Diagnostic mode 5: Check output of oxygen sensor signals 

Function 

The static values of the oxygen sensors are indicated via this diagnostic mode. 

The values of the individual oxygen sensor signal outputs must reach the specified value or must be within the 
min.- and max.- limits. 

Requirements 

z

There must not be any DTCs stored in DTC memory, see DIAGNOSTIC MODE 3: CHECK DTC 
MEMORY .  

z

Coolant temperature must be at least 80 °C, see DIAGNOSTIC MODE 1: CHECK MEASURED 
VALUES ; PID 5, Coolant temperature.  

Work procedure 

z

Connect diagnostic tester, see CONNECT DIAGNOSTIC TESTER .  

z

Start engine and let run at idle.  

z

Under address word 33, select "Diagnostic mode 5: Check output of oxygen sensor signals".  

z

Select the desired output of oxygen sensor signals "Test -ID XX".  

Evaluation of output of oxygen sensor signals:
