I am working on getting the diag chart for you. having some technical difficulties. I am gonna reboot and be back in a few.
Didn't want to leave you waiting and wondering.
A scan tool is needed to observe the crank and cam signals and spark advance settings in the PCM.
Still having problems, my website for my service information is currently down, I will keep trying and see if I can post it later.
In the meantime if this code appeared out of the blue and it is the only code you are receiving, I would do the preliminary checks listed above in my first post which is part of the diag chart anyway.
Sorry for the delay
Not likely the crank is in the front timing chain cover and the tip is constantly splashed with oil.
It may be intermittant I would clear and see if it comes back, A jarring from the trailer may have set the DTC.
I got the diag chart click below and related schematic.
