Diagnostic mode 5: Check output of oxygen sensor signals: Procedure

WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2005 Volkswagen Jetta, 2004 Volkswagen Jetta, 2003 Volkswagen Jetta, 2003 Volkswagen Golf, and 2002 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Connect diagnostic tester, see CONNECT DIAGNOSTIC TESTER .
Start engine and let run at idle.
Under address word 33, select "Diagnostic mode 5: Check output of oxygen sensor signals".
Select the desired output of oxygen sensor signals "Test -ID XX".
