STEP 8. Check connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 9.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 11.

STEP 9. Check for open circuit between engine coolant
sensor connector B-11 (terminal No. 2) and ECM connector
C-60 (terminal No. 92) <M/T> or PCM connector C-54
(terminal No. 57) <A/T>.
Q: Is the harness wire in good condition?
YES : Replace the ECM or PCM. Then go to Step 11.
NO : Repair it. Then go to Step 11.

STEP 10. 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 : Replace the ECU or PCM. Then go to Step 11.
NO : Replace the engine coolant temperature sensor. Then
go to Step 11.
STEP 11. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function
− OBD-II Drive Cycle − Procedure 6 −
Other Monitor
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0118 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.
