06 fazer 1000 fault code 20

[Val]

Think error code 20 is air intake sensor fault, there is one top of the air filter housing. Unplug it and clean it , check for any loose wires and corrosion, see if that clears the fault.
I assume you have the gen2 fuel injected fazer, not gen1 the carb version.

:agree

Two sensors can give code 20 - Good idea to download service manual from download section here: http://foc-u.co.uk/index.php?action=down...ew;down=12
