87 V1500 Oxygen Sensor Values in WinALDL

[xylorex]

I keep getting a error 13 code, which is Oxygen Sensor in WinALDL. I've reset the computer a few times and it keeps throwing the code. Of course, I changed the sensor first, but the code keeps coming back.

This morning on my way to work i put the laptop on the seat and monitored the o2 sensor values in winaldl.

~0.445-0.6v when started and while it warmed up, and sitting in traffic.
~0.6-0.85v while i was accellerating onto the interstate
~0.1-0.3v while cruising 65-75mph

Seems like is working to me. Anybody have any ideas what the problem might be?

Any input is greatly appreciated.
