1997 Saturn SW with EGR O2 AND CAT monitors not ready.
My Saturn has 3 not ready lights after changing my battery. the o2, CAT and EGR. I managed to get the CAT and o2 reset, but the EGR is still not ready. Will I pass smog if one code isn't ready. Answer:
Yes, your Saturn can pass with one (1) monitor not set... so long as that
monitor is not the CAT, the Oxygen Sensor, or the Comprehensive monitor.
