    2007 5.3 silverado DOD disable and emissions inspections

    Hi Everyone,

    I did the DOD disable mechanically and with HP tuners due to a collapse lifter. Engine is back together and working fine with no engine light. However to pass inspection I need my catalyst and evaporative system sensors to say complete. As of now they are incomplete and the ask here is would the DOD disable with HP tuners turn those sensors off? I am hoping no. The inspection station says I just need to drive 10 to 15 minutes at highway speeds for them to come on or do a drive cycle over night as well. As of this morning I had 3 off and with 75 miles of driving between 30 to 50mph I was able to turn the 02 sensor on. Anyone's input would be great.

    After 260 miles its still showing incomplete for cat and evap. my question is Does DOD disable do something where it would turn off this function?
