<When using the scan tool MB991958>
1. Connect the scan tool MB991958 to the diagnosis connector.
2. Remove the two accelerator pedal position sensor assembly mounting bolts (M8 bolt) and then insert a thickness gauge with a thickness of 0.60
mm (0.024 in.) in between the accelerator lever and the fully-closed stopper.
3. Turn the ignition switch to the "ON" position (without starting the engine).
4. Loosen the accelerator pedal position sensor mounting bolt and then turn the accelerator pedal position sensor anti-clockwise as far as it will go.
5. Check that the accelerator pedal position switch turns on at this time.
6. Turn the accelerator pedal position sensor clockwise until the point is found where the accelerator pedal position switch turns off. Securely tighten
the accelerator pedal position sensor mounting bolt at this point.
7. Check that the accelerator pedal position sensor (main) output at this time is within the standard value range.
Standard value: 0.5 - 0.9 volt
