My '04 Toyota Sienna with 150K miles tripped a check engine light.
Got codes read at auto parts place:
P0420 P2238 P2241 P0420 P0430 (they said the P0420 has triggered several times)
I note that the engine light came on just after a big dip in winter temperatures (dropped to 13 degrees).
Here are my questions:
Thanks!
