It's not a visual check but they do plug in, power down the ECM and verify no codes, that data is then uploaded to State of PA.
Only 6 counties have emissions, 3 around pittsburgh, Beaver, Allegheny and Maybe Washington and 3 around Philly.
From what I can tell the issue comes when you use the device/software that tells the ecm the rear o2 sensors are working.
somehow this is a high flow detected and that trips the CEL.
As long as the ecm is getting reasonable values from the o2 sensors it should trip a cel. I don't think they will look at o2 sensor position and such during and fail it for that. Hell aftermarket converters used as replacements may not put the sensor in the factory location.
So you could get an address that is not in these counties and register the car there, or you could drive less than 5K a year and get it exempted. Some things to consider!
I live in Dauphin County and we have emissions. They failed my C6 because one of my cats was going bad so I know they hook it up to the OBD II.
Are Kooks "green cats" the same as their high flow cats or are they different? Do you still have the part number?[/QUOTE]
The part # for the standard high flow cat is 6028-cx-2011, the part # for the green cat is
" Product ID: 6028-CX-2011-GREEN
2011-2014 Ford Mustang Shelby GT500 3" Stainless Steel GREEN Catted X Pipe 5.4/5.8L "
.............................These are $ 400.00 more than their standard cat, pretty sure they are not the same.
If these "green" cats are for the Shelby 5.4/5.8L engines will they still fit the GT with the 5.0?
