Hi
I am having Trouble Codes (P1603, P1604 and P1605) with my Car, It is Toyota Vitz, 2014, 1000cc/1KR-FE

  • No Check Engine Light
  • No Significant Problem with Drive or Mileage so far.
  • Minor Roughing or Vibration when Engine is Idle
  • No Problem with Engine Start, it gets start on first attempt/self.

Just curious if these codes are alarming for something to worry about.

Thanks in advance...!
