P0069
Intake air pressure sensor or atmospheric pressure sensor: when
the main switch is turned to "ON", the intake air pressure sensor
voltage and atmospheric pressure sensor voltage differ greatly.
Execute the diagnostic mode.
(Code No. 03)
When engine is stopped:
Atmospheric pressure at the
current altitude and weather
conditions is indicated.
0 m above sea level: Approx.
101 kPa (757.6 mmHg, 29.8
inHg)
3000 m (9800 ft) above sea lev-
el: Approx. 70 kPa (525.0
mmHg, 20.7 inHg)
Displayed value is incorrect →
Replace the intake air pressure
sensor.
Execute the diagnostic mode.
(Code No. 02)
When engine is stopped:
Atmospheric pressure at the

Displayed value is incorrect →
Replace the atmospheric pres-
sure sensor.
Replace the ECU.
Refer to "REPLACING THE

Confirm that the fault code has
a condition of "Recovered" us-
ing the Yamaha diagnostic tool,
and then delete the fault code.
