  • Unfortunately I don't have the service manual for that vehicle, but the P1226 code indicates that there is a wire problem for the injector #2. Since you know that the injector is OK, then the next step is to check the wires from the injector to the Engine Control Module (ECM)

  • Thank you so much, appreciate the help. Best regards
