Throttle Sensor Testing (A/T)
1.
Disconnect sensor connector.
2.
Connect ohmmeter between sensor terminals "E" and "IDL."
3.
Insert a 0.1 mm (0.004 in) feeler gauge between throttle stop screw and stop lever. Meter should indicate continuity.
4.
Switch to a 0.6 mm (0.024 in) gauge. Meter should indicate no continuity.
5.
Connect ohmmeter between sensor terminals "VT" and "E." Slowly open throttle and verify a linear increase in resistance, from below 1K ohms
with throttle fully closed to approximately 5K ohms with throttle fully open.
6.
Adjust sensor if specifications cannot be obtained. Refer to ADJUSTMENT PROCEDURES.
7.
If correct specifications are not obtained following adjustment, replace sensor.
