STEP 4. 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 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 6.

STEP 5. 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 6.
NO : Replace the engine coolant temperature sensor. Then
go to Step 6.
STEP 6. 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 P0117 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

CIRCUIT OPERATION
• 5-volt voltage is applied to the engine coolant
temperature sensor output terminal (terminal No.
1) from the ECM (terminal No. 83) <M/T> or PCM
(terminal No. 44) <A/T> via the resistor in the
ECM <M/T> or PCM <A/T>. The ground terminal
(terminal No. 2) is grounded with ECM (terminal
No. 92) <M/T> or (terminal No. 57) <A/T>.
• The engine coolant temperature sensor is a neg-
ative temperature coefficient type of resistor. It
has the characteristic that when the engine cool-
ant temperature rises the resistor decreases.
• The engine coolant temperature sensor output
voltage increases when the resistor increases
and decreases when the resistor decreases.
.
TECHNICAL DESCRIPTION
• The engine coolant temperature sensor converts
the engine coolant temperature to a voltage and
output it.
• The ECM <M/T> or PCM <A/T> checks whether
this voltage is within a specified range.
.
DESCRIPTIONS OF MONITOR METHODS
Engine coolant temperature sensor output voltage is
out of specified range.
.
MONITOR EXECUTION
