Buy OE sensors and you are almost guaranteed to not have an issue. And having worked on the 6.7 power stroke for the last 10 years, despite how dirty they get, the MAP sensors VERY rarely have issues.

Hey Evan, when I had my EGR cooler core replaced, last warranty service as my warranty is now up but she threw a code before expiration, Thank God, the truck service manager mentioned something about a MAP sensor reset process or something like that, because I told him I bought a new Motorcraft MAP sensor and installed prior to bringing the truck in for service. He mentioned that when I picked the truck up because I replaced the old sensor, which I still have...
I was trying to eliminate possible problems... I'm curious to hear your thoughts because I was going to take my receipt with me and go back there to ask that question to get more information. Thanks...

these were all motorcraft…their tolerances seem to be all over the place.
It would be great if the pcm resets or calibrates the new MAP, but it does t…so on these MAPs I did the urban legend disconnect battery trick after connecting these MAPs and the variences were the same…would have been great if after the reset…the out of tolerance MAP was calibrated to zero variance by the pcm using the internal barometric sensor…if it did that…the MAP sensor would always reset to the value of the barometric sensor after the reset.

A biased sensor according to service info is determined by comparing MAP, BARO and EBP KOEO, and seeing if any sensor is more than .65v out of range with the others. You have to consider that the BARO sensor is not always 100% correct so only comparing to that is not accurate. That said, of the data you posted only one sensor is out of range with the BARO. These trucks are very sensitive. If there is a faulty sensor, especially if it is preventing EGR function because of its bias, it will set a code. I have seen trucks over the years that technically had biased pressure sensors in them that had no drivabilty issues at all. The MAP sensors in these trucks rarely fail. I have replaced 2-3 that I can remember in 10 years. One was very biased, like 5psi, one was broken by the customer doing their own repairs and one was in a VERY hotly tuned and deleted truck with a failed CAC. It melted the MAP as well as the plastic upper intake manifold. Cleaned a lot of carbon out of them. Were these purchased from a dealer or sourced on Amazon?

There is no reset for the MAP sensor itself, just clearing fault codes. You can clear KAM if you choose but it is not needed.
