DTC P0500 (VSP) - VEHICLE SPEED SENSOR (VSS) MALFUNCTION Subaru Outback BG

If speedometer operation is abnormal, check power supply and ground circuit to combination meter and harness connector between combination meter and vehicle speed sensor (VSS). Repair or replace parts as necessary. If speedometer operation is normal, go to next step.
Turn ignition off. Disconnect TCM harness connector. Turn ignition on. Using DVOM connected to chassis ground, backprobe ECM harness connector terminal No. 83. See appropriate wiring diagram in the «WIRING DIAGRAMS»(ref-26255) article. If voltage reading is less than 2 volts, go to next step. If voltage reading is 2 volts or greater, check for open in harness between ECM and combination meter connector, poor contact in ECM connector, poor contact in combination meter connector or poor contact in coupling connectors between ECM and combination meter connector.
Turn ignition off. Disconnect ECM harness connector. Check resistance between ECM harness connector terminal No. 83 and chassis ground. If resistance is greater than 10 ohms, repair poor contact in ECM connector. If resistance is 10 ohms or less, repair short in harness between ECM and combination meter connectors.
