I have a 2001 F-150 5.4 SC that won't pass emission testing because the EVAP and Catalyst systems are not ready. Obviously the testing facility told me to drive it more, but I have probaly drove 500 miles since then and it still is not ready. When I scan the vehicle with my AutoXRAY EZ-Scan 6000 I get the following information under the test results of the systems.

OBDMID $11 Fail
Test ID $01
0000 NOT>=0200
0000 <=FFFF
HO2S11 - Voltage Amplitude - Bank 1 - Sensor 1

I was guessing this was a faulty O2 sensor, but I have since replaced the sensor, cleared PCM and it still scans the same code.

Can anyone maybe explain this description in more detail to me to help me understand what I am missing.

Thanks - Jeff

 

Google Ford drive cycle. I'll see if I can find my papers.. but upon start up you have 30mins that the computer will register all different parameters that are used when passing emissions.. It took me 1300 miles to get my truck do the drive cycle nd register all the info I needed.. I was down to 2 different ones that wouldn't pass and I finally reset my battery which resets the drive cycle and went out for an hour of normal driving and it passed.
