So I did a huge brain fart and installed the unit on my subboard reversed.
I’m just looking for steps to verify if I bench test the unit and that it’s good; I don’t know if I fried the sensor or not, but when connected, it shows 10.5 AFR Disconnect the sensor, and it goes 19.9. I don’t have a spare and will buy a new one but before I do that I was wondering if there is something I can test with the multi meter to verify the OEM unit is outputting what is needed to power the sensor correctly.
