Default Loss of power, codes p1125 p1128: Throttle Body Replacement?

I had a problem on my 2002 camry LE V6 where I lose power and the steering
was pretty tight. Took it to the dealer and they said the throttle body
needs replacing to the tune of $1460+ taxes. It was -26 today.

Anyone else have this issue.

Shouldn't that be covered under the powertrain warranty?

Yes, the parts involved are expensive. Basically there's a new
throttle body that replaces the current one. It has a different sized
mounting surface that requires changes in the intake manifold and
throttle body gasket also.

The updated parts address problems caused by sub freezing weather. The
original throttle body motor assembly may respond sluggishly to
computer command in very cold temps, setting P1125, P1128, or P1129
codes. This causes your computer to operate on backup strategy which
limits power until the problem is addressed. If you were to clear ECM
memory and drive in warmer weather, the condition would go away.

This is a 3/36 covered item, unless you are in California,
Massachusetts, or Vermont where coverage is 7/70 (state mandate). You
can call Toyota Corporate Customer Service if the dealer won't give you
out-of-warrantee consideration -- they don't have to, BTW. They may be
more inclined to help if you've done your maintenance there. Assuming
that you're out of warrantee, then you're in "good will" territory at
this point.

If Toyota won't cover it under warranty and the weather has warmed up I'd
just buy a OBD-II code scanner (typical link below) and reset the codes.
Its cheaper, no need to drive to the dealer, and you'll have a "free" OBD-II
scanner to use from here on out.

Those codes refer to this:
P1125 Throttle Control Motor Circuit.
P1128 Throttle Control Motor Lock.
Maybe a wire or connector to this motor
thingy is loose or fell off? Take a look.
What did the dealer want to replace?
I think your steering was just cold making
it tight.
