3 CHECK ATF LEVEL
• Start engine.
• Warm up ATX.
• Is ATF level within specification?
(See K12 AUTOMATIC TRANSAXLE FLUID
(ATF) INSPECTION.)
Yes Go to next step.
No Adjust ATF level, then go to Step 8.
4 INSPECTION SHIFT SOLENOID VALVE A AND
C FOR CLICK SOUND
• Perform inspection of operation. (See K26
SOLENOID VALVE INSPECTION.)
• Verify the click sound of shift solenoid A and C
when applying B+ to each transaxle connector
terminal.
• Was click heard from solenoids?
Yes Go to next step.
No Replace solenoid that you could not hear click sound, then
go to Step 8.
(See K28 SOLENOID VALVE REMOVAL/
INSTALLATION.)
5 INSPECT LINE PRESSURE
• Start engine.
• Measure line pressures.
Specification
Idle: 330470 kPa {3.44.7 kgf/cm
2
, 4966
psi}
Stall: 1,1601,320 kPa {11.913.4 kgf/cm
2
,
170190 psi}
• Is line pressure within specification?
(See K6 Line Pressure Test.)
Yes Go to next step.
No All ranges: Replace oil pump, then go to Step 8.
Any ranges: Replace control valve body, then go to Step 8.
(See K34 CONTROL VALVE BODY REMOVAL, K35
CONTROL VALVE BODY INSTALLATION.)
6 INSPECT STALL SPEED
• Measure stall speed in D range.
(See K7 Stall Test.)
Specification
2,0002,600 rpm
• Is stall speed within specification?
Yes Go to next step.
No Replace automatic transaxle, then go to Step 8.
(See K29 AUTOMATIC TRANSAXLE REMOVAL/
INSTALLATION.)
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
approx. 1,200 Hz?
Yes Go to next step.
No Replace control valve body, then go to next step.
(See K34 CONTROL VALVE BODY REMOVAL, K35
CONTROL VALVE BODY INSTALLATION.)
8 VERIFY REPAIR OF DTC P0733
• Make sure to reconnect all disconnected
connectors.
• Clear DTC using WDS or equivalent.
• Start engine.
• Warm up transaxle.
• 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?
Yes Replace PCM, then go to next step.
No Go to next step.
9 VERIFY AFTER REPAIR PROCEDURE
• Perform After Repair Procedure.
