Fast Idle Knob Installation; Map Sensor Output Voltage Inspection; Map Sensor Removal/Installation - Honda 2010 CRF250R Service Manual

INSTALLATION
Install the fast idle knob and tighten the lock nut to the
specified torque.
TORQUE : 2.3 N-m (0.2 kgf.m,1.7Ibf-ft)
Instalilhe throttle body (page 5-52).
MAP SENSOR
OUTPUT VOLTAGE INSPECTION
Connect the HDS pocket tester (page 5-13),
Connect the 12 V battery ("ECM" selector switch is ON)
(page 5-12).
View the voltage with HDS pocket tester.
Standard : 2.7 - 3.1 V
The MAP sensor output voltage (above) is measured
under the standard atmosphere ( 1 aIm
=
1.013 hPa).
The MAP sensor output voltage is affected by the
distance above sea level, because the output voltage is
changed by atmospheric pressure.
Check the altitude and be sure that the measured
voltage falls within the specified value.
REMOVAL/INSTALLATION
Hang the fuel tank to the left side of the frame
(page 3-6).
