if you guys need codes, I "may" be able to look them up. I have alldata here at home now because I go to school. Also, I have an OBDII scanner. I know it's not the 0 you are seraching, but I may be able to look it up at Alldata???

I can try. Just shoot me a PM or something...

:wink:

[chry*bmb]

sup guys i work at EGV Emissions testing station...

just some general information for those who don't know...

-OBD2 for 96 and newer vehicles get tested for OBD2 test only.

-Diesel vehicles that receive yellow form in mail need to come to Full Service testing station (Schaumburg Location) to prove you have a diesel vehicle. Diesel vehicles are exempt from testing.

-95 and older vehicles need not be tested anymore.

-Vehicles such as pickup trucks, etc... that are 8,600lbs or more get Gas cap test and Bar97 test (aka tail pipe probe) even if your heavy duty vehicle has an OBD2 connector.

Last time i went to the Naperville testing station i swear i saw them put a sniffer probe in a Ford Focus.... Which worries me because with headers and a high flow cat i sometimes wonder if i would pass that test.

I need my Denali tested by the end of the month. I also need my sticker and we all know you can't get a sticker without passing the emission tests.

My problem is that my engine light is on.

Codes:
p0446 (evap vent system performance)
p0452 (fuel tank pressure sensor circuit, low voltage)
p0453 (fuel tank pressure sensor circuit, high voltage)


Anybody know what to do specifically? It'd be greatly appreciated. I'm planning on working on the truck tomorrow after work.
