Catalyst Monitor Not Ready

Topic starter

2002 Solara V6 1MZ-FE Engine 113k miles.

I replaced a dying battery back in July. Now the catalyst monitor shows not ready/inc for smog check. Everything else passes. Been trying different drive cycles and so far nothing is working.

Did you load test the battery and alternator? The low input from charging system can be an issue. Also, do you have any check engine light?
