Archived code 2127 throttle position sensor low voltage

[KPrellwitz]

My 04. 5 is throwing a code # p2127. From what I can tell this reads as throttle position sensor low voltage. I havnt taken it to the dealer yet. I dont want to if I dont have to. The light seems to only come on when its below 40 degrees outside. It seems to keep the transmission from shifting into overdrive. Just a shot in the dark but has anyone else had this problem yet?

My 99 does the low voltage APPS code on a regular basis when the weather gets cold. Even though I live in Calif. it still gets down into the teens at night and if I move the truck in and out of the shop a couple of times without driving enough to recharge the batteries it will set the same code or, the last one was a 1291. Intake air temp does not change when heater is cycled. I just clear the codes and get a good charge on it and it usually doesn't come back for a long time. Does not affect the way mine drives. You can check and make sure the batteries are not getting tired.
