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 [SKYACTIV-D 1.5].)

2. Remove the following parts:

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

(2) Fresh-air duct (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

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

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

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

(6) 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.

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. Turn the steering wheel to full right lock.

2. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].)

3. Lift up the vehicle.

4. Remove the front splash shield No.1 (RH). (See SPLASH SHIELD REMOVAL/INSTALLATION.)

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

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

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 [SKYACTIV-D 1.5].)

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.
