Toyota Vitz choked cat removal and noise solution after cat removal

[SER_GTR]

Car Is Question will Be Using 4 Wire Heated O2 Sensor......Flange Type (I Guess) But There Also Comes Thread Type.......Even Universal O2 Sensors Works Fine ....Just make Sure The Fitting Matches ...There Are Aftermarket Universal NGK/Denso's O2's Available On Ebay/Amazon.....If You Have Anyone Coming From Abroad...

Ask Them To Fetch And Bring It For You.....You Will Save Quiet Much Of Money.....!

[SER_GTR]

that is why my business was usually called - "loot ta hai bhai" - meray qareeb ka mechanic kehta hai engine badli karo - yeh kompanee faalt hai, woh zulfiqar pagal kehta hai ke yeh 2 sensor kharaab hain or iss se engine set hojayega - paagal aadmi naya sensor ki baat karta hai - sherhsha se nahin leta - japan se mungwaata hai.

bhai rozi roti chalein ya saari tankhwa gaadi pe lagaen. - these type of people are morons, they want a shiny car but do not want to care for it - more like, biwi chahiye super model magar uss ka nakhra nahin.

oddly my prices were exactly 10% more than wholesale price of the items - plus i had fixed pricings for labor.

Yeah, it has 4-wires. This is the post-cat O2 sensor I think:

Just wanted to know if there's no issue in using a universal O2 Sensor (be it NGK/Denso), crimping won't really be an issue for me.

[Xulfiqar]

the post cat in all car is an O2 sensor, the pre cat can be an AFR sensor or an O2 sensor depending on the car. If you are going to purchase universal items for a japanese car or any system that originally used japanese items. Then only use Denso/NTK items. Using Bosch, Honeywell etc can result in error.

I think the pre cat on mine is an AFR: ToyoDIY.com

How does one check (or tune?) if the AFR is working correctly or not. For O2 I know it should be switching between 0.1V - 0.9V (rapidly) @ normal operating temperature.

[SER_GTR]

The AFR Sensor Working Range Is 0-3.3V Mostly

Below 3.3v = RICH

Above 3.3V = LEAN

It May Vary So Better Check With Engine Manual 1st....!

Its Operating Temp Are Above 650 Degrees Celsius So Its Heater Is Also Precisely Controlled By ECM

as ser said

@xulfiqar @ser_gtr Thanks for the replies, appreciate it. I have tried a lot but can't get a hold of the service manual for Axio but I do have its user manual, though it mostly has the general info i.e. oil specs, quantity etc.

AOA,

I simply dont agree with whats being said here, I bought 2003 Vitz back in 2006. Odo at that time was 46,000kms.
Since then its being used in Pakistan, on super petrol that is available locally (adulterated as PW's say).
Car is maintained by Toyota Garden, the odo is 116,000kms we never had the cat choked.

Dont spoil you car buy taking out Cat Convertor, take it to 3S dealership for tuneup and happy motoring.

Are you sure there's a cat present in your car?

There are high chances the previous owner might've removed it.

i has that same point of view as urs...
my father told me to buy a new CAT instead of removing it i dnt want my car to be toxic for others, but i said that it will also get chocked after few kms,, so FAIDAAA???..

bhaijaan aap ne toh wohi baat kardi ke nahane ka kya faida kal dobara badboo aiegi muje se! brush karne ka kya faida subah dobara daanth gande o jaenge! so kya faida nahanay ka and brush karne ka!
