Specifications
Service Data
B831G21107001
Injector
FI Sensors + Secondary Throttle Valve Actuator
Step Action Yes No
1 1) Turn the ignition switch to OFF.
2) Remove the seat. Refer to “Front Side Exterior Parts
Removal and Installation in Section 9D (Page 9D-6)”.
3) Check the FP relay coupler for loose or poor contacts.
If OK, then check the FP relay. Refer to “Fuel Pump
Relay Inspection in Section 1G (Page 1G-7)”.
Is the FP relay OK?
• Y/Bl wire open or
poor “19” connection.
• O/W wire open or
shorted to ground.
• R/B or Y/R wire open
or shorted to ground
or poor “16”
connection.
• If wire and
connection are OK,
intermittent trouble or
faulty ECM.
• Recheck each
terminal and wire
harness for open
circuit and poor
connection.
• Replace the ECM
with a known good
one, and inspect it
again.
Replace the FP relay
with a new one.
