Exhaust Gas Temperature Sensor No. 2

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