cable, the reading oscillate between 0.2-0.9xV consistently.

dont have the meter T.T anyone have it can rent ~

Most likely your O2 is not in good condition...

If you are using ori Apexi pen meter, yes you can read O2 voltage from the pen meter by switching the reading to A/F mode.
I only count the O2's reading at 2500rpm but have not try out at cold start so connot comments on your status.
Have you found your new O2 btw?

Haha belanja kopi mamak .. teh ais anyone ? Make a TT session for all the toyotarians to gather and have a nice chat haha

 

[et_box]

Eh, agreed! Need to consult sifu again... Can we arrange one at Old Town?

hi... i bought a used car that didnt has o2 sensor, what will happen if car running without it...?

High fuel consumption, poor acceleration, engine not happy to rev..

hi does evo 3 have diagnostic connector? if doesnt have what can i do to check my o2 sensor?need to check it badly :'(

Hello EVO, if not mistaken, EVO3's diagnostic connector is above the driver's foot rest location. However Mitsubishi do not have "TE1" and "E1"... and i have no idea how to initiate Mitsubishi's ECU to check the O2 sensor.
Btw, whats makes you feel that need to check the Os sensor badly?

:stupido2:.. OIC.. No wonder $20 only enough for pusing2 in city.. i dont know where to find O2 sensor here.. any help from east coast??

Thank Levin....

 

[levin818]

naj, your ride is GZE?

you can get a new genuine O2 sensor at RM450 @ Fortune autopart supplies. address is 6, Jalan 20/16A, taman paramount, 46300 PJ. I just bought this sensor from them last saturday :)

yap.. mine is ae92 gze.. plus i also have problem on my TPS.. reading was not right when i connect E to VTA..

 

[Veloc]

Thank you for sharing this Levin 818... Your meter panel... Blacktop ah ?

 

[levin818]

You are welcome Veloc.
My ride was BT engine mated with SVT wiring + ECU. Meter panel is ori from SVT.

TPS usually won't give problem le. How do you measure that the reading is not right?
