'91 D150 Speedometer/odometer not working

Speedometer/odom not working. traced wiring from speed sensor to computer and gauges, has continuity. Replaced speed sensor, checked spdmtr head gear, looked fine, checked sensor, produces voltage. Weird thing is, disconnected sensor and drove a few miles, then did fault check and got no code about speed signal. Thought that would show me if there were a problem with the wiring after the computer, since it didn't come up before, but still didn't come up. Is this evidence of a problem w/the computer?
