Step 2
1) Turn the ignition switch OFF.
2) Remove the air cleaner box. (!Page 103)
3) Disconnect the STP sensor coupler.
4) Check the continuity between each terminal and ground.
" STP sensor continuity: ∞ Ω (Infinity)
5) If OK, then measure the STP sensor resistance at the wire
terminals (between Yellow wire A and Black wire B).
6) Close and open the secondary throttle valve by finger, and
measure the valve closing and opening resistance.
" STP sensor resistance
Secondary throttle valve is closed : Approx. 0.5 kΩ
Secondary throttle valve is opened: Approx. 3.9 kΩ
7) If OK, then measure the STP sensor resistance at the wire
terminals (between Blue wire c and Black wire B).
" STP sensor resistance: Approx. 4.69 kΩ
# 09900-25008: Multi-circuit tester set
) Tester knob indication: Resistance (Ω)
Are the continuity and resistance OK?
YES Go to Step 3.
• Reset the STP sensor position correctly.
NO
• Replace the STP sensor with a new one.
8) After repairing the trouble, clear the DTC using SDS tool.
