TPMS Acting strange

twinturbodude · 10-16-2007, 12:29 PM

So I read this thread the night before last, and then sure enough, the next morning my low tire pressure warning light was on. : ) Stupid TPMS, I thought... then I checked the tire pressure and I was low in all 4 tires (hadn't checked in a while), including being down to like 23 psi in the left front wheel (!). Keep in mind this was at 46 degrees or something in the morning, cooler than it's been for a while. I pumped everything up to 33 front and 36 rear and reset the TPMS through the stalk...it said "Tire pressure low" or whatever, so I just hit the stalk button again and started driving...within about a minute or two the warnings were gone (and the owner's manual said something about how you have to drive a bit to get the reset to complete...I'm sure it averages the pressures it sees as the tires warm up or something).
Looks like the TPMS system actually did the right thing and warned me when my tire pressure was getting too low due to the cold...so maybe it's not all bad after all. : )

Anything that works the way it was designed to, is not bad at all. As a matter of fact, I kind of like having the oil sensor on the OBC rather than checking the oil with a dipstick. It was unusual at first, but now that I'm used to it, I definitely check my oil level more often.

The same happened here, got the alarm drive 10 blocks to gas station checked pressure, all ok. Did the reset, drove awhile all ok.

I can only attribute this to temperature drop.
