Re: Renix scanner port data question.

What you need is a high impedance analog volt meter to read it properly and do it at the sensor in case the wiring is compromised. Not sure yet what the MT-2500 display shows, have not tried mine yet. But if it is a live wave form it should be good for seeing what the signal looks like at the ECU. What the ECU sees, may not be what the O2 sensor data at the sensor is. I would never use a DVM for O2 sensor tests. The data is more like a sin wave.
