Hello guys, please I need help. I got a used 2010 lexus es350 with p0157, p0158 p0037, and p0441 and p0420. I was told there was cat inside but after checking, I discovered that the cat was removed. I have replaced the bank 2 sensor 2 but it didn't fix any code. I have replaced the purge solenoid and canister purge valve, it didn't fix the p0441. I have examined the exhaust and I can't seem to find any leaks.
I took the car to an electrician and he said all the problems will go away once I replaced the catalyst.
Replacing catalyst is extremely expensive in my country and i plan to fix oxygen sensor spacers on both downstream sensors..
Please, has anyone experienced this issue before and what they did to fix it. Also will Replacing the cat clear all the above codes?

First, I would put the spacers on both post-cat sensors.

Thanks a lot, does that mean that you also believe that the absence of the catalysts causes all the codes? I really appreciate your input, I have ordered for the spacers and also ordered for brand new downstream sensors (234-4064, and 234-4260). I will replace the sensors again and the spacers and give feedback.

The Sensor 2 monitors the CAT, and if there's no cat it will report it.
I know that P0420 and P0430 are active only when the catalyst efficiency is below threshold, that means no cat or bad cat.
With the spacers you will eliminate that code.
The other code you have is the O2 bad heater. In that case the sensor has to be replaced.

Regarding the P0441, you have a leak somewhere. Check the gas cap o-ring for cracks. Also, when you close it, turn it until you hear one click.

Did you check the wiring of the B2S2 sensor?
There may be a bad wire or a bad sensor.

Do you have the freeze frame data?
