Long story short. Was getting a P0106, then a P0108 code. Replaced MAP sensor, but fault remains.
Using my scan tool, checked live data from EOBCD, everything looked fairly normal.
However, I recently discovered I could also check live data using the diagnostic mode. (Launch cr919x)
This test concerned me as I was now seeing erratic data on multiple levels, battery voltage from 0 to over 25v, similar on air and coolant temperature, and also manifold vacuum. It was peaking at nearly 4000kpa! No wonder it was throwing a P0108 code!
At first I was suspecting an intermittent wiring short, but after seeing the scan tool data, I'm thinking I have an ECU issue.
I'll post a shot of my scan tool screen. This was recorded with KOEO mode, so static.
Looks like the program won't let me post a pic, file too large?
Anyway, maybe a related issue, also getting a large rpm on startup with engine surging. Only sometimes but quite disconcerting.
So wondering if other members have seen similar issues and what was the fix?
Cheers!
