So I have a 2009 Jeep Wrangler X with over 174,000 miles, and I took it in for inspection. The tech came out and said that I did not pass because both the catalyst and O2 sensor were not completed/ready. I can only have one not completed/ ready. He suggested that I drive 45-60 miles. Well, I drove 200 miles and took it in, and still the same results. Has anyone dealt with this before? I have tried resetting the ECU by disconnecting the battery, and I am putting miles on it to see if this will resolve the situation, but I was curious if there is more to this problem.
