    91 civic code 4 dohc zc

    When I checked continuity of the sensor it was not plugged into anything. As I read later, showing continuity WAS a sign of a problem (you are right, should not show 0 ohms). I did replace the sensor, but still same problem. The extensions added for the sensor are just similar wire to what was...
