DIAGNOSIS

1. STEP 1. Check the accelerator cable adjustment. Q: Is the accelerator cable properly adjusted? YES : Go to Step 2. NO : Adjust the accelerator cable by referring to «ACCELERATOR CABLE CHECK AND ADJUSTMENT»(ref-236935-S10685315072006071200000) , and then go to Step 3 .
2. STEP 2. Check the accelerator pedal position sensor assembly. Check that the lever of the accelerator pedal position sensor assembly moves smoothly by moving it by hand. Q: Does the lever of the accelerator pedal position sensor assembly move smoothly? YES : Go to Step 3. NO : Replace the accelerator pedal position sensor assembly (Refer to «ACCELERATOR PEDAL POSITION SENSOR»(ref-236935-S03313816552006071200000) ), then go to Step 3.
3. STEP 3. Retest the system. Q: Does the throttle valve fully open and close? YES : The procedure is complete. NO : Return to Step 1 .

1. STEP 1. Check the accelerator pedal. Q: Is the accelerator pedal loose? YES : Tighten the fasteners, then go to Step 4 . NO : Go to Step 2.
2. STEP 2. Check the accelerator cable wiring. Q: Is the accelerator cable routing bent sharply? YES : Correct the cable routing, then go to Step 4 . NO : Go to Step 3.
3. STEP 3. Check the accelerator cable lubricant. Q: Is the accelerator cable lubricated sufficiently? YES : There is no action to be taken. NO : Refill or replace the lubricant, then go to Step 4.
4. STEP 4. Retest the system. Q: Does the accelerator pedal work normally? YES : The procedure is complete. NO : Return to Step 1 .

Scheme 1

1. Turn the A/C and lights OFF. Inspect and adjust the accelerator cable at no load.
2. Warm engine until stabilized at idle.
3. Confirm idle speed is at standard value. Standard value: 700 +/- 100 r/min
4. Stop the engine. [ignition switch: "LOCK" (OFF) position.]
5. Confirm there are no sharp bends in the accelerator cable.
6. Check the inner cable for correct slack. Standard value: 1.0-2.0 mm (0.04-0.08 inch)
7. If there is too much slack or no slack, adjust play by the following procedures. Loosen the look nut and fully close the throttle lever. Tighten the adjusting nut until just before the throttle lever starts to move. By loosening the adjusting nut one turn, the accelerator cable slack will be brought to the standard value. Fix the adjusting nut with the look nut. After adjusting, check that the throttle lever is touching the stopper.
