P0730 INCORRECT GEAR RATIO
DescriptionINFOID:0000000005928815
TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signal. T hen it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005928816
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005928817
• This is not an OBD-II self-diagnostic item.
• TCM calculates the actual gear ratio with primary speed sensor and secondary speed sensor.
• Diagnostic trouble code “P0730” with CONSULT-III is detected, when TCM receives an unexpected gear
ratio signal.
Possible CauseINFOID:0000000005928818
Transaxle assembly
DTC Confirmation ProcedureINFOID:0000000005928819
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Make sure that output voltage of CVT fluid temperature sensor is within the range below.
ATF TEMP SEN: 1.0 - 2.0 V
If out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to
increase the voltage (c ool down the fluid)
3. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
4. Start engine and maintain the following conditions for at least 30 consecutive seconds. TEST START FROM 0 km/h (0 MPH)
CONSTANT ACCELERATION: Keep 30 sec or more
VEHICLE SPEED: 10 km/h (6 MPH) or more
ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
ENG SPEED: 450 rpm or more
5. If DTC is detected, go to CVT-83, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005928820
1.CHECK DTC
Perform CVT-83, "
DTC Confirmation Procedure".
Are any DTC displayed?
YES - 1>> DTC except for “P0730” is displayed: Go to Check the DTC detected item. Refer to CVT-48,
"CONSULT-III Function (TRANSMISSION)".
YES - 2>> DTC for “P0730” is displayed: Replace the transaxle assembly. Refer to CVT-180, "
