EXHAUST GAS TEMPERATURE SENSOR INSPECTION [SKYACTIV-D 2.2]

id0140z7446300


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

Resistance inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the exhaust gas temperature sensor No.1. (See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

3.  Place the detection part of the exhaust gas temperature sensor No.1 in the water and while gradually increasing the water temperature, measure the resistance between exhaust gas temperature sensor No.1 terminals A and B.

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.
•  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.
