STEP 9. Check connector C-58 at ECM <M/T> or connector
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 10.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 14.

STEP 10. Check for harness damage between engine
coolant temperature sensor connector B-11 (terminal No.
2) and ECM connector C-58 (terminal No. 49) <M/T> or PCM
connector C-55 (terminal No. 57) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 14.
NO : Repair it. Then go to Step 14.

STEP 11. Check the engine coolant temperature sensor.
(1) Disconnect the engine coolant temperature sensor

connector B-11.

(2) Remove the engine coolant temperature sensor.

(3) With the temperature sensing portion of engine coolant

temperature sensor immersed in hot water, check
resistance.

Standard value:

14

− 17 kΩ [at −20°C (−4°F)]

5.1

− 6.5 kΩ [at 0°C (32°F)]

2.1

− 2.7 kΩ [at 20°C (68°F)]

0.9

− 1.3 kΩ [at 40°C (104°F)]

0.48

− 0.68 kΩ [at 60°C (140°F)]

0.26

− 0.36 kΩ [at 80°C (176°F)]

(4) Apply 3M

 AAD part number 8731 or equivalent on the

screw section of the engine coolant temperature sensor.

(5) Install the engine coolant temperature sensor, and tighten

to the specified torque.

Tightening torque: 29

± 10 N⋅m (22 ± 7 ft-lb)

Q: Is the resistance at the standard value?

YES : Go to Step 12.
NO : Replace the engine coolant temperature sensor. Then

go to Step 14.
