DTC P0730 BELT DAMAGE
Description INFOID:0000000004666954
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 Val ue in Data Monitor Mode INFOID:0000000004666955
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004666956
• This is not an OBD-II self-diagnostic item.
• TCM calculates the actual gear ratio with input speed sensor (primary speed sensor) and output speed sen-
sor (secondary speed sensor).
• Diagnostic trouble code “P0730 BELT DAMG” with CONSUL T-III is detected, when TCM receives an unex-
pected gear ratio signal.
Possible Cause INFOID:0000000004666957
Transaxle assembly
DTC Confirmation Procedure INFOID:0000000004666958
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays 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-91, " Diagnosis Procedure " .
Diagnosis Procedure INFOID:0000000004666959DTC Confirmation Procedure " .
Are any DTC displayed? YES - 1>> DTC except for “P0730 BELT DAMG” is displa
yed: Go to Check the DTC detected item. Refer to
CVT-51, " CONSULT-III Function (TRANSMISSION) " .
YES - 2>> DTC for “P0730 BELT DAMG” is displayed: Replace the transaxle assembly. Refer to CVT-182," Removal and Installation " .

DTC P0841 PRESSURE SENSOR FUNCTION
Description INFOID:0000000004667009
Using the engine load (throttle position), the primary pulley revolution speed, and the secondary pulley revolu-
tion speed as input signal, TCM changes the operating pr essure of the primary pulley and the secondary pul-
ley and changes the groove width of the pulley to control the gear ratio.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004667010
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004667011
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0841 PRESS SEN/FNCTN” wit h CONSULT-III is detected when correlation
between the values of the secondary pressure sensor and the primary pressure sensor is out of specifica-
tion.
Possible Cause INFOID:0000000004667012
• Transmission fluid pressure sensor A (Secondary pressure sensor)
• Transmission fluid pressure sensor B (Primary pressure sensor)
• Harness or connectors
(Sensor circuit is open or shorted.)
DTC Confirmation Procedure INFOID:0000000004667013
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays 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. Start engine and maintain the following conditions for at least 12 consecutive seconds.
VEHICLE SPEED: 40 km/h (25 MPH) More than
RANGE: “D” position
3. If DTC is detected, go to CVT-117, " Diagnosis Procedure " .
Diagnosis Procedure INFOID:0000000004667014CONSULT-III Function (TRANSMISSION) " .
Is any malfunction of the “ U1000 CAN COMM CIRCUIT ” indicated?
YES >> Check CAN communication line. Refer to
CVT-60 .
NO >> GO TO 2.
