5-44 FI SYSTEM DIAGNOSIS
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the TP sensor coupler and ECM coupler.
3) Install the test harness to the TP sensor.
4) Check the continuity between terminal
A and ground.
$ TP sensor continuity: ∞ Ω (Infinity)
(Terminal
A – Ground)
5) If OK, then measure the TP sensor resistance at the test har-
ness terminals (between terminal
A and terminal
B).
6) Turn the throttle grip and measure the resistance.
$ TP sensor resistance
Throttle valve is closed: Approx. 1.1 kΩ
Throttle valve is opened: Approx. 4.3 kΩ
7) If OK, then measure the TP sensor resistance at the test har-
ness terminals (between terminal
C and terminal
D).
$ TP sensor resistance: Approx. 5.0 kΩ
(Terminal
C – Terminal
D)
! 09900-25008: Multi-circuit tester set
09900-28630: TPS test wire harness
% Tester knob indication: Resistance (Ω)
Are the continuity and resistance OK?
8) After repairing the trouble, clear the DTC using SDS tool.
