z

P1xxx = additional emission relevant DTCs provided by manufacturer  

z

P2xxx = DTCs defined by SAE with specified texts, from MY 2000  

z

P3xxx = additional emissions relevant DTCs provided by manufacturer from MY 2000  

System group: 

z

Px0xx = Fuel and air ratio and additional emission regulations  

z

Px1xx = Fuel and air ratio  

z

Px2xx = Fuel and air ratio  

z

Px3xx = Ignition system  

z
