Step 3
1) Connect the TP sensor coupler 1 to the test harness.
2) Turn the ignition switch ON.
3) Measure the TP sensor output voltage at the coupler
(between + BI/B and - B/Br) by turning the throttle grip.
" TP sensor output voltage
Throttle valve is closed:
Throttle valve is opened: Approx. 4.41 V
# 09900-25008: Multi-circuit tester set
* Tester knob indication: Voltage (+)
Is the voltage OK?
• R, B/Br or BI/B wire open or shorted to ground,
or poor 6, D or K connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
If check result is not satisfactory, replace TP sen-
NO
sor with a new one.
4) After repairing the trouble, clear the DTC using SDS tool.
