First issue: PRIMARY OXYGEN SENSOR air/fuel RSX Type-S
My issue is I have voltage at my secondary oxygen sensor but its disabled in parameters
my primary oxygen sensor air/fuel ratio 234-9005 Denso oxygen sensor says 0.00 volts -34.00mA
have check engine like for heater O2 heater.
also, I never see 14 volts whether idle or driving and when the car is off battery voltage drops to 11.80 and stays there.
The sensor is only a year old could be junk?
Why would the secondary oxygen sensor show voltage when disabled and non-existant?

Second issue:
In Kpro settings there are units for pressure and vacuum what should the vacuum base be and
and general sensor set up under data logging tab min-max readings?

AEM UEGO Wideband wiring using Hondata K-pro analog cable?

You should try your ECU in a known working vehicle and see if it reads correctly. If it does then the problem is with the sensors or wiring in your vehicle.

The units all depend on your personal preference and what you want to read them in.
