STEP
3 CHECK ATF LEVEL
• Start engine.
• Warm up ATX.
• Is ATF level within specification?
(See K–12 AUTOMATIC TRANSAXLE FLUID
(ATF) INSPECTION.)
4 INSPECTION SHIFT SOLENOID VALVE A AND
C FOR CLICK SOUND
• Perform inspection of operation. (See
SOLENOID VALVE
• Verify the click sound of shift solenoid A and C
when applying B+ to each transale connector
terminal.
• Was click heard from solenoids?
5 INSPECT LINE PRESSURE
• Start engine.
• Measure line pressures.
Specification
Idle: 330—470 kPa {3.4—4.7 kgf/cm
psi}
Stall: 1,160—1,320 kPa {11.9—13.4 kgf/cm
170—190 psi}
• Is line pressure within specification?
(See K–6 Line Pressure
6 INSPECT STALL SPEED
• Measure stall speed in D range.
(See K–7 Stall
Specification
2,000—2,600 rpm
• Is stall speed within specification?
7 INSPECT FREQUENCY OF INPUT/TURBINE
SPEED SENSOR WHEN DRIVING VEHICLE
• Turn ignition key to OFF.
• Connect WDS or equivalent.
• Start engine.
• Measure frequency of input/turbine speed
sensor while driving vehicle under the following
conditions:
— Vehicle speed (VSS PID): 60 km/h {37
mph}
— Drive in D range, 3rd gear
— Throttle opening angle (TP PID): about 25%
• Was frequency of input/turbine speed sensor at
appro. 1,200 Hz?
8 VERIFY REPAIR OF DTC P0733
• Make sure to reconnect all disconnected
connectors.
• Clear DTC using WDS or equivalent.
• Start engine.
• Warm up transale.
• Drive vehicle under the following conditions for
more than 2 seconds.
— ATF temperature: 20 ° ° ° ° C {68 ° ° ° ° F} or above
— Drive in D range, 3rd gear
— Vehicle speed (VSS PID): 4 km/h {3 mph}
or above
• Are any DTCs present?
9 VERIFY AFTER REPAIR PROCEDURE
• Perform “After Repair Procedure”.
(See K–52 AFTER REPAIR
• Are any DTCs present?
