Scanner not reading oil pressure?

[Spoolnsquirrels]

Is there a reason i cant get oil pressure to read on my scanner? I have a 411 pcm in s swapped 97 S10 pick up, I sends signal to my guage in my stock cluster and it is only off by about -5 psi so i would have thought the scanner would display it as well?

I dont think any 411 need oil pressure to work so it’s not available to see on the scanner.
