i know...i searched it, but no one seemed to have same problem....well i got my subs, amp, bluetooth, and navi installed this past weekend...it only took them FREAKEN 7 days due to holidays and weekend...but yeah finally got it back and my tire pressure sensor went off...no biggy..i go to get them filled and noticed all are good, cept for back right tire.....round 25 psi....filled it back up to 40 and still my sensor is still on....what should i do...i figure that if i filled them all at correct psi it should turn off RIGHT????

oh well.......ill figure it out......

p.s. never go to the place where i got my stuff installed..worst experience of my life

 

you may just have to reset the sensors or something. Mine was kinda being weird like that and i took it to lexus and they took care of it. No problem

 

TPMS imo is kinda useless when it takes almost 10 psi drop to warn you.
i check my tire pressures on all my cars monthly anyways, i like to have them at the correct pressure, handling and feel is better in my opinion when my pressure is optimum.
