Hi.
Could someone tell me what their daignostic scanner reads for this live value please.
I’m getting 14.5psi with the engine off.
Reduces when engine idling to 5?
And when sensor disconnected, reads 20
Thanks.
Confirmed with 2 scanners (for engine not running value)
We live at the bottom of the ‘air-ocean’ at approx ONE BAR (14.5038PSI).
Your reading is correct!

So why do turbo / vac gauges read 0 when not connected

They’re calibrated to read “0” at atmospheric pressure. Think of the gauge as a device to read values above and below atmospheric. The computer just wants an absolute figure for its calculations.
