HARNESS INSPECTION PROCEDURE

TROUBLESHOOTING HINTS
Hint 1:The throttle position sensor signal is more important in the control of automatic transaxle than in the engine control. Shifting shock and other troubles will be caused if this sensor is faulty.
Hint 2:If the output voltage of the throttle position sensor is out of specification, adjust the sensor and check the voltage again. If there is an evidence of disturbed fixed SAS setting, adjust the fixed SAS.

SENSOR INSPECTION
(1) Disconnect the throttle position sensor connector.





(2) Measure resistance between terminal (4) (sensor ground) and terminal (1) (sensor power).

Standard value: 3.5 - 6.5 K Ohms





(3) Connect a pointer type ohmmeter between terminal (4) (sensor ground) and terminal (2) (sensor output).
(4) Operate the throttle valve slowly from the idle position to the full open position and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
(5) If the resistance is out of specification, or fails to change smoothly, replace the throttle position sensor.

Torque: 2.0 Nm (1.5 ft-lbs.)
