Regarding gas caps, the wife's LX470 recently had P0456 code (one associated w/gas cap no longer working as it was intended to - happened to all three of my Toyota's over the past 5 yrs.

I'd take the caps off and put back on and tighten and code would remain or come back. However, once I'd replace the caps w/a new factory cap ($22), code went bye-bye.

So maybe replace the cap instead of just tightening?
