Does anybody have a method or anybody can point me in the right direction.

The CEL can be on if the ECU exhausted its attempts to try to get a readiness monitor test to complete.
If you clear the CEL you also reset all the readiness monitors to incomplete. A suitable drive cycle is thus required to give the ECU time to complete all the readiness monitor tests.
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.
