Hello, I just bought an 06 IS 350 recently and my TPS light came on (now flashing) along with a warning light.
I read that this is probably due to a sensor that is broken or has a low battery. I have the tires set at the PSI I want, I just don't want to look at the flashing lights anymore. Can someone give me a step by step on how to turn those lights off?
I would do it myself but the car didn't come with an owners manual, and the one I ordered won't be here for a couple weeks.

 

There is no way of just turning off the flashing warning light. You have to replace the TPMS itself. Seeing your car is 9-10 years old, it's probably a dead battery. Either replace them all with a new aftermarket set and install into the wheels OR DIY a "pipe bomb".
