ON-BOARD DIAGNOSTIC
End Of Sie
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): 80 km/h {49
mph}
— Drive in D range, 4th 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 P0734
• 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 5 seconds.
— ATF temperature: 20 °C {68 °F} or above
— Drive in D range, 4th gear
— Throttle opening angle (TP PID): 0%
— Vehicle speed (VSS PID): 50 km/h {31
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
• Are any DTCs present?
• Perform “After Repair Procedure”.
(See K–52 AFTER REPAIR PROCEDURE.)
Yes Go to applicable DTC inspection.
No Troubleshooting completed.
