4-70 FI SYSTEM DIAGNOSIS
Step 2
1) Turn the ignition switch to OFF.
2) Remove the air cleaner box and lift up the throttle body.
(5-13)
3) Disconnect the STP sensor coupler.
4) Install the test harness to the STP sensor.
5) Check the continuity between each terminal and ground.
 STP sensor continuity: ∞ Ω (Infinity)
 09900-25008: Multi-circuit tester set
09900-28630: TPS test wire harness
6) If OK, then measure the STP sensor resistance at the wire
terminals (between terminal B and terminal C).
7) 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
 Tester knob indication: Resistance (Ω)
