DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

7 1) Check transmission range sensor (switch) referring to “Transmission Range Sensor (Shift Switch) Inspection
and Adjustment”.
Are check results satisfactory? “RED/BLK”, “PNK/BLK”,
“RED”, “GRN/ORN”,
“GRN”, “GRN/YEL” or
“LT GRN/BLK” circuit
open or short to ground.
If wires and connections
are OK, substitute a
know-good TCM and
recheck.Replace transmission
range sensor.

shorted to ground.
3 Check output shaft speed sensor ground circuit
1) Turn ignition switch OFF.
2) Check continuity between “BLK/ORN” wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is continuity indicated? Go to Step 4. “BLK/ORN” wire open.
4 Check output shaft speed sensor 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.
5 Check output shaft speed sensor signal circuit for open
1) Check continuity between “PPL” wire terminal of
disconnected output shaft speed sensor harness side
connector and terminal “C35-25” of disconnected
harness side TCM connector.
Is continuity indicated? Go to Step 6. “PPL” wire open.
6 Inspect output shaft speed sensor
1) Inspect output shaft speed sensor referring to “Output
Shaft Speed Sensor Inspection”.
Is check result satisfactory? Go to Step 7. Replace output shaft
speed sensor.
