DP9 - Check Continuity of VSS Harness Circuit

- Key "OFF", Vehicle Speed Sensor (VSS) disconnected.

- Powertrain Control Module (PCM) disconnected.

- Measure resistance between Test Pin 3 at the breakout box and the VSS circuit at the VSS vehicle harness connector.

- Is resistance less than 5.0 ohms?

Yes -- Replace VSS. Remove the breakout box. Reconnect all components. Repeat DP1 to verify elimination of Diagnostic Trouble Code (DTC) or drive complaint. DP1 - Complete VSS Drive Cycle

No -- Service open circuit. Remove breakout box. Reconnect all components. Repeat DP1 drive cycle to verify elimination of DTC. DP1 - Complete VSS Drive Cycle
