On a 2019 model, the Code 3A relates to the purge valve and canister. This is located behind the top right-hand fairing. I would inspect the canister and check the wiring at the canister solenoid and the rubber hoses at the air box. As the air filter has been swapped, maybe someone screwed up with the hoses and/or wiring at the air box.

The Code 67 relates to the Oxygen Sensor Heater which is built into the Oxygen sensor in the exhaust. As your exhaust has been swapped, I would start looking at the O2 sensor and then follow the wiring. Maybe they forgot to plug O2 sensor back into the wiring harness.

I am not sure where you ordered your OBD2 sensor from, but there is a specific wiring harness adapter cable you need as well.

 

Thank you! I have three OBD 2 readers and what I ordered was the adapter with the red end, which I believe is what the 2023 uses. What I am confused about, is that if the air filter swap or the exhaust swap is the cause for the codes, I would have thought because I rode over 500 miles with no error codes that it would have thrown those codes earlier.

 

That evap system must be monitored on the new bike? If so, it doesn't fail immediately.

With our cars, you fill the fuel tank and drive around. As the fuel warms up, it expands and the vapor pressure increases, in the tank which is connected to the charcoal cylinder. . If you didn't tighten your gas cap, the pressure never increased.

The system had to fail to see pressure under different circumstances before the light popped on.

 

On the euro 5 bike, the o2 sensor needs to see a emissions legal range within 45 seconds, or it would throw a code. That's the only point of any of this is to make sure the bike is emissions compliant.

If you let a bike, or car run out of the legal range, error free, for even 1 mile you would violate the euro laws and Nancy Pelosi would drive over to your house and beast the crap out of you for violating California emissions.

 

So weirdest thing I tried clearing the code with my Bluetooth adapter and it would not connect. Then I tried my second Bluetooth adapter it would not connect then I tried my cheap code clearer/ reader and it connected no problem and I cleared the code. Then I rode it 7 miles to my friend's house, turn the bike off, turn it back on and the light was on again! Very disappointed. I did not read the code at that time because I figured it was the same one that I had earlier which is not life threatening, it's for the heater of the O2 sensor. So we drove our bikes for a few hours and I shut the bike off to hit the men's room, (Cycle 1? ) Drove to a pub to have a sandwich and a beer, shut the bike off (cycle two? ) . Drove home put it in my garage and shut the bike off (cycle 3)? Went in the house to get my code reader to read the code again turn the bike on tyhere is no check engine light! So I'm still baffled. I'm wondering if my code reader turned the light off but didn't erase the ECU? And then doing the three Cycles which is what the manual tells you to do to clear it manually, is what actually cleared it? Very confusing but as of right now it has no code so I don't know what to do.
