Hey, '01 F4i has a blink code of 2 slow 3 fast blinks. A member on here said it was an O2 heater code. Thye only problem is that I see no O2 sensor on my exhaust, nor is there a bung that would recieve one. I'm new to bikes but expierenced in mechanics and I was just wondering if I have a non OEM header on here or something. Any insight would be appreciated, thanks!

 

Okay, I checked the online manual and it is a O2 heater fault, but that is only in reference to california models. Could I have an ECM for a California bike and not know it?

 

On honda cars that code is for knock sensor, you might check it out.

Have you reset the ecu?
