P015B Check Engine Code

[CrashTestDummy]

Depending on where you are, and what year truck, you should be able to go to just about any local parts houses to get the ECU scanned.

could the code have been misread as P0158?

I found this web page describing this code as a generic code, almost all makes. https://www.obd-codes.com/p015b
I hope it will help you.
