Troubleshooting
Step
1 Was "Automatic Transaxle Diagnostic Flow
Table" in this section performed?
2 Check Output Shaft Speed Sensor (VSS)
Power Circuit.
1) Turn ignition switch OFF.
2) Disconnect output shaft speed sensor con-
nector.
3) Turn ignition switch ON.
4) Measure voltage between "BLK/RED" wire
terminal of disconnected output shaft
speed sensor harness side connector and
ground.
Is it 10 – 14 V?
3 Check Output Shaft Speed Sensor (VSS)
Ground Circuit.
1) Turn ignition switch OFF.
2) Check continuity between "BRN" wire ter-
minal of disconnected output shaft speed
sensor harness side connector and ground.
Is continuity indicated?
4 Check Output Shaft Speed Sensor (VSS) Sig-
nal Circuit for short.
1) Disconnect TCM connectors.
2) Check continuity between "YEL" wire termi-
nal of disconnected output shaft speed
sensor harness side connector and ground.
Is continuity indicated?
5 Check Output Shaft Speed Sensor (VSS) Sig-
nal Circuit for open.
1) Check continuity between "YEL" wire termi-
nal of disconnected output shaft speed
sensor harness side connector and termi-
nal E12-25 of disconnected harness side
TCM connector.
Is continuity indicated?
6 Inspect Output Shaft Speed Sensor (VSS).
Inspect output shaft speed sensor referring to
"Output Shaft Speed Sensor (VSS) Inspection"
in this section.
Is check result satisfactory?
