Got a New Jazz GD3 VtiS model and got the headers cat exhaust changed to the Xforce set up. but my engine light keeps going on. is there anyway to fix this.
I believe it the 2nd Sensor on the cat.

Toda installed it and they dont know how to fix it.

Please help it getting anoying..

they might have ****ed the o2 sensor.
but you never know, go get a dealer to check for the ecu codes.
if the 02 sensor is ****ed, it's ****ed, have to get a new one.
lol.

no that is quite normal for the 05+ when you changed Header + high flow cat... I bought a o2 sensor from US, thought it may fix the engine light problem but NOT... tho mine comes on and off ... I think if you use Spoon header this problem will not occur...

the headers are identical as the spoon ones,xforce made a copy

Yea but with xforce, the o2 sensor is way in the bottom but if you ahve a look at the 06 vtis, the cable for the o2 sensor is not as long...

I know this engine light doesnt occur with the jazz '04 below...

Is there a way to stick like a diode or something to terminate that sensor

**UBH320** · 25-05-2007 04:25 PM

cut the wiring/cable... ask anjingbalap... he maybe able to come up with a solution...

This method has been pr oven to work on the USDM Fits that get the MIL when using certain brand headers and pipes.

Adrien(toda) say that the stock cat is a 3phase cat. and that the hi flow isnt. and thats the problem. I have no idea what the sensor looks like but i'm hoping that if i unplug it it will stop the ems light and not affect the car.

U sure. Adrien told me to take the sensor out, leave it hanging and plug the hole up. It will then think the cat is doing a super job of cleaning the emissions.

man i dont know crap about this . thanks for helping me with this.

ah... dont worry about ur MIL out.. if u still worried follow the Claymore sugesstion.. on mine i Bypass the wire by using piggyback...

btw on jazz if MIL comes on limp home mode.. vehicle still behaving the same way

.. ussually on car when MIL turn on is either ur O2 sensor stuff or ur Catalyst converter stuff.. .. never on engine

...if engine damage is OIL PRESS Indicator LID on

so there is 4 choice for you
1. buy the longer bung on ebay (Claymore Idea.. and Didnt work on my car)
2. buy piggyback (thats wat i do... but times still on coz my car runnin Rich A/F )
3. pretend that the MIL doesnt turn on (thats wat i do before buy piggyback)
4. Cut the wire that make the MIL light ON (NvM idea)
