id0140s1446400

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 terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

2. Remove the turbocharger with variable turbine geometry. (See TURBOCHARGER WITH VARIABLE TURBINE GEOMETRY REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

3. Remove the exhaust gas temperature sensor No.1.
