General Smog Check

How many OBDII monitors have to be on ready status?

Does California allow any number of codes to be in a "Not ready" or "Not Complete" state? For instance, can you pass smog if the majority of codes are ready, except for one? Is there any margine of leniency or do ALL codes have to be ready?

I appreciate your time.


California smog check regulations allow for one (1) incomplete or not ready monitor. All the reset of the emission monitors must be "complete' or "ready". Furthermore, the Catalyst Monitor is the one monitor that must be complete if the vehicle previously had any emissions defects causing that monitor not to be ready; and the vehicle is (after repairs) being retested.
