Throttle Body Test

NOTE:
  • Do not adjust the throttle stop screw. It is preset at the factory.
  • If the malfunction indicator lamp (MIL) has been reported on, check for diagnostic trouble codes (DTCs) (see GENERAL TROUBLESHOOTING INFORMATION ).
  1. With the engine off, check the throttle cable movement. The cable should move without binding or sticking.
    • If the cable moves OK, go to step 2.
    • If the cable binds or sticks, check it and its routing. If the cable is faulty, reroute it or replace it, then adjust it (see RESONATOR REMOVAL/INSTALLATION  ). Go to step 2.
  2. Move the throttle lever by hand to see if the throttle valve and/or shaft are too loose or too tight.
    • If there is excessive play in the throttle valve shaft, or any binding in the throttle valve at the fully closed or fully opened position, replace the throttle body.
    • If the throttle valve and shaft are OK, go to step 3.
  3. Connect the HDS to the data link connector (DLC).
  4. Turn the ignition switch ON (II).
  5. Check the throttle position with the HDS. The reading should be about 0°(REL), 0 % (REL) or 0.5 V when the throttle is fully closed and about 80° (REL), 89 % (REL) or 4.5 V when the throttle is fully opened.
    • If the throttle position is correct, the throttle body is OK.
    • If the throttle position is not correct, replace the throttle body.
