so i had to clear my codes to get an inspection.i had 4 monitors on ,after driving awile i only had 2 monitors left on ,evap and catalyst.i can get it to pass with one on.so my question is how do i get these last two to clear b4 the cel comes back on ?i did drive it till 2 went off but b4 another would clear the cel came back on .any suggestions.the drive cycle doesnt seem to work.i need this darn thing inspected.
gonna have to fix whatever is throwing the code. that catalyst monitor can take up to 6 drive cycles to pass from my experience
what is the code for?
ya, those damn ready/state tests are a pita to figure out, you can follow the steps exactly and they still won't be "ready".
like he said, get the code fixed and then keep driving the vehicle, it'll eventually set.
On hp tuners you set the dtc to report no error for those sensors and all the check will complete.
