Output voltage inspection
Connect the test harness to the ECM (page 5-8).
Measure the voltage at the test harness terminals (page 5-9).
CONNECTION:
- BARO sensor: B1 (+) - B8 (-)
- MAP sensor: B1 (+) - B7 (-)
- STANDARD: 2.7 - 3.1 V
The BARO and MAP sensor output voltage (above) is measured under the standard atmosphere (1 atm = 1,030 hPa).
The BARO and MAP sensor output voltage is affected by the distance above sea level, because the output voltage is changed by atmosphere.
Check the sea level measurement and be sure that the measured voltage falls within the specified value.
BARO sensor removal and installation
Remove the seat (page 2-2).
Remove the tool box cover (page 16-7).
Remove the screw and disconnect the BARO sensor 3P connector.
Remove the BARO sensor.
Installation is in the reverse order of removal.
MAP sensor removal and installation
Remove the air cleaner housing (page 5-51).
Remove the screws, MAP sensor and O-ring.
Installation is in the reverse order of removal.
Install and tighten the screws to the specified torque.
Torque: 2.1 N·m (0.21 kgf·m, 1.5 lbf·ft).
Always replace О-ring with a new one.
