INTERESTING: Secrets about emish. tests in PA

[LosDiosDeVerde86]

for those of you who have or would like to mod you '96 or newer subie's exhaust system (hallow out cats or muffler) or anything that may effect the emishions, there is an easy way to get around failing the test upon inspection.

 

1. hide the OBD2 connector

2. Make a false OBS2 connector

3. disable the OBD2 connector

 

Why?

 

The new emishions tests in PA (maybe other states as well) get reading of the emishions from the computer via the OBD2. When the computer asks the tech if the OBD2 is accessible or found, the tech either chooses yes or no. if there is no OBD2 found, the test skips the emish completely. Also, with #2 and #3, if the computer cannot connect to the OBD2 the emish is skipped completely and is AUTOMATICALLY passed.

 

Just some helpful hints for subie drivers in PA. Now let's see some mod soobs on the roads od PA!

They don't use the sniffer test up there for cars without OBD2?

[Hondasucks]

cars without OBD-II they prolly use a sniffer, but a car with OBD-II runs its own emission test. Also, if you hollow out or remove teh cat, there is a thing that you can get to plug into the second o2 sensor harness, that fools the computer into thinking the cat is working.

nope, the sniffer is only used on 96 and older. if there's no OBD2 there's no test

the new machine doesn't have a sniffer
