Judgment Criteria

• Value of temperature of transmission fluid: 180°C

(356

°F) or more. (10 minutes)

.

OBD-II DRIVE CYCLE PATTERN

With the vehicle speed 10 km/h (6.2 mph) or more
and the throttle valve opening 12.5% or more, drive
for 10 minutes or more.

.

TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THIS CODE TO BE
SET ARE:)

• Malfunction of the transmission fluid temperature

sensor system (Short circuit) circuit

• Malfunction of the transmission fluid temperature

sensor

• Malfunction of the TCM

DIAGNOSIS

STEP 1. Check the TCM terminal voltage.
[C-38 TCM connector (vehicle side, connected)]
Turn ON the ignition switch, and check the voltage between ter-
minal No. 39 and No. 50.

• Transmission fluid 20°C (68°F): Approx. 2.52 V

• Transmission fluid 80°C (176°F): Approx. 0.69 V

Q: Is the check result normal?

YES : Go to Step 6.
NO : Go to Step 2.

STEP 2. Check the transmission fluid temperature sensor.
Refer to

P.23C-275

.

Q: Is the check result normal?

YES : Go to Step 3.
NO : Replace the valve body assembly.

STEP 3. Check the wiring harness between the
transmission fluid temperature sensor and TCM.
Check that the wiring harness between the A/T control solenoid
valve assembly connector and TCM is not shorted to the body
and other wiring harness.
Q: Is the check result normal?

YES : Go to Step 4.
NO : Repair or replace the failure section.

STEP 4. Check the TCM power supply and ground.
Q: Is the check result normal?

YES : Go to Step 5.
NO : Repair or replace the failure section.

STEP 5. Check the TCM connector pin terminal and the
connection status.
Q: Is there a failure point?

YES : Repair or replace the failure section.
NO : Replace the TCM.

STEP 6. Erase the DTC code, and drive the vehicle for a
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO : Replace the TCM.
