Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004305658
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0725 ENGINE SPEED SIG” with CONSULT-III is detected when TCM does not
receive the engine speed signal (input by CAN communication) from ECM.
Possible Cause INFOID:0000000004305659
Harness or connectors
(The ECM to the TCM circuit is open or shorted.)
DTC Confirmation Procedure INFOID:0000000004305660
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, touch “ERASE” on “SELF-DIAG RESU LTS” and then perform the following procedure to con-
firm 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 10 consecutive seconds. PRI SPEED SEN: More than 1000 rpm

DTC P0730 BELT DAMAGE
Description INFOID:0000000004305662
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:0000000004305663
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004305664
• 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:0000000004305665
Transaxle assembly
DTC Confirmation Procedure INFOID:0000000004305666
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
