I just tried to replace the oxygen sensor in my 81 toyota pickup SR5 but couldn't find it. It looks like the intake manifold has a blank spot right where the sensor should go. Does anyone know what is going on? Did someone put an aftermarket manifold on to eliminate the o2 sensor? I looked around and could not find the wiring harness for the sensor. Did 1981 toyota's have o2 sensors at all? Any info would be appreciated.
have the same problem?
