How do you reset the tpms sensors on a 2009 RX350. Did what the manual said, but still flashing.

 

I had the same problem. My TPMS light didn't clear until I drove it a few feet. I'm assuming you checked the pressure in all tires, including the spare.

Hi Jeff

Thanks, that's funny i figured that out after and set the tires to 30psi. But no go lights still on.

As per my manual this is what i did. Set the second set to second or main(button beneath the glove box just pressed it once), then turn the ignition to on not starting the vehicle. Hold the set button under the steering wheel but nothing happens just keeps flashing.

 

The only reason I asked is many people don't check the spare. There are numerous threads with under-inflated spares. I didn't mean to be Captain Obvious.

Good luck,

Jeff

 

I guess no advice on the sensors, do i have to bring it to the dealer or am i doing the reset procedure wrong?

 

Set all tires to 32 psi including the spare. Take it for a drive and see if that gets rid of the warning light. Many members here routinely run their RX tires at 32. If that doesn't work see the dealer.

 

Set all 5 tires to 32 PSI. With the key set to ACC. Press the TPMS button down by the brake pedal. Start car. The light should flash then go out.
