- Throttle position sensor (from the throttle body)
2. Check:
- Throttle position sensor
a. Connect the pocket tester (Ωx1k) to the throttle position sensor as shown.
Pocket tester: 90890-03112.
Analog pocket tester: YU-03112-C.
Tester positive lead → Blue «1»
Tester negative lead → Black/Blue «2»
b. Check the throttle position sensor maximum resistance.
Out of specification → Replace the throttle position sensor.
Maximum throttle position sensor resistance 4-6 kΩ at 20°C (68°F)
c. Connect the pocket tester (Ωx1k) to the throttle position sensor as shown.
Tester positive lead → Yellow «3»
Tester negative lead → Black/Blue «2»
d. While slowly opening the throttle, check that the throttle position sensor resistance is within the specified range.
The resistance does not change or it changes abruptly → Replace the throttle position sensor.
Throttle position sensor resistance: 0-6 kΩ at 20°C (68°F)
3. Install:
- Throttle position sensor
Note: When installing the throttle position sensor, adjust its angle properly. Refer to «Adjusting the throttle position sensor».
