is it necessary to install an o2 sensor especially if there isnt an emissions law where im at? i mean does the engine really work any better or worse without it? and my car has hondata, do i have to change the ecu for a d16z6. (previous owner had the car turbo'd with a non vtec 1.6 head)

yes... the o2 i believe signals air/fuel ratio. as in how much more air or fuel should be added to the mixture.

 

anyone know where i can get a write up of how to change it to a four wire o2

 

unless you want your car to run really rich and get terrible gas milage, i recommend running with a 02 sensor. And your hondata program would be Completely different for a D16z6 as apposed to a non-vtec turbo D. my guess is you prolly shouldn't try to figure out any type of wiring on your own.

its the same 4 wire or single wire just run a o2

 

anyone have a pic of the O2 sensor plug, i think i might have switched the pins when i was removing it. I have code 41 too, O2 sensor heater code, thanks guys.

i was running without the primary o2 sensor for a week and my car ran fine. right now m y secondary o2 sensor is bad and i still have the same gas mileage. according to my car the o2 sensors dont do ****

 

what if i dont have a O2 sensor and the ECu is not complaining?? shoudl i still get one too?
