Hey everyone,
So if it's not one thing, it's another... Exactly a week after buying my 2001 XJ Sport, my check engine light came on. A quick stop at Advance revealed the following error:
P0432
Main Catalyst Below Threshold (Bank 2)
The research I've done thus far has yielded conflicting information (some say it's an indication of a bad O2 sensor up near the pre-cats, others say further down the exhaust system, and so on). I know it's difficult to conclusively identify exactly what's triggering this code, but does anyone have personal experience with this error? And if so, what was your fix? I'm hoping to avoid as much of a wild goose chase on this one as I can, so please share your thoughts. Thanks!
