2000 rx300 CEL codes p0330,p1130 and pp1150
 

I recently bought a 2000 rx300 AWD and 3 CEL codes popped up. p0330 knock sensor 2 bank 2, Air/fuel bank 1 sensor 1 and p1150 bank 2 sensor 1. Do i have to replace all of these? I'm wondering if there is something else that could cause these to come up. Any advice/tips are appreciated.

Thanks

I would suggest get them cleared and have them read again on the first onset.

How many miles?

Knock sensors start failing around 130k miles.As the knock code stays on, you will be locked out of overdrive.

Do a search and you will find plenty of discussion on these error codes.

It has 138,000. it started with the knock sensor I reset it, then the other two showed up and the same came up again after another reset. I was wondering if there is something to check that would set off all these or is it just time to replace them?

Thanks for the response Salim
