Cleared check engine light. How do I pass smog check?

Clearing the Check Engine light does not repair anything - it only turns off the light and clears the error codes. The problem(s) that caused the light to occur are still going to be present and the light will probably come back on, anytime from a few minutes to a few days depending on the problem(s). What you NEED to do is to extract the error codes that come with the light and take the corrective action(s) to repair the deficiencies. That will probably make the vehicle able to pass smog checks. Of course, now that you've cleared the Check Engine light, you've also erased the error codes, so you will need to wait for it to return to get the data you need for repairs.
