P1130 & P1150 Error Codes

[PailsBill]

I keep getting P1130 and P1150 error codes. I took it to a Toyota dealer and they said they can't find anything wrong. I doubt both sensors are bad. What can cause these errors? 2001 RX300 130K miles

This is an excellent site and though it takes a little wandering and sorting, you probably can find some good help there. http://www.obd-codes.com/trouble_codes/lexus/ They have section that will tell you the probable cause and fix for those codes. I realize what the codes say, but there is more help , including forums for specific codes (that's a little loose). I believe the page I linked is the Lexus specific page, but branch out from there. Good luck!
