Your Air/Fuel Ratio sensor is failing. It is also called the Bank One sensor. The sensor itself is about $200 from a parts distributor and somewhat more than that at a Lexus parts department. Labor to remove the old sensor and replace it with the new one will also run you several hundred dollars.
If you're mechanically inclined, you can tackle this repair yourself. But you must first determine the exact location of the failed sensor. And be careful not to strip the threads in the manifold when you remove the old sensor. Let me know if this helps and please rate this solution. lone99star

p1130= bank one sensor one, Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (sensor is located underneath near the firewall)
p1150= bank two sensor one, Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Directly behind the radiator)
p1135=bank one sensor one, Air/Fuel Ratio Sensor Heater Circuit MalfunctionBank one sensor one sensors run around $206 Bank two sensor one sensors run around $150 basically its o2 sensors if your mechanically inclined its a good weekend job to tackle yourself and safe a couple hundred dollars in labour, you would need to invest in an o2 socket and some pbblaster penetrating lubricant to get them out..hope this helps you and dont forget to rate if it does help thanks
Was the computer reset after the thermostat was replaced?? If not, it must be reset to clear prior codes. as for the p1130/1135, they are related here is some info>>>>http://www.engine-light-help.com/toyota-engine-light.html
P1130 Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction (Bank 1 Sensor 1) This sensor is the hardest to get at. It is between the cat and the cylinder block on the bank of cylinders closest to the firewall. Not much wiggle room back there. Sensor will run you about $225 from Toyota, $275 from Lexus, but you may be able to get a Denso sensor on line. Good luck and hope this helps. keep me posted.
Check for vacuum leaks. ie, vacuum lines them selves, the rubber tube that runs from the air filter to the throttle body. If it has a plastic intake manifold, possibly the rubber port seal gaskets between it and the engine. Lean codes are set when the PCM isn't monitoring all the air coming into the engine (vac leak) or low fuel pressure.
no such thing as a catalytic computer... there is a catalytic converter ... part of the exhaust system so they may now be "guessing" that it's an O2 sensor. take the car to autozone... they will scan the codes for free.... post the codes here tho the lads and lasses there are pretty clever and will probably tell you what the codes mean.
The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms
