(2)

Check for the continuity between the engine coolant
temperature sensor B-09 (terminal No. 1) and ground.

｠

Not continuity.

Q:Is the harness wire in good condition?

YES:

Go to Step 4.

NO:

Repair it. Then go to Step 5.

STEP 4. Check the engine coolant temperature sensor.

(1)

Disconnect the engine coolant temperature sensor
connector B-09.

(2)

Remove the engine coolant temperature sensor.

ZK603214AA00

(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)]

ZK603215AA00

(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 measured resistance at the standard value?

YES:

Replace the engine coolant temperature sensor. Then

go to Step 5.

NO:

Go to Step 5.

STEP 5. 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 - Pattern 24 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0117 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8.

NO:

It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points How to Cope
with Intermittent Malfunctions P.00-15.

CIRCUIT OPERATION

｠

5-volt voltage is applied to the engine coolant
temperature sensor output terminal (terminal No. 1)
from the ECM (terminal No. 26) via the resistor in
the ECM. The ground terminal (terminal No. 2) is
grounded with ECM (terminal No. 27).

｠

The engine coolant temperature sensor is a
negative temperature coefficient type of resistor. It
has the characteristic that when the engine coolant
temperature rises the resistance decreases.

｠

The engine coolant temperature sensor output
voltage increases when the resistance increases
and decreases when the resistance decreases.

TECHNICAL DESCRIPTION

｠

The engine coolant temperature sensor converts
the engine coolant temperature to a voltage and
outputs it.

｠

The ECM checks whether this voltage is within a
specified range.

DESCRIPTIONS OF MONITOR METHODS

Engine coolant temperature sensor output voltage
is out of specified range.
