03’ LX470 w/240k, owned for 6 months.
I’m up for inspection this month and need to take care of the error codes from my scanner.
Codes are: P0134, 0153, 0154 and 0430
Seems like all relate to the O2 sensors. I’ve read that people have replaced 1 or 2, but is it common that all 4, or in this case 3 possibly go out? The P0430 relates to the passenger side CAT, and an often fix is the downstream O2 sensor; but it could be the CAT itself.
If I’m going to replace 3 I might as well replace all 4. Has anyone else had the same issues and is it common.
Also, lights came on about 1 month of ownership.
