TPS Adjustment (DOHC)

Unplug TPS connector and loosen TPS mounting screws. Place a .025" (.63 mm) shim thickness gauge between throttle lever and throttle stop screw. See Fig 2 .
Connect ohmmeter between terminals "C" and "D". See Fig 1 . Turn TPS fully clockwise then slowly rotate TPS counterclockwise to locate position that ohmmeter changes from zero to infinity. Holding TPS at that position, tighten mounting screws snug-tight.
Ensure there is NO continuity between terminals "C" and "D" when 0.035" (0.9 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw.
Ensure continuity exists between terminals "C" and "D" when 0.012" (0.3 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw. Tighten TPS mounting screws to 30 INCH lbs. (3.4 N.m).
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.

CAUTION: DO NOT adjust Swift SOHC throttle stop screw to adjust idle. Throttle stop screw is factory set and is used as zero reference point for all other adjustments.
