Why is my check engine light on? I have a 2005 road king with after market pipes and screaming eagle air breather. It also has a screaming eagle efi race tuner kit. I check the codes and it comes up p0134 and p0154 which is front and rear 02 sensor open/not responding. My bike doesn't have o2 sensors. Is there a way to not have these codes come up again? Is there a way to reprogram the ecm so its not looking for the o2 sensors?
