update - vehicle fixed by dealer, nothing to do with install, see first post- Installed arb compressor now multiple codes and limp mode

[Bweed83]

Put the arb compressor in yesterday and tested everything, went for a drive and everything was kosher. Tried driving today, three miles from home and I get multiple codes
P033f - crankshaft/camshaft loss of sync
P061C - internal control module engine rpm performance
P06A6 - sensor reference voltage 'a' circuit range/ performance
U0401 - invalid data received ECM/PCM a

Checked all fuses and battery/ground connections everything is tight, pulled fuse from arb wiring loom to see if the compressor was causing some issue
Reset everything multiple times and codes keep coming back. Anyone have any idea what the issue might be, it starts slow and sometimes doesn't start at all.


Update,
Just got the vehicle back from the dealership wires under the dash needed to be spliced was rubbing from the factory I guess I have attached a photo of the service ticket in case this makes sense to anyone

details on your installation may help us understand where the potential faults are.

for example, is the arb installed in the engine bay of a 2.3 or 2.7L?
or at the spare tire location?

are you using one of the third party mounting solutions for the engine bay?

what are the electrical arrangements?

2.7 attached are some photos of the wiring arrangement

Check the ground stud to make sure vehicle ground is tight to the body

Check all the grounds around the engine bay cant wiggle them even a little bit bolt is tight as can be, also checked ground and positive posts on battery both tight and don't move

Id say clear codes and see if come back but as a technician the freezeframe data would be erased also making it harder to reproduce

Removed extra grounds from that body ground and cleared codes. They came back right away so it must be something else in the system

Just a observation on the switch assembly. You have it mounted on top of your fuse box assembly. That front mount screw of the switch assembly, what is that screw mounted to? The fuse box lid? Is that screw touching any of the fuses inside?

Did you try a hard reset by disconnecting the battery positive for a few minutes and reconnect?

Make sure you didn’t unplug or damage crank sensor or wiring on lh front of engine

Sorry rh front

low battery voltage? did you test the winch compressor without the engine running?

Made a bracket that is mounted to the fuse box lid bracket it mounted to the lid with small bolts installed where there are voids in the fuse box, switch assembly has been installed for a month or so without issues so I don't think that would be it

It's a compressor not winch, never ran it without the engine running, switch panel is only active when engine is on so it can't activate anything without engine running

Sorry rh front

What does this look like I will check it, though to me it sounds like a voltage issue battery shows 12.4 v when engine is off which seemed low to me but I don't know much about these batteries
