Default perrin O2 simulator and inspection

I was wondering if anyone in NJ put their car through inspection with the perrin O2 simulator.. did you pass??

i got a turboback now and i'm thinking about getting one in hopes of passing inspection. any help would be greatly appreciated

oh and btw, what really sucks on my part is i was given a one year sticker instead of a four year.. can i change that?????

To answer your first question, I believe the perrin 02 simulator is an electrical fix for the CEL which means that you will not see the CEL but that the sensor will be reading as not ready which means that you will fail OBD II testing.

Do a search for mechanical cel, this uses some spark plug adapters to move the sensor away from the exhaust flow so that it will read a temp difference and not throw the CEL.

Next question, if you bought the car new I would go back to the dealer and see what they can do for you about getting you the correct inspection schedule.

Good luck.

well i know that when i go to the inspection station, they plug into the OBD. wouldn't that mean that they check emissions electrically? i dont all too much so i wouldn't want to go on any further...

The OBDII testing involves the inspector plugging a scanner into the diagnostic port to check for stored codes and OBD "readiness test" status. If the CEL is on, there are any codes stored, or the readiness tests are not complete the car will fail.
As Panic said the electrical (wired-in) CEL fixes are known to interfere with the readiness tests even though they do eliminate the CEL, so if you are in a state that does OBDII testing such as NJ or NY you should NOT install one of these fixes. Do the mechanical fix instead.

youre allowed to fail just one obd test. itll most likely be your evap so get your o2 all corrected.

The search button is your friend

Do this Mechanical fix:

1.Go to Pep Boys, AutoZone, etc and purchase 18mm spark plug anti-foulers.
2. Drill through the end of one the fouler with a 1/2" bit, so that the 02 sensor can clear the hole.
3.Screw back on the other side of the anti-fouler, and screw back in the entire unit into the 02 sensor slot on the bottom of the DP.

If need be combine multiple foulers to get desired effect.

I would contact the DMV and/or dealer and get your 4 year exemption. Why are you even messing around w/inspection issues with a nearly new car that should qualify for 4 year exemption?

just passed inspection in NY state with this...

http://www.wrxevolution.com/exhaust.asp


that o2 simulator there

turned off my check engine light, hasn't come back on yet.
and it didn't throw any codes or read not ready on inspection
First time my check engine light has been off in like a year.
I imagine the perrin one would do the exact same thing.

this site helped...
