Did your P0420 issue get covered by Toyota, under their emissions warranty?

If so, what parts did they replace? (There's a TSB to R&R the ECU when P0420 comes up on these Siennas).

Thanks!
 
nope, toyota did not warranty it. forked out 300 to get it fixed. family friend helped us...

The oem sensor was seized...odd how its a california car too with 40k miles on it
