Tire pressure sensor in 2008's

[blackhawk29]

My TPM is all over the place. since the cold weather it shows low pressure readings on all tires. The DIC just keeps showing low pressure warnings on all the tires. I of course have them inflated to proper levels. They should have filled the tires with nitrogen at the factory, or wrote a better program for the ecm to factor in cold weather changes. I just ignore it.

Depending on how much the temp is changing where you live pressures can vary up to 5-10 psi on that size of tire once the tires are warmed up. Try setting them at 42 cold, increased pressure wont turn the light on as they are looking for low tire pressure as long as they all increase even. If it is telling you one tire is way more inflated but they all read the same on a gauge, the sensor that is reading high is fubar and needs to be replaced. Hopefully these systems get better with time cause all vehicles will have them soon.

Humtech...thanks for the info. I'll keep an eye on that sensor thats throwing the high pressure warning. If it keeps throwing the warning, I'll take it back to Cochran Hummer and have them replace it. Hope all is well with you!

Not much yet, just a light drop here and there but today dropped down to what felt like -20c but is supposed to warm up overnight, we'll see.
