4) Disconnect the TP sensor coupler.
5) Check the continuity between W/Br wire and
ground.
6) Also, check the continuity between W/Br wire
and Gr/R wire
C. If the sound is not heard from the tester, the
circuit condition is OK.
7) Disconnect the ECU coupler.
8) Check the continuity between W/Br wire and
terminal 31.
9) Also, check the continuity between Y/B wire
and terminal .
TPS lead wire continuity: Continuity (sound)
Is the continuity OK?
YES Go to step 1 and step 2
Y/B wire or Gr/R wire open, or Gr/R
NO
wire shorted to ground
10) After repairing the trouble, clear the DTC
using Diagnosis tool.
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the TP sensor coupler.
3) Check the continuity between W/Br wire and
ground.
TP sensor continuity: ∞ Ω (Infinity)
(White/Brown – Ground)
4) If OK, then measure the TP sensor
resistance at the terminals (between Bottom
and Center pin).
5) Turn the throttle grip and measure the
resistance.
TP sensor resistance
Throttle valve is closed: Approx. 1.1 kΩ
Throttle valve is opened: Approx. 4.4 kΩ
6) If OK, then measure the TP sensor
resistance at the terminals (between Upper
and Center pin).
TP sensor resistance: Approx. 4.66 kΩ
(Upper pin – Center pin)
