New Emissions Inspection Process
I'm sure most of you are aware that as of April 1st there will be new emission standards in many counties that never had them before.
Putnam county is one of them. All vehicles built from 1996 and up will have to pass emission tests.
The problem here is that many of us modded our cars before these new rules went into effect and may not pass. The new test will not hook a sensor to the tailpipe but hook into the crs computer.
As I said most of you are already aware of this.
Has anyone heard of a way around this?
Whoever comes up with it will make a small fortune.
If you've heard anything please don't post it but rather e-mail it, so other not so friendy inquiring minds won't know.
Thanks
Joe

Well as pointed out in the first post the new test has nothing to do with being able to pass a tailpipe test. They will connect an OBDII scanner to the car and check for codes and readiness test status. If you have no codes stored, the CEL is off, and the readiness tests are complete you will pass. If any of these conditions are not met, you will fail.
Some of the electrical "fixes" for the P0420 CEL will prevent the readiness tests from completing so the mechanical fix is preferable.
You can't "cheat" the test by resetting the ECU (either with a scanner or by disconnecting the battery) just before going in, as this will also reset the readiness tests to a "not ready" state and cause you to fail.

I am hoping that the Perrin o2 simulator will fool the ecu. I have a OBD II scanner so will know if it does. If not, I will put the clear the CELs and put the downpipe in a few days before the test and it will pass. The ecu will pass after the reset and downpipe installed.

Clearing codes with a scanner will reset the readiness tests, that is how the OBDII standard works. It doesn't matter if you do a full reset by pulling the battery or with a scanner, the readiness tests will be reset to a "not ready" state. You then have to drive around long enough for the tests to complete, if you go right to the test you will fail. A few days may or may not be enough depending on how much you drive and whether the ECU sees the proper conditions to complete the tests. At least if you have a scanner you can check the test status to avoid going for inspection before they complete.
The Perrin fix may have the same issue as other electrical fixes, they alter the rear 02 signal so the P0420 code does not set, but at the same time prevent the readiness tests from completing.
