Ok so ive been having code issues with my o2s for about 4 months now, ive replaced o2's and spark plugs and just cleaned my MAF and ran seafoam through the system but codes p0130, p0150, p0133 and p0153 keep coming back... now after i did the spark plugs these codes went away but now they are back again....

In addition to cleaning the MAF and using seafoam... my abs light now rapidly flashes...

163k miles on the car with timing belt alrdy done. and all regular maitnance finished like it should be

im lost on what else it could be. any help would be great

Thanks, tauzins

 

I received very similar codes when I first purchased my car. The CEL light was on and the indication was the Catalytic Converter based on the codes I was receiving. I attempted to use known working O2 sensors in all of the bunges on the Cats and the codes continued to be thrown. I decided the next course of action was to replace the Catalytic Converters, as there are 2, or three I can't remember, of them. Once I did this and used Spark Plug Defoulers to trick my ECU into a correct reading the issue went away.

I can't say that this is exactly what is wrong with your car, but if you truly want to find out take it to Lexus and have them run some tests on it. Or, do some research online and see what others are saying. I found the internet to be a valuable tool when trying to figure out the course of action.
