We've seen a lot of sensors coming incorrectly wired from new (Delphi in particular)

Have a read of this,it's the sort of thing that's happening

[Astra Mk5/H] [04-09] - Help please

Hi, I have an astra estate, 1.6 petrol. I had loss of power, delayed and intermittent throttle response, and then hunting revs at idle.codes P0130, P0135, P0100. Changed so far: O2 lambda sensor, MAF sensor, cat converter. Being directed towards throttle body now. Any advice welcome. Limited...

Before you jump to any conclusions i need to know exactly which 1.6 engine this is,XEP,XER or XE1,
if you're not sure,post the reg number

Ok that engine doesn't have a maf,just an inlet air temperature sensor,so that's why your app isn't reporting any airflow,
both of your codes are 02 sensor heater so would point to a power feed or earth problem,
i know you say F26 is intact but i would swap it out regardless,i'll get the 02 sensor pinout and post later,so you can unplug and check the voltage at the sensor and check the replacement 02 is wired correctly.

All i can find i'm afraid,pin 3 (red/blue)is the 12v supply

And check there's continuity between 1 & 3 on the sensor itself (should be the 2 white wires)
