Hi guys. Got a problem with my RX400H 2007.

I had a P0137 code (heated oxygen sensor, bank 1 sensor 2 low voltage) so we replaced the O2 sensor with Febi Bilstein part number 175843.

Now I have a new code, P0420 catalytic convert system bank 1 efficiency below threshold.

Any ideas?

P0420 is often caused by an exhaust air leak so I would make sure the sensor is correctly seated and torqued down correctly and that you didn't flex the exhaust and put a hole in it somewhere when you removed/installed the old/new sensor.
