Hi,
I keep getting this code for Cylinder 5 "B" circuit open. I clear the code, but in a few days later it comes back. This is a pending code and a permanent code.
I cant tell if this is an injector problem or a wiring problem. Which injector is circuit "B"? The direct or the port injector? How long does it take for the permanent code to clear?

Sorry for the long question

TIA

Injector B is a direct high-pressure injector under the intake Manifold for cylinder 5.
Open circuit detected.
You can't clear an open circuit fault just by clearing a code. Those electrons are not yet smart enough to jump the open fault.
Good luck.
