Hey, it turns out that I can.
I programmed the ScanGauge to show data from "Bank 1 Sensor 1" and "Bank 1 Sensor 2". As far as I can tell from the Haynes manual the car has only two sensors... so I'm assuming that's them, even though there were instructions for reading sensors 1-4 in each of two banks.
The data read out is simply an integer value between 0-99. Sensor 2 seems to be working (that is, the data values are changing in a way that makes some sense given engine speed and loading). Sensor 1 has so far displayed nothing but 0. I haven't seen it fall back into CLOSED LOOP since I've been monitoring that data, so I don't know if Sensor 1 might display a valid value in that state. If it does, that would seem to indicate an
intermittent failure to get data from that sensor. I wonder if that's more likely to be a problem with the sensor, or with the wiring?
Thanks for the suggestion!
