Have they fixed your Sienna? Did they install a new "computer?"
 
My Sienna threw the same code (P0420), and I have found that it could either be a bad catalytic converter or a the engine control module (ECM), as my sensors are good. The ECM's logic has been revised, and if this code appears, your dealer should replace the ECM, free, if your 96/80,000 warranty is still in effect. (Google: TSB EG047-05). I'm stuck though, with 127,000 miles...

Because the CEL usually represents emmission control by euphonium

and because I don't believe in the Liberal Global Warming agenda and don't care if the hippie who is hitch hiking for a free ride breaths any of my exhaust, and lacking respect for the Enviornmental Movement, the CEL light on my cars get very little acknowledgement from me.
 
As long as it runs, step on the gas.

That won't fly if you live where cars are tested for emissions.

And that, my friend, is one of the minor reasons why I live Rural SW WA.
 
After retirement, we considered moving to the Peoples Republic of Puget Sound, but only for a second.
 
Today the road is full of snow while we're comfortable not sliding around the streets of Portland.

You can't pass smog in many states with the CEL light on, and it might also indicate something that might destroy the catalytic. (such as a misfire) Also the light tells you that codes are stored to give you an indication of where to look for the problem.

After the catalytic converter is destroyed, a Flowmaster Delta 50 replaces it.

Not legal in many states, thankfully.
 
Sometimes you can reset the check engine light and it will stay off long enough to pass your smog test, but it's a good idea to have the codes read to see what's going on under there.

Being submissive to the Environmental Movement is like wearing a Tutu on the gridiron.

Okay you tell that to the smog technician, forest ranger, beach patrol and city services personnel in charge of refuse, burning and toxic waste disposal. I'm sure they'll all just let you off.
 
The CEL light should always be addressed regardless if you are in a smog state or not. It could be related to nothing of significance (Ioose gas cap, etc.) or it could be the precursor to your car blowing up.
