Is continuity indicated?Go to Step 4. “BLK/ORN” wire open.
4Check output shaft speed sensor (VSS) signal circuit for
short
1) Disconnect TCM connectors.
2) Check continuity between “PPL” wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is continuity indicated?“PPL” wire shorted to
ground.Go to Step 5.
5Check output shaft speed sensor (VSS) signal circuit for
open
1) Check continuity between “PPL” wire terminal of
disconnected output shaft speed sensor harness side
connector and terminal “C07-25” of disconnected
harness side TCM connector.
Is continuity indicated?Go to Step 6. “PPL” wire open.
6Inspect output shaft speed sensor (VSS)
1) Inspect output shaft speed sensor referring to “Output
Shaft Speed Sensor (VSS) Inspection”.
