I had the cam sensor replaced and was told to do a drive cycle and the codes would clear.I drove 2000 miles and they never cleared.The service light is not on,just not ready codes when they do emissions check

Here are some articles I wrote on Drive Cycles and what to do about them, You can take them to a good shop, as this is a real problem for people. I do Smog Diagnosis and Repair In California, and it can really be tough to solve what I would call 'Hung Monitors'.
