3) Disconnect the STP sensor coupler.
4) Check the continuity between each terminal and ground.
"
STP sensor continuity:
∞
Ω
(Infinity)
(Terminal – Ground)
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 k
Ω
Secondary throttle valve is opened: Approx. 3.9 k
Ω
(Yellow
A
– Black
B
)
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 k

Are the continuity and resistance OK?
8) After repairing the trouble, clear the DTC using SDS tool.
