4. If necessary, adjust the Sub Throttle Position Sensor (vehicles with TRAC only).
-
Loosen the 2 set screws of the sensor.
-
Apply vacuum to the Throttle Opener.
-
Insert a 0.40 mm (0.016 in.) thickness gauge. between the throttle stop screw and Throttle Valve gear.
-
Connect the test probe of an ohmmeter to the terminals IDL2 and E2 of the sensor.
-
Gradually turn the sensor clockwise until the ohmmeter deflects, and secure the sensor with the 2 set screws.
-
Recheck the continuity between terminals IDL2 and E2.
With 0.30 mm (0.0162 in) clearance between lever and stop screw you should measure continuity.
With 0.50 mm (0.020 in) clearance between lever and stop screw you should measure NO continuity.
5. Reinstall the Sub Throttle Actuator with the four screws (vehicles with TRAC only).
