Emissions Testing ?

[JimH]

Anything 95 and older, the CEL does not matter. You get the sniffer.

96+ gets plugged in and a CEL will fail you.

I'm pretty sure my cats are shot, I have an 03' with 190k+ on it. I failed in CA but i know they have crazy high requirements. what are the requirements in NJ? some raw numbers would be nice, something to bounce off my old smog tests.

[JimH]

No raw numbers needed. On a 03 if you have a CEL on. You fail. Period. If you have more then one monitor displaying "Not Ready". You fail.

And just to add to this. You can still also fail for exhaust leaks, visual smoke, or leaking any fluid.

[fitftw]

just pull the CEL bulb. Nobody will care unless your car is beyond gutted like mine. I won't even bother getting inspected lol.

Deleting a check engine light will make all your systems "not ready" automatic fail. Inspector will know you deleted them all.

I've made many cars pass emissions that normaly would have failed.

WRX 3" turbo back no cats big turbo. - Pass (If you use open source tuning on your car, you have the ability to turn off o2 senesors, and EGR. It can be set to say system ready -OK

Pontiac Grand Prix Supercharged with cat inefficency code -Pass ( learn how the ECU processes data. On this senerio you buy Vibrant part#11621, install with small jet on the down stream o2 sensors, then clear your codes and drive aprox 100 miles, a good scaner or autoparts store can check your system status. once your status is ready you should be good to pass.

Either way, your ecu must read "system ready -ok" on so you have to fix your problems before going back, there is no short cuts only cheats lol. Erasing it will only make you fail and waist your time.

I wonder if my sensors read not ready or system ok.

They are disabled via uprev.

When it's time to get inspected I'm coming to JimH's. I want him to tell me straight up. Pass or fail and what I can do to fix it

You can find out if you go to a good autoparts store, dosnt matter on the one, but more so the person and their scanner. At my place I can scan and check your status for ready, our scanner dose a mock NJ inspection read. If its disabled it should read ok.

[Godofelru]

Interesting, I'll have to check it out.

I can hook my laptop up to my car to tune and check codes and diagnose stuff, but I've never been able to read if systems had ready monitors.

[JimH]

Can't just pull the bulb as you will fail the bulb check. Plus they still scan it finding whatever it is on for. (96+)

Also those of you that think you can get by by turning the monitors off you can still fail. If the inspector notices everything says N/A then he can fail you for tampering. Meaning you disabled the monitors through flashing. At which point you fail. I had done a reinspection on a member heres SRT4 because they failed him for tampering.

Nope, my CEL is NOT on, no monitors state "not ready". as stated before I believe my cats are just done. they dont "ping" like my Z, and practically everyone elses car does. and I failed my last emissions test. so yeah, I would appreciate some raw numbers(if anyone has either what the state of NJ demands or their own pass/fail data on hand). so if by some chance someone had higher numbers than mine but passed(due to less strict emissions laws), then I wont go spending money I don't have on new $900 cats.

My Previous Emissions Test(South California)

HC(PPM)
MAX allowed:52(15mph) 36(25mph)
measured: 49(15mph) 36(25mph)
average vehicle: 4(15&25mph)

CO(%)
MAX: .49(15mph) .46(25mph)
measured: .07(15mph) .1(25mph)
average vehicle: .01(15&25mph)

NO(PPM)
MAX: 424(15mph) 771(25mph)
measured: 534(15mph) 349(25mph)
average vehicle: 16(15mph) 18(25mph)

When did you go for this emissions test? Your showing me ASM5015 numbers which they haven't done in over a year. You failed for NOx, which they don't measure anymore because a vehicle has to be under a load to create it.

On top of that you do not need a cat to control NOx. That is produced when cylinder temps reach higher then 2500 degrees and then your EGR is opened to lower the temps. So you have an EGR issue. Not a cat. I'm not positive on this "pinging" you speak of but it a pretty unreliable way to test the workings of a cat.

And to answer your question, NJ is a lot less strict then CA apparently. When they were doing sniffer tests on a 03 (which would only be cause of a communication error with your ECM) then 220 HC's are allowed, CO is allowed 1.2%. NOx I couldn't even tell you cause it's been that long since NJ has had to measure it.

I got it tested in feb 2011 in Cali i believe. my engine doesnt have an EGR valve on it(VQ35DE). I know that that sound is an unreliable way of "testing" my cat per-se but i figured maybe the lack of that sound meant something. and since i lack knowledge of the cat, it may have been common knowledge to someone on this forum.

holy crap! I love those numbers . yeah apparently people weren't exaggerating at all when they said CA has extremely strict laws... well thank you very much, the NOx was definitely the one I was worried about, glad to know It's not tested here :D

Do you have to get your car inspected when you bring your car over from another state? I might need to move my car from Maryland to NJ for my job and I'm pretty sure my tires aren't going to pass the tread depth. I know my emissions is fine just not the inspection part if you still have to do that.

[JimH]

If you are registering the car in NJ then yes it needs NJ inspection. If you are maintaining the MD plates then you are subject to MD inspection laws.

Safety is no longer inspected in NJ. Only emissions, visible smoke, and liquid leaks.

And 2/32" on passenger cars was the failing point when NJ did do safety inspections. Which is right bout when the wear indicators are even with the tread.

going for an inspection this weekend. i have no idea how i will do, i have no cat now with the sensor plugged in and tied to the size. The oem stage 1 mopar computer, i have though, doenst look for the 2ndary 02 or something (i really never cared to look into it) but ive herd of people passing. Luckily if someone does look my car is pretty low and the resonator is on the downpipe n resembles a cat.

oh well if i fail ill borrow someone's stock exhaust
