DTC SET CONDITIONS

Check Conditions

• Transmission range switch position: D.

• Throttle position sensor voltage: 1.37 volts or

more.

• Primary pulley speed: 1,000 r/min or more.

• Secondary pulley speed at 10 millisecond before:

500 r/min or more.

• Voltage of battery: 9 volts or more.

• Voltage of battery: 16 volts or less.

JUDGMENT CRITERIA

• Secondary pulley speed [primary pulley speed:

1,000 r/min or more]: 150 r/min or less. (5 sec-
onds)

• Secondary pulley speed [secondary speed at 10

millisecond before: 500 r/min or more]: 260 r/min
or less. (0.5 second)

.

OBD-II DRIVE CYCLE PATTERN

Transmission range: D (Drive the vehicle for 10 sec-
onds or more while the accelerator opening angle is
20% or more)

.

PROBABLE CAUSES

• Malfunction of secondary pulley speed sensor

• Damaged wiring harness and connectors

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 2: Secondary speed sensor signal (Refer to Data List Ref-
erence Table

P.23A-127

.)

Q: Is the check result normal?

YES : Intermittent malfunction
NO : Go to Step 2.

STEP 2. Check the following connector:

• C-37 TCM connector

• B-124 Secondary pulley speed sensor connector

• B-13 Intermediate connector

Check the terminals for a contact status problem and internal
short circuit.
Q: Is the check result normal?

YES : Go to Step 3.
NO : Repair the defective connector.

STEP 3. Check for open circuit in the wiring harness
between the secondary pulley speed sensor connector
and the TCM connector.
Between B-124 secondary pulley speed sensor connector (ter-
minal No.3) and C-37 TCM connector (terminal No.48)
Q: Is the check result normal?

YES : Go to Step 4.
NO : Repair the wiring harness.

STEP 4. Check for open circuit and short to ground in the
wiring harness between the secondary pulley speed
sensor connector and the TCM connector
Between B-124 secondary pulley speed sensor connector (ter-
minal No.2) and C-37 TCM connector (terminal No.36)
Q: Is the check result normal?

YES : Go to Step 5.
NO : Repair the wiring harness.

STEP 5. Check for open circuit in the wiring harness
between the CVT control relay and the secondary pulley
speed sensor connector.
Between A-18X CVT control relay (terminal No.3) and B-124
secondary pulley speed sensor connector (terminal No.1)
Q: Is the check result normal?

YES : Go to Step 6.
NO : Repair the wiring harness.

STEP 6. Secondary pulley speed sensor check
Visually check the tip of the sensor for foreign materials or
damage.
Q: Is the check result normal?

YES : Go to Step 7.
NO : Repair.

STEP 7. Diagnostic trouble code recheck after replacing
the secondary pulley speed sensor
Q: Is the check result normal?

YES : The inspection is complete.
NO : Replace TCM.

DTC P0725: Malfunction of Engine Speed

.

DIAGNOSTIC FUNCTION

TCM detects malfunction of engine speed received
from the ECM by comparing the primary pulley
speed with the secondary pulley speed.

.

DESCRIPTIONS OF MONITOR METHODS

• Primary pulley speed of 1,000 r/min or more and

with the engine speed of 450 r/min or less

• When the differences in rotation between the

engine and the primary pulley, and between the
engine and the secondary pulley are 1,000 r/min
or more during direct-coupled operating

• CAN communication error occurs between ECM

and TCM.

.

MONITOR EXECUTION

• Transmission range: D

• Throttle valve opening : 1/8 or more

.
