I have a P0340 code and I replaced my sensor but to no avail. I could’ve replaced it wrong but I believe it’s a wiring issue. How would I test the wires going to the CPS?

Good morning,

Okay, remove the connector for the sensor and with the key on, put the red lead into the gray/red wire and the black lead into the other wire. Tell me about the voltage.

Do that for both sensors.

I’m getting no voltage for either, could be a fuse? But only one bank 1 is throwing me a code?

No, the voltage comes right from the PCM. You need to go to the PCM and check for power out of the PCM. If there is, then it is a wiring issue. If there is not, then the PCM is the issue.
