Shielding the O2 Sensor Wire

[Len Sabatine]

     Braided ground shield seems to work best , both ends grounded.
     It does help remove any Rf garbage from the signal .
     A Scope will show how much trash is present in the general area.
    There's filtering built into the ECM for this purpose as well.
