Without Traction Control

ADJUSTMENT OF CLOSED THROTTLE POSITION SWITCH AND THROTTLE POSITION SENSOR (TPS)




(1) Disconnect the throttle position sensor connector.





(2) Using jumper wires, connect an ohmmeter across terminal (3) (closed throttle position switch) and terminal (4) (sensor ground) of the throttle position sensor.





(3) Insert a 0.65 mm (.0256 in.) thick feeler gauge between the fixed SAS and throttle lever.





(4) Loosen the throttle position sensor mounting bolts and turn the TPS body fully counterclockwise.
(5) In this condition, check that there is continuity across terminals (3) and (4).





(6) Slowly turn the throttle position sensor clockwise until you find a point at which there is no continuity across terminals (3) and (4) 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 (white).
(9) If not using the scan tool, proceed as follows:
(1) Disconnect the throttle position sensor connectors and connect the special tool, Test Harness Set, between the disconnected connectors.
(2) Connect a digital voltmeter between the throttle position sensor terminal 2 (sensor output) and terminal (-) (sensor ground).
(10) Turn the ignition switch ON (but do not start the engine).
(11) Check the throttle position sensor output voltage.

Standard value: 400 - 1,000 mV

(12) If the voltage is out of specification, check the throttle position sensor and associated harnesses.
(13) Remove the feeler gauge.
(14) Turn the ignition switch OFF.
