                     When replacing the HO2S perform the following:
                     |  
                   | • | A code clear with a scan tool, regardless of whether or not a DTC is set 
 
 |  
                   | • | HO2S heater resistance learn reset with a scan tool, where available 
 
 |  
                   | 
                     Perform the above in order to reset the HO2S resistance learned value and avoid possible HO2S failure.
