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.

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].)
