June 19, 2011I have a 2001 Supercrew 4x4 with a AEM brute force intake and did not pass my emissions test in Houston. I have the cat and evap not ready when I scan but no check engine light on. Anyone had or seen this problem before and have any ideas how I can fix it to pass my emissions? I can have 1 not ready but not 2 to pass the inpsection.

June 19, 2011Do you have the P1000 code?
Have you changed the tune or unhooked the battery lately?
If so ,you`ll need to complete the 0B2 drive cycle.
June 19, 2011I have done both, i returned my truck to stock before getting the emission inspection and then the guy at the inspection place disconnected battery and tried to reset the computer. I have used 4 different scanners and the P1000 code only comes up using my edge evolution.
June 20, 2011You will need to complete the drive cycle!
And sometimes it can take 3 or 400 miles...lol
If you have a P1000 code ,it will not clear until the drive cycle completes and all the monitors are checked and passed.
