California Smog Readiness Test Failure
I recently took my car (2001 Ford Focus ZTS) to test only station for Smog Check prior to registration. It passed all emission requirements but failed what technician described as a “Readiness Test”. The form specifically states “This vehicle failed the MIL/Check Engine Light Test due to failure to successfully complete all OBD self tests”. I got temp registation but need to deal with issue at hand. My money is tight (like most everybody else) and my questions are:
1. Is this an easy fix or will it require taking to repair shop?
2. What part is required for replacement?
3. Any idea cost/time required to fix it if repair shop is required?
Your feedback would be greatly appreciated. Take care & “All The Best!”
