low tire pressure warning light?

[thomasugenius]

I know this has been a thread in the past, but I still am not able to resolve this issue...
I changed all tires on my 04 4Runner to Revos 2000 miles ago, including the spare. Just last week, the light came on and stayed on and then started blinking... I checked all tires and made sure tire pressure was set at 32 psi for all 5 tires. Is there a reset button or anything I can do myself? I'd rather not have to take the rig into the dealer if I can avoid it. Thanks in advance for the responses out there~

Flashing indicates there is a problem with at least one of the sensors if not all of them.

You did put the RF sensors back on the stems when you changed tires, right?

Hummm...I'm not sure what the RF sensor is?? But I imagine so, considering the tires were replaced 3 months ago and the light started blinking 3 days ago. Would you agree the sensors (valve stems) were replaced then? I learned from the dealer that tire pressure must be within 2 psi of each tire or this thing will go off. I have checked this 4 times now. All at 33!?!

CMiYC is correct. A flashing light means a problem with the system. Either one or more of the sensors is bad or another part of the system (wiring, sensor pickup, etc.) is bad. A dealer would probably be needed to pinpoint the exact cause.

Did you change rims as well or just the tires? If you just changed the tires, it should still be covered under warranty.

There are other things that might cause it, such as new devices that output similar radio frequencies as the sensors. Do you have any new electronic devices installed? Any work around the wiring?

I just changed out the tires, not the rims. So I guess in the shop she goes. Thanks for the info all~
