1.

Ignition switch "OFF"

2.

Disconnect battery (-) cable.

3.

Refer to "Shop Manual" and disconnect Engine Coolant Temperature Sensor connector.

4.

Measure the resistance between Pin No. 3 (Signal) terminal and Pin No. 1 (Ground) terminal of Engine Coolant Temperature Sensor harness connector.

Specification : Refer to table below

Temp.(℃)	Temp.(℉)	Resistance(kΩ)	Temp.(℃)	Temp.(℉)	Resistance(kΩ)
-40	-40	48.14	40	104	1.15
-20	-4	14.13 ~ 16.83	60	140	0.59
0	32	5.79	80	176	0.32
20	68	2.31 ~ 2.59

5.

Is the measured value within specification?

▶ Fault might be intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and control module memory is not cleared yet. Thoroughly check terminal of battery, all connectors ( and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

▶ Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

▶ Carefully re-do this troubleshooting guide steps.

▶ If no problems were found with the circuits or connectors, Engine Coolant Temperature Sensor and then go to "Verification of Vehicle Repair" procedure.

caution

Note that engine coolant may flow out from the water temperature control assembly when removing the sensor.

caution

- Install the component with the specified torques.

- Note that internal damage may occur when the component is dropped or mis- treated.

caution

- Insert the sensor in the installation hole and be careful not to damage.

6.

Ignition switch "OFF".

7.

Disconnect Battery (-) terminal.

8.

Refer to "Shop Manual" and disconnect remove thermostate.

9.

Immerse the thermostate in water and gradually heat the water.(Refer to Figure below)

10.

Check for the valve opening temperature.

Specification :

Valve opening Temp. : 82±1.5℃(179.6±1.5℉)

Full opening Temperature : 95℃(203℉)

11.

Check for valve lift.

Specification : 0.3in(8mm) or more at 203℉(95℃)

12.

Is the measured value within specification?

▶ Carefully re-do this troubleshooting guide steps.

▶ If the diagnostics have been performed correctly with no failure found, replace the ECM and then go to "Verification of Vehicle Repair" procedure.

caution

When replacing the ECM/PCM, the vehicle equipped with the immobilizer must be performed procedure as below.

[In the case of installing used ECM/PCM]

1) Perform "ECM Neutral mode" procedure with GDS. (Refer to "Immobilizer" in BE group)

2) After finishing "ECM Neutral mode", perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)

[In the case of installing new ECM/PCM]

Perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)

caution

When replacing the ECM/PCM, the vehicle equipped with the smart key system (Button start) must be performed procedure as below.

[In the case of installing used ECM/PCM]

1) Perform "ECM Neutral mode" procedure with GDS. (Refer to "Smart key" in BE group)

2) After finishing "ECM Neutral mode", insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the ECM/PCM learns the smart key information automatically.

[In the case of installing new ECM/PCM]

Insert the key (or press the start button) and turn it to the IGN ON and OFF position. Then the ECM/PCM learns the smart key information automatically.

▶ Carefully re-do this troubleshooting guide steps.

▶ If no problems were found with the circuits or connectors, Thermostat and then go to "Verification of Vehicle Repair" procedure.

note

Install the Thermostat with the jiggle valve upward.
