(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.
