Re: AF30 Halmeter and Oxygen sensor.Thanks Brian and others! 700 1988

Your right, Gene. My concern was that there is a short between the inner wire and the shield.

If there is no 0.5V on the green wire when the O2 sensor is disconnected (black wire disconnected from the green wire at the connector by the firewall) and the ignition on, there is not much hope that the O2 sensor will read properly when the sensor is reconnected.

The readings he is getting are low (lean), although as you mentioned at least he is reading SOMETHING, so maybe there is another problem I'm missing. If he can't get 0.5V, there may still be a short, or less likely the LH computer is misbehaving.

A bad O2 sensor should show up in the computer trouble codes as well.
