Between Intake air pressure sensor 2 output terminal (pink/white) “a” of ECU coupler and any other
ECU coupler terminal “b”.
If there is continuity, replace the wire harness.
4 Installed condition of Intake air
pressure sensor 2.
Check for looseness or pinch-
ing.
Improperly installed sensor

Reinstall or replace the sensor.
Turn the main switch to “ON”,
and then check the condition of
the fault code using the mal-
function mode of the Yamaha
