It depends. Invest in a cheap OBDII scanner and it will tell you when the monitors are ready. Or drive it 100 miles or so and try again. In NJ you can pass with 2 monitors not ready (except for O2 and catalyst I think), but I'd suspect that Kalifornia wants them all to be ready. EVAP is usually toughest to show ready - takes a long time as it's a combination of cold starts, highway driving, stop and go driving, etc. I never drive on the highway and my EVAP monitor on my truck didn't show as ready even after about 75 miles of around-town driving last year. I passed inspection because the other 6 monitors were ready.
Diesels aren't required to be inspected in NJ according to the inspection station.
