DIAGNOSTIC FUNCTION

TCM determines that the malfunction is present 
when the primary pulley speed sensor value 
changes abruptly or when there is a discrepancy 
between this sensor and other sensors in sensor 
reading.

.

DESCRIPTIONS OF MONITOR METHODS

• The status with the secondary pulley speed of 

500 r/min or more and with the primary pulley 
speed of 150 r/min or less continues for 5 sec-
onds.

• When the primary pulley speed has dropped 

abruptly from 1,000 r/min or more to 300 r/min or 
less, and then it keeps 300 r/min or less for 0.5 
seconds continuously.

.

MONITOR EXECUTION

• Transmission range: D

• Throttle valve opening : 1/8 or more

• Engine speed : 450 r/min or more

.

DTC SET CONDITIONS

Check Conditions

• Transmission range switch position: D.

• Secondary pulley speed: 500 r/min or more.

• Primary pulley speed at 10 millisecond before: 

1,000 r/min or more.

• Throttle position sensor voltage: 1.37 volts or 

more.

• Engine speed: 450 r/min or more.

• Voltage of battery: 9 volts or more.

• Voltage of battery: 16 volts or less.

JUDGMENT CRITERIA

• Primary pulley speed [secondary pulley speed: 

1000 r/min or more]: 300 r/min or less. (5 sec-
onds)

• Primary pulley speed [Primary pulley speed at 10 

millisecond before: 1,000 r/min or more]: 300 
r/min or less. (0.5 second)

.

OBD-II DRIVE CYCLE PATTERN

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

.

PROBABLE CAUSES

• Malfunction of primary pulley speed sensor

• Damaged wiring harness and connectors

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 1: Primary speed sensor signal (Refer to Data List Refer-
ence Table 

P.23A-127

.)

Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Go to Step 2.

STEP 2. Check the following connector:

• B-126 Primary pulley speed sensor connector

• C-37 TCM connector

• A-12 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 primary pulley speed sensor connector and 
the TCM connector
Between B-126 primary pulley speed sensor connector (termi-
nal 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.
