EXHAUST GAS TEMPERATURE SENSOR INSPECTION [SKYACTIV-D 1.5]

id0140q2446300

Exhaust Gas Temperature Sensor No.1

Warning

• A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system.

Caution

• Perform exhaust gas temperature sensor removal/installation only when inspection or replacement is required, such as when DTCs for the sensor are displayed, because it may cause exhaust gas leaks.

• If removal/installation is performed, always verify that there is no exhaust gas leak after reinstallation.

Resistance inspection

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Remove the following parts:

(1) Engine cover (See ENGINE COVER REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

(2) Air cleaner (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

(3) Battery and battery tray (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

(4) Air inlet pipe, air hose and turbocharger air inlet hose (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

(5) Turbocharger solenoid valve (See TURBOCHARGER SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

3. Remove the exhaust gas temperature sensor No.1. (See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

4. Place the exhaust gas temperature sensor No.1 in water with a thermometer, and heat the water gradually.

5. Measure the resistance between exhaust gas temperature sensor No.1 terminals A and B.

• If not as specified, replace the exhaust gas temperature sensor No.1. (See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

Resistance

Water temperature (°C {°F})	Resistance (Kilohms)

Exhaust Gas Temperature Sensor No.3

Warning

• A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system.

Caution

• Do not allow flammable objects such as the taping for bundling wiring harness to come into contact with the catalytic converter.

• If removal/installation is performed, always verify that there is no exhaust gas leak after reinstallation.

Resistance inspection

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Lift up the vehicle.

3. Remove the front under cover No.2. (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

4. Remove the exhaust gas temperature sensor No.3. (See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

5. Place the exhaust gas temperature sensor No.3 in water with a thermometer, and heat the water gradually.

6. Measure the resistance between exhaust gas temperature sensor No.3 terminals A and B.

Exhaust Gas Temperature Sensor No.4

Warning

• A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system.

Caution

• Do not allow flammable objects such as the taping for bundling wiring harness to come into contact with the catalytic converter.

• If removal/installation is performed, always verify that there is no exhaust gas leak after reinstallation.

Resistance inspection

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Lift up the vehicle.

3. Remove the plate (exhaust system). (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

4. Remove the exhaust gas temperature sensor No.4. (See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

5. Place the exhaust gas temperature sensor No.4 in water with a thermometer, and heat the water gradually.

6. Measure the resistance between exhaust gas temperature sensor No.4 terminals A and B.
