hey guys i'm in desperate need of a O2 simmulator as my check engine light keeps comning on after i installed my exhuast. Anyone know where i can get it and how hard is it to install it?
thx

 

what is 02 simmulator for?

 

i think he meant o2 sensor.

 

I think O2 Simmulator uses to match the b4 and after cat O2 sensors' readings for OBD2 ECU. It fakes the ECU for any fault reading after the cat. People use them if they remove the cat.

but if in this case only the exhaust is changed, it's not needed. It shouldn't cause any fault code either, b/c exhaust is behind the sensors...

 

hey guys thx for the replies.
i'm not exactly sure why my check engine light is on. I just know that i remove the cat and the store that help me install it said i'll need a o2 simmulator (could be sensor, maybe i heard wrong) or else my engine light will stay on. If i unplug the battery, the car is good for about 20km, then the engine light is back on.
Anyone have any suggestions what to do or how i can get the problem resolved?
I'm totally lost, and its quite annoying that the engine light is on bcuz i heard when the light is on, the engine is in limp mode???

 

ok...u removed the cat...now I understand.

The only place I can think is here .

good luck, just 4 days left

 

hey buddy,
you are in big trouble.....because you can't get rid of that and you won't be able to pass air care..

 

his car is 03, so he won't need to do air care until 2005.

just install the cat back for 1 day for air care then remove it again. shouldn't cause u more than $100.

 

yup thats what i plan to do when its time for aircare.
thx for all ur help.
now i just need to find that part.
Anyone know where i can get it locally? Don't really feel like getting it online as i've never purchased anything through the internet

 

did u ask AJ?
