Note: Before adjusting the throttle position sensor, the engine idling speed should be properly adjusted.
1. Check:
- Throttle position sensor
Refer to «Checking the throttle position sensor».
2. Adjust:
- Throttle position sensor angle
a. Connect the throttle position sensor coupler to the wire harness.
b. Connect the digital circuit tester to the throttle position sensor.
Positive tester probe yellow terminal «1».
Negative tester probe black/blue terminal «2».
Digital circuit tester: 90890-03174.
Model 88 Multimeter with tachometer: YU-A1927.
c. Measure the throttle position sensor voltage.
d. Adjust the throttle position sensor angle so the measured voltage is within the specified range.
Throttle position sensor voltage: 0.63-0.73 V.
e. After adjusting the throttle position sensor angle, tighten the throttle position sensor screws.
