Throttle Position Sensor: Adjustments
THROTTLE POSITION SENSOR (TP SENSOR) ADJUSTMENT
NOTE: Before adjusting the TP Sensor, complete the basic idle speed adjustment.
1. Disconnect the throttle position sensor connector.
2. Using jumper wires, connect a voltmeter between terminal 1 and terminal 2 of the throttle position sensor connector.
3. Insert a 0.65 mm (0.0256 in.) thick feeler gauge between the fixed SAS and throttle lever.
4. Loosen the throttle position sensor mounting bolts and turn the TP Sensor body fully counterclockwise.
5. In this condition, check that there is continuity between terminals 1 and 2.
6. Slowly turn the throttle position sensor clockwise until you find a point at which there is no continuity between terminal 1 and 2. Then, tighten the
throttle position sensor mounting bolt securely.
7. Connect the throttle position sensor connector.
8. Connect the scan tool to the data link connector in the fuse box.
9. If the scan tool is not used, connect a voltmeter between throttle position sensor connector terminals 2 (sensor ground) and 3 (sensor output) using
pin.
NOTE
-
Do not disconnect the TP Sensor connector.
-
Use a digital type voltmeter to obtain an accurate value.
10. Turn the ignition switch "ON."
