I get this code every now and the and it is sporadic. The code is for the atmospheric pressure sensor or the air pressure sensor voltage is different. I thought the battery might not be fully charged as I only track this bike and from what I have read the R1 is not battery friendly. Put a new Shorai in an code still is there. Dealer is getting new sensors so maybe one is actually bad. Anyone have thoughts or have had this code.

I replaced the air intake pressure sensor and it seems to be ok know. Keeping my fingers crossed. I am going to have the dealer order another sensor as it is the same sensor as the atmospheric pressure sensor. I also checked for pinched hoses and other things. Hopefully that fixed the problem.

I have the same problem........replaced the sensors....problem persist. Did anyone ever find a different reason?

I got the code 20. I removed the air box and cleaned both censors (intake n throttle housing). Code cleared but came back on.

Checked wire looms n hoses. Seems good. So I ordered two new ones. Hope that resolves it. I will update i a few weeks.

UPDATE:

I changed the sensor in the airbox. A buddy who is a mechanic told me most sensors that he has replaced are in the airbox only which has fixed the problem. He suggested just try that one first.

So I played the odds he told me. Replaced the airbox one only. Started up, code still showing after warm up. Said the Eff word and turned off bike.

Restarted a few min later, code is gone!! Turned off. Few minutes re started, code still off and remained off for test ride around the block.

I will keep other sensor as a spare. Here is a photo of how they look installed for reference. They have green tags on them which is oem.

Hey all. I have recently been dealing with the same issue and was hoping there would be more insight on this issue. I have had an intermittent fault code 20. I've replaced both of the sensors and it still shows the code after a test ride. Unfortunately, this disables the Launch Control capabilities. Does anyone have any other ideas as to what could be causing the code? And does anyone know if there is a way to bypass the code to get Launch Control back online? Thanks!!!

Darn code is back. This is really frustrating. Sure wish someone had the answer.

My error 19 and 20 experiences have all been with my ignition (rusted contacts from riding in the rain or being parked for a long time in humid weather) or multifunction relay on its way out.

Troubleshoot or replace both if you can.

I've got code 20 as well.

Diagnostic mode is showing 2 kPa delta in pressure between the sensors with the bike not running. Can anyone (who doesn't have engine code posted) tell me how close their atmospheric and intake pressure readings are with the bike not running (Diag codes 02 and 03)? I realize they should be dead on in theory, just wondering how much tolerance these sensors have.

Thanks!
