TPS Adjustment (SOHC)

  1. Unplug TPS connector and loosen TPS mounting screws. Insert .024" (.6 mm) shim thickness gauge between throttle lever and throttle stop screw. Connect ohmmeter between TPS terminals "A" and "B". See Fig 1 and Fig 2 .
  2. Turn TPS fully counterclockwise, then turn TPS clockwise to locate position that ohmmeter changes from zero to infinity. Holding TPS at that position, tighten TPS mounting screws snug-tight.
  3. Ensure there is NO continuity between terminals "A" and "B" when 0.035" (0.9 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw.
  4. Ensure continuity exists between terminals "A" and "B" when 0.012" (0.3 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw. Tighten TPS mounting screws to 18 INCH lbs. (2.0 N.m).
  5. If steps 3) and 4) results are NOT as indicated, TPS zero adjustment is incorrect, start adjustment sequence again. If results are the same after readjusting, replace TPS. After final adjustment is completed, reconnect TPS connector.
