I have a 2008 Serria 2500HD, in the morning when it's cold, I get a warning on the dash, "check right rear tire pressure", some times it also says "check the left tire". I did check and it's fine. After driving a short time all warnings go out. Anyone have similar issue's?
 
Mine does the same thing. I researched it a little and found that my truck calls for 35 psi in all tires. When the weather is cold, the tires tend to show less air pressure.

I had been running mine @ 32 psi. When I raised all tires to 35psi, the lights went off. They will come on when there is a 5psi variance from the 35 figure. Meaning they will come on when tires go below 30psi and over 40psi

Hope this helped....
 
this is one of the few things about my truck that I hate. Living in Canada the temps vary quite a bit and my light is pretty much on constantly.
Next spring I'm going to do what the off roader guys do and put all the sensors in a pressurized tube and zip tie it under the back seat.
 
According to a friend who works in a Dealer this is one of the biggest headaches they have. He said, hardly a day does not go by when someone calls or comes in complaining that the TPS is giving them false warnings.

My 2010 GMC has come on about 100 times in the last year and all the dealer will do is say, its normal yet my 2009 Cadillac has the same system and has not giving me any problems in 3 yrs.

How is that going to stop it? If the sensors can not communicate with the TPS it will trigger the warning on the dash. Each sensor is assigned to a wheel and the TPS will throw an error if you do not reprogram it after tire rotation.

I could care less what tire the sensor thinks it's on..it will stop them from warning me every time the tire pressure drops a friggen pound or two like it does now.
They will all be in a sealed tube pressurized to 40 psi. I might even zip tie it under the dash close to the heater so in the winter it will warm up faster.
 
Good luck with that. Once you take them out of the wheels the system will throw a "Service Tire Pressure Warning System" message in the DIC and turn on a yellow warning symbol on the dash. It will also keep doing this over and over until the problem is corrected. So if you don't mind hearing a ding ding ding and then a warning message every 5 min of driving, go ahead.

I have never had an error from not reprogramming which is a PITA. The system thinks the tire effected is still in the same location which is not correct but I know it is now on the front or rear instead of where the TPS was assigned. The pick up for this system is not near the individual tires but centrally located. The separate tube system does work if the sensors can be read through it.

Exactly..my tires have been rotated and the sensors never reprogrammed...it tells me the front right is low..but it's actually the front left.
 
New Sierra Warnings

Yes,

If you bought new tires, make sure sensors are working.

I had similar experiences with my 2011 Sierra when I bought it. Tire pressure was readjusted a couple of times, and sensors seem to be OK now. Check tire pressure and fill when cold, if doesn't fix, might need new sensors.

Another thing to keep in mind is that the tire sensors in the wheels have a tolerance of 1-5lbs. Just like most tire guages you buy. Buy a bunch of tire guages from any source and see how many read the same.

It is a shame we now have laws and these little lights to tell us what is happening since some people never do anything but get behind the wheel and drive, then crash, roll over and we get to put up with the results.

If they were set at 10 pounds then I could live with that...I check my tires along with everything else...and like you said..because of people that don't..or manufacturers that screwed the pooch..we pay..
