P1516

[GoBlueHummer]

CEL came on during my commute this morning, code reader told me it was p1516. Truck was running fine and I didn't get the "reduced power" message in the DIC. My TB is probably due for a cleaning. Wondering if anyone has had experience with this code? It's colder today than it has been in a while and I am wondering if that is contributing to the code popping up.

Thanks

Haven't found P1516 yet, but B1516 sounds like a Battery current reading, so with it being cold, perhaps the battery is going bad
