Description
The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of the CVT output shaft and emits a pulse signal. The pulse signal is transmitted to the TCM, which converts it into vehicle speed.

DTC CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
NOTE:
If "DTC CONFIRMATION PROCEDURE" has been previously performed, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test. 1.CHECK DTC DETECTION
With CONSULT-III
Turn ignition switch ON.
Select "DATA MONITOR".
Start engine and maintain the following conditions for at least 12 consecutive seconds.
ACC PEDAL OPEN : More than 1.0/8
RANGE : "D" position
Driving location : Driving the vehicle uphill (increased engine load) will help maintain the driving conditions required for this test.
Check voltage between output speed sensor (secondary speed sensor) harness connector F23 terminal 1 and 3.
Check voltage between output speed sensor (secondary speed sensor) harness connector F23 terminal 3 and ground.
Is the Inspection result normal?
YES >> GO TO 3.
NO-1 >> Battery voltage is not supplied between terminals 1 and
3, terminals 3 and ground: GO TO 6.
NO-2 >> Battery voltage is not supplied between terminals 1 and 3 only: GO TO 8. 3.CHECK HARNESS BETWEEN TCM AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)
(SENSOR GROUND)
Turn ignition switch OFF.
Disconnect TCM harness connector.
Check continuity between TCM harness connector F16 terminal 7 and ground.
Is the Inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace damaged parts. 4.CHECK HARNESS BETWEEN TCM AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)
(PART 1)
Is the Inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace damaged parts. 5.CHECK HARNESS BETWEEN TCM AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)
(PART 2)
Check continuity between TCM harness connector F16 terminal 34 and ground.
Is the Inspection result normal?
YES >> GO TO 10.
NO >> Repair or replace damaged parts. 6.CHECK HARNESS BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR) (POWER) (PART 1)
Is the Inspection result normal?
YES >> GO TO 7.
NO >> Repair or replace damaged parts. 7.CHECK HARNESS BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR) (POWER) (PART 2)
Check continuity between IPDM E/R harness connector F10 terminal 58 and ground.
Is the Inspection result normal?
YES >> Check the following.
Harness for short or open between ignition switch and IPDM E/R
10A fuse (No. 34, located in IPDM E/R)
Ignition switch NO >> Repair or replace damaged parts.
8.CHECK HARNESS BETWEEN TCM AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)
(SENSOR GROUND) (PART 1)
Is the Inspection result normal?
YES >> GO TO 9.
NO >> Repair or replace damaged parts. 9.CHECK HARNESS BETWEEN TCM AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)
(SENSOR GROUND) (PART 2)
Check continuity between TCM harness connector F16 terminal 7 and ground.
Is the Inspection result normal?
YES >> GO TO 10.
NO >> Repair or replace damaged parts. 10.CHECK TCM
