Heated Oxygen Sensor 
(HO2S) after Three Way 
Catalytic Converter (TWC), 
checking 
     
Notes:  
     
G130 = O2S behind three way catalytic 
converter, bank 1 
     G131 = O2S behind three way catalytic 
converter, bank 2 
     For functional check of O2S behind three way 
catalytic converter -G130- or -G131-   Repair 
Group 01, Read measuring value block, display 
group 041 
     
-  Disconnect connector for O2S behind three way 
catalytic converter -G130- or- G131- (component 
locations  page 24
-1 ). 
    
If there is continuity:  -  Using multimeter (Fluke 83 or equivalent) set for measuring resistance 
( ), check for continuity (short circuit) between oxygen sensor 
terminals 3 (GND wire) and 4 (signal wire).
