TPS Adjustment
- Disconnect TPS harness connector and throttle opener vacuum hose. Using hand vacuum pump, apply 15 in. Hg vacuum to throttle opener to move throttle lever to idle position. Insert .012" (.30 mm) shim thickness gauge between throttle lever and throttle stop screw. See Figure
.
- Connect ohmmeter between terminals "C" (Black/Green wire) and "D" (Blue wire) of TPS connector. Loosen TPS mounting bolts and turn TPS fully clockwise, then turn TPS counterclockwise slowly to find position ohmmeter changes from infinity to 0 (zero) ohm. Tighten TPS mounting bolts at that position.
- Ensure there is NO continuity between terminals "C" and "D" when 0.016" (0.4 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw.
- Ensure there is continuity between terminals "C" and "D" when 0.008" (0.2 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw.
- If steps 3) and 4) DO NOT
result as indicated, TPS zero adjustment is incorrect, start adjustment sequence again. If second adjustment results are the same after readjusting, replace TPS.
- After final adjustment is completed, reconnect TPS connector and vacuum hose to throttle opener.
