Default P0150 code

Hi everyone, I keep getting a p0150 code, looking online it says it’s the bank 2 number 1, am I correct that that is passenger side front?

Yes, passenger side (US, LHD), pre-cat.

Same issue here, but... It's not the O2 sensor - All 4 have been replaced.
- Cleaned the connectors
- probed to verify continuity between the upstream connector and wires
- Opened the umbilical that crosses the firewall on its way to the cabin ECU and probed for continuity
Now, in that bundle I find only the wires for the O2 heater, but not the signal wires. Where do they go? RAVE indicates the ECU, but either they have both lost continuity or they go somewhere else.
Thanks

Have you viewed live data from the sensors? It's not unheard of for them to be dead out of the box.

My ODBII scanner is pretty simple, it doesn't offer that data. However, the two upstream sensors were replaced by an indy 3 months ago. Four new Bosch sensors were a lot less than what he charged for the two, so I just swapped them all out. Chances are slim that it's a bad sensor.

Bosch sensors were showing an extremely high rate of failures out of the box. I wouldn't automatically exclude that as a possibility.

Thanks. The values are similar when compared to the two I just pulled out: All give very similar readings. I have to assume it's electrical, and there is an issue with the signal wires I can't locate closer to the ECU - Or do I?

Page 17-2-14 of the RAVE shows you all the pins on the ECM, and tells you which wire colour goes to each one as well as which O2 sensor it comes from. You should be able to test for continuity all the way to the box.

Thanks, I'm still getting to know RAVE. I read all of it and got into section 18 as well for more into.

Referring to Sandman's post on loose pins, and a PM exchange, I checked continuity to ground on the ECM itself: All good. I pulled the ECM in diligence and its clean as can be.
An OBDII upgrade gives data stream: Both Bank 2 Sensor 1 & 2 show no activity.

What would shut down Bank 2?
