Default OBD 2 Readiness Monitors.

Do all the monitors have to be set as ready to pass emissions inspection. I live in NY and I know they use the federal guidelines.

Depends on year and state, my 99 was able to pass with 2 not ready conditions. Here's info on my adventure. It's pretty old but I believe it's still valid information.

NJ has pretty similar laws as far as inspections go. I failed readiness with 2 sensors. I believe in NJ anything reading "not ready" will fail. To let you know, I have a vararam which occasionally throws a maf/lean code. I reset it usually as I comes up. What I didn't think about, was deleting the OBD code also resets the sensors. 2 days later, I went for inspection, not realizing and failed. Drove around for a few days and went back and passed.

In NJ the two rear sensors can be tuned out and you will still pass the state inspection with no problem. Call Doug at East Coast Supercharging in Cream Ridge, NJ for more info. The same probably will work on NY cars. Besides when he does your car will run better.

BTW, interesting thing this week. I was getting codes on my S-10 pickup. It turned out I had a faulty O2 sensor. It just so happened the faulty sensor is the same as the two no longer needed in my Vette exhaust. Cheap fix, works perfectly. Glad the General was thinking ahead.

I did some reading and most states follow the Federal EPA standards. Any car 1996 to 2000 can have 2 monitors not ready and 2000 and above 1 monitor. So if you have a check engine light and and reset it and can get it there before it goes on and you only have 2 monitors not ready you are O.K..

Depending on the year model vehicle, OBD II vehicles can miss either 1 or 2 and still pass in Texas. At least in the most restrictive counties in the state.

Do NOT do this. Every time you clear codes you reset all your monitors to a Not Ready state. Most will go back to a Ready state only after you complete a certain number of drive cycles. This was done for reason so you cannot just clear codes and go to the inspection station and expect to pass. Pull the codes and find out which system is causing the check engine light and address the issue. You can have 1 system Not Ready as long as the check engine light is not lite and still pass. You do not say if your car is modified or not. If so, there are ways to tune around the issue in some circumstances, but if your car is stock, get the issue causing the MIL fixed. Good luck with it.

Who said anything about reseting codes. I was just discussing how you can pass with a couple of monitors not being ready even though you may have a problem and the chech engine light is not on.

I have a friend with a Ford Taurus and the car needs cats. He dosen't want to put in $700 for cats so he resets the computor and goes through the drive cycle until all the monitors are set except the cat one. He goes in and it passes.

I have a speed density tune and a MAF code since my MAF is of course not functioning. Since this is my only code and everything else was OK, my tuner turned off the check engine light and I was good to go on my inspection. This is an example of what you speak.
