Check Engine Light On.. Code Says Thermostat malfunction
I've had no issues with the temp going up or any other engine problems.. any experience with this? Is there a way to diagnose/replace myself without getting raped in the shop? Please let me know if you've had any experience with this. Thanks!

This is written in the shop manual.
But just replace it because the thermostat is only $30.
Testing the existing one will cost you more time and money....

You can buy thermostat at local parts store for $10 - $12

As suggested replace the thermostat. Alhough you did not provide the code most likely it was because it did not reach operating temperature in the proper timeframe. In other words it's getting lazy!

I didn't realize that, sorry man. (being sarcastic here)Actually aftermarket parts have to meet or exceed OEM ratings, most decent brands do that. I certainly do NOT suggest buying a Fram oil filter for your Lexus but you will have great results with Napa Gold or Wix as these parts meet or exceed oem quality specifications.
If you get your car into bodyshop, do you ask them if they can buy paint from Lexus?

The thermostat, and cooling system are also part of the fuel system in that the PCM uses the input from one of the coolant temperature sensors to adjust the fuel/air mixture. You should stick with OEM components for the fuel (system) , and also the cooling (system) since they both need to be accurate. If you get the Toyota part number for an OEM replacement thermostat and o-ring gasket, you can purchase the OEM Toyota components on ebay.com, or amazon.com for less than the dealer would charge. Some Toyota/Lexus dealerships sell components on ebay for a reduced cost.
