low tire pressure light

I just bought 4 stock tacoma wheels and tires with the sensors still installed, mounted and balanced them, my pressure is fine, but when ever I leave the house and travel a bit, my low pressure light comes on, what do I need to do???

 

Does it flash and then come on or just come on solid??
Flashing means it is registering a sensor(s) as failed. Solid means low pressure. If you bought those new wheels with different sensors than were in the truck...You need to get the new sensors programmed into the TPMS computer-That's a trip to the dealer and 80-90 bones from what I have heard.

 

The new sensors have to be programed to your truck, I imagine you still have your original tires and rims sitting around, and when you are at home they connect to them, but when they go to cycle the pressure information after you have left home the light comes on.

 

It could also be your spare tire

 

It flashes for a minute of so, then stays solid, guess I'm taking a trip to the dealership, damnit!!!

 

Thanks for your help guys

 

Try setting all FIVE tires to door jam specs, push and hold the reset button then turn the ign to on, wait for the tire light to blink three times. This resets the base pressure. If the light comes back on, take it in.

 

Door jamb pressure doesn't matter- Just as long as all 5 are the SAME pressure (or very close) it's good to go- That button will reset it.

BUT the OP has a FLASHING light first-That means sensor malf....and with a new set of tires...Once he gets far enuf (distance and time) away from the old tires- The light goes off.
