Note

•  Perform the following test only when directed.

Resistance Inspection

Warning

•  When the engine and exhaust system are hot, they can cause severe burns or injury. 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.

1.  Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)

2.  Remove the exhaust gas temperature sensor. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZR-CD 2.2].)

3.  Place the exhaust gas temperature sensor in water with a thermometer, and heat the water gradually.

4.  Measure the resistance between exhaust gas temperature sensor terminals A and B.
