HELP!!

I didn't pass inspection, not because of error codes but because it spit out "not ready" on my c02 sensors.
Do I just need to reset it??
Or do they need replacement??

Can't really give you any good help until we know the pedigree of your truck. Since you mention 02 sensors, it's a gasser, but is it a 5.4 or a 6.8? What year?

Read this, if your truck is a V10.

If you recently cleared the codes or had hte battery disconnected for any extended period of time, you will need to fully cycle hte computer. Typically 100-200 mile trip will do it. Not ready doesn't necessarily indicate a fault, it just means it hasn't completed the cycle yet for most vehicles.
