Step 2
1) Turn the ignition switch OFF.
2) Disconnect the STP sensor coupler.
3) Check the continuity between Yellow wire terminal and
ground.
! STP sensor continuity: ∞ Ω (Infinity)
6) If OK, then measure the STP sensor resistance at the coupler
(between Yellow and Black wires).
7) Close and open the secondary throttle valve fully by moving
the fast idle link, and measure the valve closing and opening
resistance.
! STP sensor resistance
Secondary throttle valve is closed A : Approx. 0.5 kΩ
Secondary throttle valve is opened B: Approx. 3.9 kΩ
8) If OK, then measure the STP sensor resistance at the wire
terminals (between Blue wire and Black wire).
! STP sensor resistance: Approx 4.69 kΩ

% 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.
9) After repairing the trouble, clear the DTC using SDS tool.
