Just went through this. Find someone with a STAR/DAS laptop or use an Actron scanner to pull the codes and clear them. Either fix the issue or clear the codes and hope your ODB2 I/M checks complete before the check engine light comes back on. In California, they allow zero incomplete sensor readiness checks. Not fun, good luck.
