Hi,

first please excuse my English - I'm from Germany.

I’ve got a 2018 Camaro SS.
LT4 Supercharger conversion
BTR Stage1 blower cam
Breakout harness from maf to map
Tuned
Current setup since nearly 1 year
At first with a CAI and now with the stock airbox since 4-5 month.
Only table changed from CAI to stock airbox was MAF.

Since about a month following happens:

On every drive there's trouble code P0106 when I read it with my MPVI3
I only began checking this, because sometimes it's throwing a CEL, because of that.
CEL isn't always on and can be deleted. The fault code stays and can't be deleted.

Sometimes there's also U0401-71. I don't know if this triggers the CEL or of it's triggered through continuous P0106.

On top of that more less the oil pressure also shows zero but pressure is there. See also attached picture. Note: metric scale

When oil pressure is showing zero my mpvi3 with TDN app isn’t working anymore. So I’m not able to log or read dtc.

I already sprayed the whole motor and intake with brake cleaner to locate any vacuum leak but nothing found.

Today I disconnected the breakout harness and did a continuity test to it with a multimeter. All ok.
I couldn't test it for 5v or grounding, because I didn't have the little test probe pins for the plugs at the moment.

Ignition was off the whole time.

After a start it threw me various errors and a CEL. See attached screenshot.
I was able to delete all of them but P0106.

Could the map sensor be the problem and cause also a shown zero oil pressure and no working mpvi?

Or do anybody have an idea?

Nobody?

You could try reposting this in either the tuning or forced induction sub-forum.
You have a lot of modifications.
