Can someone please list the drive cycle procedures here for an 04 z. STEP BY STEP and in details. I searched but cant find jack. thanx.

 

Are you referring to the emissions drive cycle needed to clear the OBDII not-ready code? I saw one for an older Nissan a while back, it's about 2 pages long with about 50 steps. From what I read, it would be virtually impossible to perform it on city streets because of some of the wacky requirements.


Start here... http://www.autocenter.weber.edu/OBD-CH/
or, do a Google search, you'll have better luck finding it that way.

 

ya thats exactly what im talking about. i even searched google but i still cant find one for a z. WTF.

 

Did you look at one, here's the Ford example:

When you see the requirements about driving certain time lengths at certain speeds, it would be virtually impossible to drive the cycle on public streets (traffic, signals, etc.). You'd have to do it on a closed course or way out on a desert highway.

What is it you're trying to do? Maybe if we knew we could help with a better method.

 

Just drive the car for day or two. Normal driving both city and highway. You will be able to set the monitors quicker that way compared to following the manual. Newer cars monitors set much quicker than older vehicles.

 

ive put 60 miles since i deleted the codes. 2 test have not been completed wich are the 02 sensor and evap. I gotta pass emissions and i need these 2 left completed.

and yes, i have followed those GM steps but they didnt do nothing. and i can do those on public roads. its not like they tell you do do 140mph. idk why the 2 left wont be completed.

btw, i have a Turbonetics turbo kit with a reflash tune and a turbo back with no cats. I also have a aem wideband.

 

I don't know if a day or two of driving will get it to clear or not. I had a CEL come on in my Toyota and stay on for about 10 days before it went back off. With a turboed car and no cats, you may never get it to go off.

 

There has to be a way to trick that 02 sensor. hmmmm....

GREAT MINDS UNITE AT ONCE!!!!!!!!!

 

Thought about this?

damn, i wish that guy was still on so he can make one for me. im kinda still learning about electrical stuff but i guess i have no choice but to make one.

 

lol i have the perfect solution.

go down to autozone and buy non-fowlers
its like a little cap that fits perfectly over the o2 sensor.

then...
goto a mulffer shop and get your car on a lift.
then take out the 02 sensors
it takes some force.... might need some heat (torch it if you must)

yank it out
get the non-fowler and cap the o2 sensor...

put em bak in and
then reset your computer..

 

Committing emission fraud by tricking ecu to show a pass is a serious crime, if and when you get caught.
Worstcase: Many get caught after they resold the vehicle when the new owner fails emissions and investigates then the state comes looking for the fraudster!

AS IS doesn't protect you from emission fraud.

 

k. when you re sell it take them out.

and who cares. i mean there are many car enthusiast who get on there car and wanna go fast.. plus the billions around the world //\\

its doesnt help the world but neither does any gasoline engine
