I have cleaned all the plugs and switches with switch cleaner still having a error code 20 So didn't know if it was the 02 sensor ?

I don't have any direct experience, so can't offer any "real world" advice. Hopefully, one our experienced techs will be along soon!

Won't be the O2 sensor. It is either the atmospheric pressure sensor itself or a clogged hose or the intake air pressure sensor itself or clogged hose. The service manual shows how to test these 2 sensors with a multimeter.

I have not had this issue so haven't had to locate these components but the service manual diagram shows the atmospheric sensor under the seat near the battery. The intake air pressure sensor looks to be under the tank.

The last thing the service manual says could cause this fault is a faulty ECU but that is pretty unlikely.
