Get a suitable OBD2 code reader/scan tool that lets you check CEL status and readiness monitor statuses. Check these before you take the car in for an inspection. But if the CEL is on or there are too many readiness monitors still incomplete or even just one but a critical one you need to deal with the CEL and incomplete readiness monitors.
Also, even if the CEL is dark and the readiness monitors are all set to complete there is the chance the car may *not* pass a visual inspection.
