Where are you getting your sensors from? If they are not directly from the dealer they could be Chinese knockoffs. They will look EXACTLY like an oem part, even the box is identical. This is such a problem that cummins has come up with a hologram to put on all genuine parts boxes so we can tell the difference between genuine and a fake.

Non genuine sensors are known to be erratic and unstable.
