I Just Don't Get the TPMS Sensors
So a few weeks ago I got new TPMS sensors from my tire shop since the old ones had died. The first problem is they measure 5 pounds less than actual reading(i've tried 3 different gauges). The stock ones measured 3 less than actual. The second problem and this is what I don't get. I believe the system is set up for 33/39 and to give an alarm if the pressures are -4 pounds. THe last few mornings it's been a little colder so my fronts were reading 29 pounds(34 pounds is the actual reading with a gauge) which set off the alarm. Around lunch after its warmed up the reading is back up to 30, so i reset the system but the alarm goes off still. I don't get it?

Mine read about 2 lbs low up front and about 4 lbs low in the rear. As long as the alarm isn't going off its fine. It's just a guide to confirm that all is well and that the tires are up to temp.

No idea, mine read 30/31 fronts depending on amb temp and 33/34 rear.
My actual pressures are 33/37 cold at 68 degrees.

Do you have the load set at full or partial? That will effect it.

I have a digital gauge that I bought, I don't remember where. I've compared it to two different long acre fluid filled gauges and read within half a pound difference.
