THROTTLE CABLE ADJUSTMENT

  1. With throttle valve closed, accelerator pedal play should be 0.08-0.27" (2.0-7.0 mm). Use lock nut and adjusting nut on cable bracket to adjust free play. (Scheme 1)
  2. With accelerator pedal fully depressed, check clearance between throttle lever and lever stopper at throttle body. If clearance is not 0.02-0.07" (0.5-2.0 mm), correct by changing height of pedal stopper bolt located under accelerator pedal. After throttle cable adjustment is complete, adjust transmission kickdown cable.
  3. Check A/T cable free play. (Scheme 1) If clearance is not 0.03-0.06" (0.8-1.5 mm), use lock nut and adjusting nut on cable bracket to adjust free play.

TP SENSOR ADJUSTMENT

  1. Disconnect negative battery cable. Unplug TP sensor connector and insert 0.026" (0.65 mm) shim thickness gauge between throttle lever and throttle stop screw. Loosen TP sensor mounting screws. Using ohmmeter, check resistance between TP sensor terminals "A" and "B". See «THROTTLE POSITION SENSOR RESISTANCE»(ref-26178-S08434823772001010500000) table.
  2. Turn TP sensor fully counterclockwise and then turn it clockwise slowly to locate point where ohmmeter reading changes from zero to infinity. Holding TP sensor at that position, tighten TP sensor mounting screws snug.
  3. Ensure continuity does not exist between terminals "A" and "B" when 0.031" (0.8 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw. (Scheme 2)and (Scheme 3).
  4. Ensure continuity exists between terminals "A" and "B" when 0.020" (0.5 mm) shim thickness gauge is inserted between throttle lever and throttle stop screw. Tighten TP sensor mounting screws to 22.8-38.4 INCH lbs. (2.5-4.5 N.m).
  5. If continuity is not as specified in steps 3) and 4), TP sensor zero adjustment is incorrect. Start adjustment sequence again. If results are the same after readjusting, replace TP sensor. After final adjustment is completed, reconnect TP sensor connector.
