What year is your sc300 or sc400?
Code 29 is the sub o2 sensor, so you replaced the one on the cat right? The 2 on the exhaust manifold are the main ones.

I believe the sc400 has 2 sub o2 sensors. Did you replace both of them?

Maybe the other side was bad or both. Can't tell unless you test them.
