Default New help with PLX M250 & 02 Sensor Issues

My PLX M250 stopped outputting data to EFILive. PLX believes the M250 died. I am not sure. Trying to figure out how to test WB to make sure that my problem is not an 02 sensor.

FWIW, the WB sensor is not permanently mounted. I install and remove when not tuning.

Any help would be appreciated.

only thing you can do is verify 12v input and good ground to M250 and try another O2 sensor...good luck

I don't use it to often. Last time in October, I was getting power off lighter adapter. The adapter broke and I threw it away.

Two months later, I tried to wire M250 off ext1. Real dumb but it shows it in directions. It finally hit me I needed to buy a new lighter adapter
