06 tC, 96xxx miles, auto.

What could be the reason?

Was driving and randomly the lights came on, the (!) light is flashing...when i turn the car off, all the lights disappear, but comes back on in a day or so.


Checked multiple threads...and checked up the brake fluid level (which is fine), tire pressure is fine, what could be the culprit?

_______

 

I would see if there are any trouble codes (Toyota calls them DTC, diagnostic trouble codes). Autozone can hook up a code reader.

I know on the 05-06's they measure the tire pressure by using the ABS sensors, the later years have transmitters mounted inside the wheels to measure the air pressure.

Could be a faulty ABS sensor/wiring. check to see if you have any codes first.

check to make sure all your ABS sensors are plugged in correctly and no wires are torn... i got the same lights a while back and it turned out that the ABS sensor wires on the right rear tire were torn...

 

where exactly are the ABS sensors located?

 

take the wheel off and look behind the dust shield of the brake rotor. The sensor is right next to the axle. Wish i had pics to help you out better.
